Rechargeable behind-the-ear hearing device kit for adults with hearing loss

Evaluation of Efficacy and Effectiveness of the Investigational Sonova Behind-the-Ear Rechargeable Hearing Device Kit 2 - 2025

Not applicable Interventional Sonova AG · NCT07414329

Adults who already use hearing aids will try a rechargeable behind-the-ear hearing device kit for about two weeks to see if it improves listening in noisy places and speech understanding.

What this trial studies

This interventional study asks experienced adult hearing-aid users to wear a rechargeable behind-the-ear (BTE/RIC) device kit for approximately two weeks with a minimum daily wear time, paired to their smartphone as needed. Participants receive an initial clinic fitting and complete lab speech-in-noise tests and questionnaires comparing performance with the investigational device to an unaided condition and to their personal hearing device experience. The protocol emphasizes challenging real-world listening situations and collects subjective user-experience data alongside objective speech-understanding measures. Follow-up testing occurs at the end of the wear period to determine whether the device provides measurable and meaningful benefits.

Who should consider this trial

Good fit: Ideal candidates are adults (18+) who are current, experienced hearing-aid users with mild to profound bilateral hearing loss, comfortable using a smartphone, and socially active in noisy settings.

Not a fit: People who are not current hearing-aid users, who have ear-canal issues that prevent fitting, who cannot operate a paired smartphone, or whose hearing falls outside the device fitting range may not receive benefit.

Why it matters

Potential benefit: If successful, the rechargeable BTE kit could help users understand speech better in noisy environments and offer a convenient, satisfactory hearing-aid option.

How similar studies have performed: Similar commercial rechargeable behind-the-ear hearing devices have previously shown modest improvements in user satisfaction and speech-in-noise performance, so the approach is an extension of existing technology rather than entirely novel.

Eligibility criteria

Show full inclusion / exclusion criteria
Inclusion Criteria:

* Adults (aged 18 years or older)
* Current and experienced hearing aid users (actively using hearing aids for at least 3 months)
* Audiograms that fit within the fitting range of the devices (mild to profound bilateral hearing loss)
* Cognitive and functional capability to consent to study procedures, operate the controls for the devices and comply with all directions during the study.
* Good understanding (read/write/speak) of the English language.
* Willingness to comply with all study requirements including minimum wear-time (6-8 hrs/day) of binaural BTE(RIC) investigational devices.
* Good overall health including healthy outer ear with no excessive wax/debris.
* Ear canal size/shape must accommodate appropriate fitting of the hearing device.
* Socially engaged participants are a top priority (out \& active socially) who frequently encounter the noisy situations in which the devices are meant to be used.
* Use/ownership of a smartphone to pair hearing aids with for use with phone calls and streaming.
* Otherwise, the study population is representative of typical hearing instrument users in age and presence of hearing loss

Exclusion Criteria:

* Significant medical conditions that, in the opinion of the investigators, are likely to interfere with study procedures or likely to confound study endpoint.
* Contraindications to medical device (MD) in this study: known hypersensitivity or allergy to investigational product/domes.
* Limited ability to describe listening impressions/experiences and the use of the hearing aid.
* Acute tinnitus (\<three months after onset).
* Inability to attend scheduled visits (mobility and/or scheduling).
