<title>Introduction</title>
<p>Understanding hearing aid wearer experiences in real-world settings is important to provide responsive and individualized hearing care. This study aimed to describe real-life benefits of hearing aids (HAs), as reported by hearing aid wearers through Ecological Momentary Assessment (EMA) in various listening environments.</p>
</sec>
<sec>
<title>Method</title>
<p>Qualitative content analysis of 1,209 open-text responses, provided through self-initiated EMAs, was conducted. The de-identified data was collected retrospectively via a smartphone app compatible with these HAs. Only text responses reflecting positive hearing aid experiences were analyzed. The 1,209 open-text responses were categorized into 18 pre-determined sub-categories, further organized into five overarching categories: Conversational, Leisure, Device-related aspects, Lifestyle, and Other factors.</p>
</sec>
<sec>
<title>Results</title>
<p>Across these categories, 48 self-generated meaning units highlighted the multifaceted benefits of HAs. In particular, participants reported significant improvements in conversational settings, specifically during phone conversations and meetings, attributed to improved sound quality and speech understanding when wearing their HAs. During leisure activities, particularly TV watching and music listening, clearer sound and ease of Bluetooth streaming contributed to experienced benefits. Lifestyle improvements were reported in occupational and social settings, as hearing aid wearers stated enhanced communication and sound awareness. Device-related factors contributing to positive wearer experiences included extended battery life and the convenience of rechargeable batteries. The most prominent sub-category, other factors, underscored overall satisfaction, comfort with the device, and improved auditory experiences across various environments.</p>
</sec>
<sec>
<title>Conclusion</title>
<p>This study reveals the diverse benefits of HAs in improving communication, listening experiences, and quality of life across various settings, as captured through EMA. By emphasizing features like direct streaming and rechargeability, the findings highlight the importance of personalized hearing care and the potential of real-time listener feedback to inform device enhancements and support strategies, advancing more tailored and effective hearing rehabilitation.</p>

<title>1 Introduction</title>
<p>Hearing rehabilitation aims to enhance hearing functioning, participation, and quality of life for individuals with hearing loss (Boothroyd, <xref ref-type="bibr" rid="B3">2007</xref>). Providing amplification through hearing aids (HAs) is a primary component of hearing care, as HAs amplify sound and improve the clarity of sounds, with a specific emphasis on speech and communication (Ferguson et al., <xref ref-type="bibr" rid="B10">2017</xref>). However, the effectiveness of HAs depends on wearers being familiar with the correct way to handle the devices, understanding the expected benefits and satisfaction, and the clinicians&#x00027; ability to create personalized and achievable rehabilitation plans with the HAs (Heselton et al., <xref ref-type="bibr" rid="B19">2022</xref>; Humes, <xref ref-type="bibr" rid="B23">2003</xref>; Wong et al., <xref ref-type="bibr" rid="B48">2003</xref>). A recent study that included former HA wearers revealed that almost half of them attributed non-use to device-related issues such as wearing comfort, not liking to wear the HAs, or limited perceived benefit (Franks and Timmer, <xref ref-type="bibr" rid="B11">2023</xref>; Mothemela et al., <xref ref-type="bibr" rid="B31">2023</xref>). It is therefore important to explore the factors contributing to HA wearers&#x00027; experiences, in order to enhance understanding of HA benefit and satisfaction from the wearer&#x00027;s perspective, provide person-centered care, and validate the effectiveness of treatment with HAs.</p>
<p>Satisfaction is commonly measured through self-reported measures, often referred to as patient-reported outcome measures (PROMs) (Timmer et al., <xref ref-type="bibr" rid="B42">2018</xref>; Oosthuizen et al., <xref ref-type="bibr" rid="B32">2022</xref>). Self-reported questionnaires can, for instance, gather information about the individual&#x00027;s perspective on how well rehabilitation goals have been achieved in real-world settings (von Gablenz et al., <xref ref-type="bibr" rid="B47">2021</xref>). Some limitations of PROMs include that they necessitate client input based on memory and experiences with specific listening conditions. As memory affects recall, this can introduce recall bias. Also, listening situations posed in PROMs might not apply to all HA wearers (Timmer et al., <xref ref-type="bibr" rid="B42">2018</xref>). Ecological momentary assessment (EMA) has been proposed to address some limitations of PROMs, by asking participants to repeatedly report on their experiences during or close in time to an event of interest (Bolger et al., <xref ref-type="bibr" rid="B2">2003</xref>; Shiffman et al., <xref ref-type="bibr" rid="B36">2008</xref>). EMA, also known as ambulatory assessment or experience sampling (Trull and Ebner-Priemer, <xref ref-type="bibr" rid="B43">2014</xref>), is a real-time data collection method, applied in participants&#x00027; real-world environments. EMA allows the capturing of individuals&#x00027; daily experiences and changes in their experiences over time (Holube et al., <xref ref-type="bibr" rid="B22">2020</xref>).</p>
<p>In practical terms, EMA research today commonly employs personal digital devices, utilizing auditory or vibratory alerts to prompt participants to respond to a series of questions throughout the day. This prompted EMA approach involves participants receiving messages on their smartphone-based app at regular intervals to complete surveys (Burke et al., <xref ref-type="bibr" rid="B5">2017</xref>). Patients may not always comply with the EMA data collections, as the highly dense data collection can burden participants. This limitation arises when patients do not provide feedback when prompted, thereby restricting the coverage of the analysis. This could lead to inadequate results, as they might fail to accurately portray the diverse range of experiences people have (Holube et al., <xref ref-type="bibr" rid="B22">2020</xref>; Schinkel-Bielefeld et al., <xref ref-type="bibr" rid="B35">2020</xref>). An alternative approach to prompted EMA is self-initiated EMA. During self-initiated EMA, the individuals decide when something of interest has happened, and subsequently fill in a survey on their initiative, without any prompting (Schinkel-Bielefeld et al., <xref ref-type="bibr" rid="B35">2020</xref>).</p>
<p>In addition to being used in research, EMA is also proposed as a valuable clinical tool, enabling patients to monitor daily challenges systematically and contributing to personalized hearing healthcare (Schinkel-Bielefeld et al., <xref ref-type="bibr" rid="B35">2020</xref>). Data collected through EMA could guide healthcare professionals in tailoring HA settings to meet individual patient needs during fitting, fine-tuning, and acclimation (Holube et al., <xref ref-type="bibr" rid="B22">2020</xref>). Combined with a person-centered care approach, such data can enhance understanding, leading to improved health outcomes. These rich data collection methods could also facilitate improved communication between patients and healthcare professionals, particularly concerning patient-specific needs and residual hearing difficulties experience in real life situations (Wu et al., <xref ref-type="bibr" rid="B50">2015</xref>; Brice and Almond, <xref ref-type="bibr" rid="B4">2022</xref>).</p>
<p>Most studies on hearing-related EMA have predominantly utilized quantitative methodologies to capture experiences with HAs and their features (Galvez et al., <xref ref-type="bibr" rid="B13">2012</xref>; Hasan et al., <xref ref-type="bibr" rid="B18">2014</xref>; Timmer et al., <xref ref-type="bibr" rid="B41">2017</xref>; Wu et al., <xref ref-type="bibr" rid="B49">2018</xref>). However, there remains a notable scarcity in the application of EMA for gathering qualitative data, such as personal experiences with HAs in real-life scenarios. Notably, Galvez et al. (<xref ref-type="bibr" rid="B13">2012</xref>) undertook a qualitative analysis of prompted EMA data to explore hearing difficulties among HA wearers, providing valuable insights for evaluating HA parameters and enhancing patient care. Similarly, Vercammen et al. (<xref ref-type="bibr" rid="B45">2023</xref>) identified key themes in feedback from HA wearers using automated text analysis of self-initiated EMA data, revealing a predominance of positive experiences related to communication and sound quality, in contrast to challenges in HA management.</p>
<p>While recent technological advancements, such as real-time speech-to-text transcription and advanced natural language processing (NLP) techniques, provide unprecedented opportunities for capturing and analyzing qualitative wearer feedback (Manchaiah et al., <xref ref-type="bibr" rid="B29">2021a</xref>,<xref ref-type="bibr" rid="B30">b</xref>), their full potential has yet to be explored. To complement insights from such computational methods, this study employs a manual qualitative analysis to delve into a portion of the dataset previously investigated by Vercammen et al. (<xref ref-type="bibr" rid="B45">2023</xref>) using NLP techniques. This methodological decision is intentional, addressing the constraints of computational methods, which may lack the depth and nuanced understanding inherent in direct human analysis (Jiang et al., <xref ref-type="bibr" rid="B24">2021</xref>; Baden et al., <xref ref-type="bibr" rid="B1">2022</xref>). Employing this approach, our study seeks to gain a more thorough understanding of the qualitative EMA data, with a particular emphasis on identifying psychosocial elements of satisfaction with HA usage (Oosthuizen et al., <xref ref-type="bibr" rid="B32">2022</xref>; Knoetze et al., <xref ref-type="bibr" rid="B26">2023</xref>). To this end, we focused on a subset of the original dataset, focusing on positive HA experiences only. Thereby providing a unique perspective, as opposed to the commonly reported challenges with HAs.</p>

<title>2 Materials and methods</title>
<sec>
<title>2.1 Study design</title>
<p>The study considered a retrospective subset of the data presented in Vercammen et al. (<xref ref-type="bibr" rid="B45">2023</xref>) i.e., 1,209 positive open-text statements provided by real-world HA wearers as part of their hearing care. Due to size of the dataset, this manuscript focused on positive responses only, with negative responses being analyzed as part of an upcoming manuscript. Prior to participation, participants were informed of de-identified data analysis for clinical and research purposes per the mobile application&#x00027;s data privacy notice. In addition, no personal identifying information was logged to ensure participant privacy. Institutional Review Board clearance was granted (HUM023/0922) prior to data analysis.</p>
</sec>
<sec>
<title>2.2 Study participants, material, and apparatus</title>
<p>The de-identified data was collected through a smartphone mobile application compatible with commercially available HAs, fitted to real-world HA wearers from English-speaking countries, i.e., Australia, Canada, England, Ireland, New Zealand, and the United States. Clinicians activated the EMA application feature within the fitting software during consultations. Clinicians could activate the feature to use as a real-time feedback system whenever they deemed it advantageous for the HA wearer and their hearing care (Vercammen et al., <xref ref-type="bibr" rid="B45">2023</xref>). Participants initiated the mobile application on their own when they had a listening experience that they wanted to report (i.e., self-initiated EMA) and navigated through the windows (see <xref ref-type="supplementary-material" rid="SM1">Supplementary material 1</xref>) (a) indicate the listening experience as positive or negative; (b) select the listening situation from the list, closest to the experienced situation (i.e., activities, battery or charging, entertainment, hearing children, in meeting, in restaurant, in vehicle, listening music, other, phone conversations, playing games, quiet conversations, shopping, social activities, social event, streaming media, worship, and watching TV); (c) provide description of the listening experience (open text field).</p>
</sec>
<sec>
<title>2.3 Data extraction and data cleaning</title>
<p>Between May 2018 and June 2021, an initial sample of 30,127 self-initiated EMAs on real-world HA experiences were collected worldwide and extracted from cloud-based data logging of the smartphone mobile application. Text statements shorter than 20 characters were removed for content quality, and a manual data cleaning process was conducted to correct spelling mistakes, remove nonsense text, and exclude non-English entries. Following data extraction and cleaning, a dataset of 5,331 negative and 3,462 positive EMAs (a total of 8,793 responses) was extracted. Only the 3,462 positive EMA&#x00027;s were considered for further analysis in this study (see <xref ref-type="fig" rid="F1">Figure 1</xref>). During data familiarization, it was found that some of the comments under each pre-determined sub-category (which were derived from the listening situation self-selected by the user&#x02014;see <xref ref-type="supplementary-material" rid="SM1">Supplementary material 1</xref>, panel B) were unrelated to the specific situation the participant had chosen (i.e., they were more applicable to another pre-determined sub-category). In addition, some of the comments were negative despite the participant&#x00027;s choice of a positive experience. After a discussion with the research team (IO, FMA, VM, CV, and DWS) a consensus was reached, and 799 open text statements were reclassified (i.e., moved to a more applicable sub-category), and 2,150 comments were moved from positive experiences to negative experiences. Furthermore, 103 comments could not be coded as they were irrelevant to any pre-determined sub-category. A final sample of 1,209 positive self-initiated EMAs was considered for further analysis (see <xref ref-type="fig" rid="F1">Figure 1</xref>).</p>

<sec>
<title>2.4 Data analysis</title>
<p>The final 1,209 positive self-initiated EMAs were analyzed using qualitative content analysis (Graneheim and Lundman, <xref ref-type="bibr" rid="B16">2004</xref>; Knudsen et al., <xref ref-type="bibr" rid="B27">2012</xref>). This approach was deemed suitable due to the diverse range of responses obtained from the open-ended question, which varied significantly in depth and detail. Qualitative content analysis involves an iterative process of revisiting and refining coding and categorization, facilitating a nuanced and comprehensive understanding of the data. Initially, responses within each of the 18 pre-determined subcategories, derived from the users&#x00027; selected listening situations in the app (e.g., phone conversations, watching TV etc.), were reviewed, coded and condensed into meaning units, capturing the essence of each participant&#x00027;s experience (Graneheim and Lundman, <xref ref-type="bibr" rid="B16">2004</xref>). These condensed meaning units were further examined and the sub-categories were grouped into broader categories, resulting in five main categories: Conversational, leisure, device-related, lifestyle, and other factors. To ensure clarity, we have detailed the hierarchical classification process used in our data analysis. Seemingly similar responses were placed in distinct categories based on their contextual relevance and the nuances of participant comments. This approach aimed to capture the multifaceted nature of hearing aid experiences. However, we acknowledge the potential overlap of similar responses in different categories and have included this consideration in Section 4.1.</p>
<p>To ensure consistency and reliability, an experienced qualitative researcher cross-checked 50% of the coding, and any discrepancies were resolved through team discussions. This iterative review process allowed for refining the categories, ensuring they accurately represented the data. The final categorization facilitated the identification of 48 self-generated meaning units, providing a comprehensive understanding of the diverse benefits of hearing aids as experienced by participants in their daily lives. This detailed categorization process ensured that the diverse and nuanced experiences of hearing aid users were systematically captured and analyzed, yielding robust insights into the real-world benefits of HAs.</p>

<title>3 Results</title>
<p>The 18 pre-determined sub-categories were categorized into five categories as part of the manual qualitative content analysis: (1) Conversational, representing diverse settings where participants engaged in conversations; (2) Leisure settings, representing various recreational pursuits for enjoyment and relaxation; (3) Device-related aspects, encompassing different facets of HA functionality; (4) Lifestyle factors, covering settings that contribute to an individual&#x00027;s way of life and daily routines; and (5) Other factors, including settings not falling within the aforementioned domains. From these categories, a total of 48 meaning units were self-generated (see <xref ref-type="table" rid="T1">Tables 1</xref>&#x02013;<xref ref-type="table" rid="T5">5</xref>).</p>

<p>Category 1: Conversational setting benefits of HAs</p>
<p>Six pre-determined sub-categories i.e., phone conversations (<italic>n</italic> = 86), quiet conversations (<italic>n</italic> = 64), in vehicle (<italic>n</italic> = 59), in meeting (<italic>n</italic> = 45), in restaurant (<italic>n</italic> = 43), and hearing children (<italic>n</italic> = 35) were combined into the overarching category &#x0201C;conversational settings&#x0201D; (see <xref ref-type="fig" rid="F2">Figure 2</xref>). Twenty self-generated meaning units were identified (see <xref ref-type="table" rid="T1">Table 1</xref> and <xref ref-type="supplementary-material" rid="SM1">Supplementary material 2</xref> for elaboration on meaning units). Within phone conversations, the largest identified meaning unit of listening experience (<italic>n</italic> = 32) focused on aspects such as volume and general satisfaction. The direct streaming capability facilitated seamless call handling, introducing a private and hands-free dimension to phone conversations. In quieter settings, participants enjoyed their ability to engage in one-on-one conversations, emphasizing the significance of both sound quality and improved speech understanding. In vehicle settings, improved sound quality, ease of conversing with passengers, and greater enjoyment of music and audio contributed to enhanced listening experiences. Participants also experienced increased participation and improved speech understanding during group conversations such as meetings and in noisy restaurant environments. Furthermore, participants reported improved communication with children, highlighting enhanced speech understanding and sound quality.</p>

<p>Category 2: Leisure activity benefits of HAs</p>
<p>Four pre-determined sub-categories i.e., watching TV (<italic>n</italic> = 227), listening music (<italic>n</italic> = 60), entertainment (<italic>n</italic> = 6), and playing games (<italic>n</italic> = 5) were combined into the overarching category &#x0201C;leisure settings&#x0201D; (see <xref ref-type="fig" rid="F2">Figure 2</xref>). Nine self-generated meaning units were identified (see <xref ref-type="table" rid="T2">Table 2</xref> and <xref ref-type="supplementary-material" rid="SM1">Supplementary material 3</xref> for elaboration on meaning units). Watching TV was the most frequently selected predetermined subcategory with listening experience identified as the largest meaning unit (<italic>n</italic> = 143) followed by sound quality (<italic>n</italic> = 46), speech understanding (<italic>n</italic> = 20), and direct screening (<italic>n</italic> = 18). These indicate the primary perceived benefits for the HA wearers in this specific leisure activity. Some participants also reported enhanced music listening experiences, noting improved recognition of lyrics, and vibrant sound quality. Greater enjoyment of other media, such as improved listening to radio, gaming, and podcast streaming, was also mentioned.</p>

<title>4 Discussion</title>
<p>This study employed a qualitative content analysis to explore positive real-world HA use experiences of a large sample of HA wearers, who provided self-initiated EMAs through a smartphone application. The pre-determined sub-categories that resulted from the users in-app responses were grouped into categories, as part of the manual qualitative content analysis, and consisted of (1) conversational settings, (2) leisure-related, (3) lifestyle-related, and (4) device-related aspects, and (5) other listening situations (see <xref ref-type="supplementary-material" rid="SM1">Supplementary materials 2</xref>&#x02013;<xref ref-type="supplementary-material" rid="SM1">6</xref> for more detailed examples of the sub-categories and meaning units).</p>
<p>The cornerstone of hearing rehabilitation is using HAs to improve access to sounds and speech, thereby enhancing communication&#x02014;a fundamental aspect of daily life (Ferguson et al., <xref ref-type="bibr" rid="B10">2017</xref>). This study particularly highlighted the significant benefits in conversational settings, with a notable emphasis on the advantages of smartphone-connected HAs in facilitating effective telephone communication. The rise in smartphone ownership among adults in the United States and the United Kingdom since 2015 has paralleled an increase in research into smartphone-connected HAs, underscoring improvements in phone conversation quality, speech intelligibility, and reduced listening effort thanks to direct streaming capabilities (Maidment et al., <xref ref-type="bibr" rid="B28">2019</xref>; Gomez et al., <xref ref-type="bibr" rid="B14">2022</xref>; Pew Research Center, <xref ref-type="bibr" rid="B33">2022</xref>). Moreover, the capacity for wearers to self-manage their HAs via a smartphone app has not only contributed to enhanced wearer satisfaction and integration into daily routines but has also empowered wearers through improved autonomy and ownership over their hearing experience (Chasin, <xref ref-type="bibr" rid="B7">2017</xref>). Direct streaming, particularly for media and communication via videotelephony platforms, has been identified as a pivotal feature, aligning with the trend toward greater technological integration within HA design. This trend underscores the importance of connectivity in augmenting the wearers experience, fostering enhanced engagement with modern communication platforms (Chasin, <xref ref-type="bibr" rid="B7">2017</xref>), and thereby enriching both listening experiences and social connections. Enhanced speech understanding was consistently reported, particularly in intimate settings such as conversations with spouses, further demonstrating the value of real-time EMA in providing detailed insights into everyday listening environments outside typical scenarios. Across various settings&#x02014;from quiet conversations to dynamic social events&#x02014;improvements in sound quality have been central to the wearer&#x00027;s enhanced ability to engage in meaningful interactions (Cox et al., <xref ref-type="bibr" rid="B8">2014</xref>), reinforcing the critical role of sound quality in effective communication (Kaplan-Neeman et al., <xref ref-type="bibr" rid="B25">2012</xref>).</p>
<p>In occupational settings, HAs significantly enhanced communication and sound awareness, aligning with prior research emphasizing the critical role of hearing in professional environments and the heavy reliance of wearers on their devices in such settings (Granberg and Gustafsson, <xref ref-type="bibr" rid="B15">2021</xref>; Timmer et al., <xref ref-type="bibr" rid="B40">2023</xref>). This study extends these insights by demonstrating positive experiences even in traditionally challenging situations such as group meetings and noisy environments (Picou, <xref ref-type="bibr" rid="B34">2020</xref>; Oosthuizen et al., <xref ref-type="bibr" rid="B32">2022</xref>), where HAs facilitated effective communication and sound source localization in the workplace. These findings, consistent with earlier studies, underscore the efficacy of HAs in improving occupational performance and highlight the unique value of self-initiated EMA data in capturing real-life, wearer-specific experiences, thus advocating for improved person-centered care. The positive feedback from self-initiated EMAs not only highlights the functional benefits of hearing technology in challenging situations but also underscores its impact on social engagements and interactions with close companions. This enhancement of communication and social involvement echoes previous findings on the significance of audiological interventions for improving the quality of life among individuals with hearing impairments (Holman et al., <xref ref-type="bibr" rid="B21">2021</xref>).</p>
<p>It is widely recognized that, in addition to speech clarity, effective communication, and sound quality (Picou, <xref ref-type="bibr" rid="B34">2020</xref>; Oosthuizen et al., <xref ref-type="bibr" rid="B32">2022</xref>), HA wearers value device usage during leisure activities such as watching television (Strelcyk and Singh, <xref ref-type="bibr" rid="B37">2018</xref>), enjoying music, and gaming (Greasley et al., <xref ref-type="bibr" rid="B17">2020</xref>). The same was found in this study&#x00027;s analysis of leisure-related experiences, where watching TV and listening to music were the two most self-selected leisure-related sub-categories. Specifically, the enhanced appreciation of listening to and performing music when using HAs reported in our study, supported the survey results by Greasley et al. (<xref ref-type="bibr" rid="B17">2020</xref>). Participants also reported improved speech clarity during several recreational activities, contributing to enhanced participation and enjoyment e.g., while playing netball, hiking, and taking guitar lessons. Improved listening experiences while playing computer games were also mentioned.</p>
<p>In contrast to general situations included in typical self-report questionnaires (Timmer et al., <xref ref-type="bibr" rid="B42">2018</xref>), the findings of this study offer deeper insights into the nuanced benefits and satisfaction derived from hearing aid use in specific lifestyle-related activities, such as airline travel&#x02014;a context scarcely documented in existing literature. The unique capacity of EMA to capture real-time feedback across diverse life situations not only enriches our understanding of hearing aid utility but also provides a rich dataset for informing device design and clinician support strategies. This granular insight, especially from unique contexts like airline travel, can serve as valuable data, guiding the development of HAs optimized for both common and complex environments. Moreover, the documented psychosocial benefits, including enhanced engagement in social settings and increased self-assurance in communication, underscore the comprehensive impact of HAs on wearers&#x00027; wellbeing (Holman et al., <xref ref-type="bibr" rid="B20">2019</xref>, <xref ref-type="bibr" rid="B21">2021</xref>; Vercammen et al., <xref ref-type="bibr" rid="B44">2021</xref>; Gomez et al., <xref ref-type="bibr" rid="B14">2022</xref>; Oosthuizen et al., <xref ref-type="bibr" rid="B32">2022</xref>). These findings highlight the transformative potential of hearing rehabilitation, affirming its role in improving not just hearing but the overall quality of life. Thus, by leveraging EMA data, clinicians are empowered to make nuanced adjustments that address the full spectrum of wearers&#x00027; needs, fostering improved hearing care that is as dynamic as the lives of the individuals it aims to support.</p>
<p>HA wearers also attributed positive experiences to the battery life and convenience of rechargeable HAs in terms of device-related experiences. Similarly, participants in a previous study reported that rechargeable technology is reliable and offers consistent performance (Taneja, <xref ref-type="bibr" rid="B39">2020</xref>). Rechargeable HAs, noted for their reliability and consistent performance (Taneja, <xref ref-type="bibr" rid="B39">2020</xref>), offer an eco-friendly alternative to disposables, simplifying daily routines and reducing costs (Sun, <xref ref-type="bibr" rid="B38">2019</xref>). Despite the ease of recharging, the straightforward replacement of disposable batteries was also appreciated since it can avoid downtime due to batteries needing to be recharged. This emphasizes the importance of person-centered care that supports wearers to make informed choices based on differentiated advantages related to rechargeable and replaceable battery devices and considers proficiency in HA management skills (Campos et al., <xref ref-type="bibr" rid="B6">2014</xref>).</p>
<p>Participants reported a range of benefits from using HAs, including enhanced hearing optimization, the ability to adjust volume for improved hearing range, and fewer needs to ask for repetitions, classified under the &#x0201C;Other&#x0201D; sub-category. Wearers reported wearing HAs comfortably throughout various daily activities, even during sleep, and valued the discreetness of their devices. This inconspicuousness plays a crucial role in diminishing the stigma often associated with HAs, fostering a more positive wearer attitude and enhancing overall device satisfaction (Maidment et al., <xref ref-type="bibr" rid="B28">2019</xref>). Additionally, the enriched perception of environmental sounds&#x02014;ranging from the natural ambiance of birds and waves to the everyday sounds of home appliances&#x02014;further underscores the comprehensive benefits of HAs. These improvements contribute to a more engaging and emotionally positive auditory experience, underlining the significant role HAs play in facilitating wearers&#x00027; active participation in life&#x00027;s diverse scenarios and mitigating communication challenges.</p>
<sec>
<title>4.1 Limitations</title>
<p>To our knowledge, this study is the first to perform a manual qualitative content analysis on self-initiated EMA data. However, several limitations should be acknowledged. Primarily, the data was collected as part of clinical practice and intended to support HA wearers and clinicians, and thus not initially collected for research (Friedman et al., <xref ref-type="bibr" rid="B12">2015</xref>). This secondary use of the data, while insightful, introduces challenges related to data quality and generalizability, as also acknowledged in studies by Verheij et al. (<xref ref-type="bibr" rid="B46">2018</xref>) and Dillard et al. (<xref ref-type="bibr" rid="B9">2020</xref>).</p>
<p>The exclusive use of a specific brand of smartphone-connected HAs, including the functionality that had to be activated by the clinician, limited participation, potentially introducing a selection bias toward a more technologically adept and motivated subgroup. Also, we included responses from individuals who provided feedback in English only. The absence of detailed demographic and audiological profiles of participants further restricts the findings&#x00027; applicability across a broader HA wearers&#x00027; population.</p>
<p>Additionally, the use of the mobile application&#x00027;s pre-determined sub-categories (i.e., pre-determined listening situations presented in-app for the user to respond to and select) to guide the categorization and grouping of responses may have constrained the coding process. While this classification ensured consistency, it might have limited the exploration of emergent themes not predefined in the app. We acknowledge the potential overlap of similar responses in different categories as a methodological limitation, as the predefined sub-categories imposed a structure not necessarily shared by all participants. Furthermore, the reliance on self-initiated EMAs introduces potential biases related to participant self-selection and memory recall, as users may selectively report experiences they perceive as significant. The voluntary nature of feedback and the potential for retrospective reporting introduces risks regarding compliamce and recall bias, respectively (Shiffman et al., <xref ref-type="bibr" rid="B36">2008</xref>). In addition, this study focuses exclusively on positive self-initiated EMA responses, presenting a partial view of the overall hearing aid experience. The exclusion of negative responses means that while the study highlights significant benefits, it does not document the full range of user experiences, including potential challenges and negative aspects. Additionally, a follow-up paper is underway to analyze the negative EMA feedback, which will complement this work and provide a more balanced understanding of hearing aid experiences. Furthermore, the free-text EMA method, while rich in detail, can be time-consuming for participants, which may influence engagement and data comprehensiveness.</p>
<p>Future studies could benefit from enhanced app instructions and prompts, alongside efforts to capture a more diverse participant demographic to broaden the research&#x00027;s relevance. Addressing these limitations in future research would help in obtaining more generalized and comprehensive insights into the real-world benefits of hearing aids.</p>

<title>5 Conclusions</title>
<p>Qualitative self-initiated EMA with positive sentiment has demonstrated its potential to uncover the diverse benefits of HAs, offering unique insights into the wearer&#x00027;s experience in real-world settings. The effort participants invest in free-text EMAs yields significant insights, particularly when analyzing positive EMA statements. This study confirms the substantial role of HAs in enhancing listening experiences, sound quality, and communication, even in less documented contexts such as air travel. Features like direct streaming, extended battery life, and rechargeability were particularly valued, bolstering satisfaction and supporting audiologists in delivering personalized auditory solutions. An innovative use of EMA through smartphone apps could enable wearers to contribute feedback spontaneously, allowing for example the immediate analysis of voice notes via NLP strategies. This could extract meaningful themes in real-time, informing clinicians or activating support mechanisms (i.e., specialized chatbots) to assist individuals in those exact moments of need. Employing this technology could lead to more dynamic, responsive, and person-centered hearing care, leveraging personal narratives to address the intricacies of daily life for HA wearers and enhance hearing rehabilitation strategies.</p>
