The summary describes a self-fitting hearing aid system that uses software to guide the user through a fitting procedure and adjust settings based on user input. There is no mention of AI or ML algorithms being used for this process, only a "self-fitting strategy" that integrates user input.
Yes
The device is intended to compensate for impaired hearing by amplifying sound for individuals with hearing impairment. This addresses a medical condition, making it a therapeutic device.
No
The device is intended to amplify sound for individuals with hearing impairment and to support the self-fitting and fine-tuning of a hearing aid, which are functions related to treatment/compensation rather than diagnosis of a condition.
No
The device description explicitly states that the system consists of two components: a wireless hearing aid with a self-fitting feature (Vibe SF) and a mobile web application (EasyFit). The Vibe SF wireless hearing aid hardware includes physical components like ear pieces, housing, circuit board, battery, chip, and electroacoustic components. While software is integral to the self-fitting functionality and control, the device is not solely software.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- IVD Definition: In Vitro Diagnostics are tests performed on samples taken from the human body, such as blood, urine, or tissue, to detect diseases, conditions, or infections.
- Device Function: The Vibe SF self-fitting hearing aid is a device that amplifies sound to compensate for hearing impairment. It works by processing sound from the environment and delivering it to the user's ear.
- Lack of Biological Sample Analysis: The device does not analyze any biological samples from the user. Its function is purely related to sound processing and delivery.
- Intended Use: The intended use is to amplify sound for individuals with perceived hearing impairment, not to diagnose or detect a disease or condition through the analysis of biological samples.
Therefore, the Vibe SF self-fitting hearing aid falls under the category of a medical device, specifically a hearing aid, and not an In Vitro Diagnostic.

Device Description
The Vibe SF Self-Fitting Hearing Aid ("Vibe SF") is a self-fitting air conduction hearing aid that is intended to compensate for impaired hearing and incorporates technology, including software, that allows users to program their hearing aids. This technology integrates user input with a self-fitting strategy and enables users to independently derive and customize their hearing aid fitting and settings.
The Vibe SF hearing aid is based on WSAUD's wireless hearing aid series Signia Silk 1X (regulated under 21 C.F.R. § 874.3305). However, unlike standard wireless air-conduction hearing aids, the Vibe SF is intended to be sold directly to the end-user without involvement of a hearing care professional. Briefly, the self-fitting hearing aid system consists of two components:
- a) A wireless hearing aid with a self-fitting feature (Vibe SF); and
- b) A mobile web application (EasyFit) to support the self-fitting and fine-tuning of the hearing aid.
The Vibe SF wireless hearing aid hardware includes: Ear pieces (click sleeves), housing, circuit board, battery, chip, and electroacoustic components. The subject device is fitted for bilateral use with a left and right device. Left and right hearing aids are able to communicate with each other over a magnetic inductive wireless link. The instant fit in-the-ear (ITE) style of the Vibe SF hearing aid uses Click Sleeves in 4 different sizes to couple with the ear canal. The hearing aids are marked with 'R' for right and 'L' for left, and are powered by standard (non-rechargeable) Zinc-Air batteries (size 10A). The Vibe SF hearing aid includes software that communicates with the EasyFit app to provide self-fitting functionality.
The Vibe SF is fitted by the user through the EasyFit self-fitting web application, which is run on an Internet browser on the user's mobile device (smartphone or tablet with iOS or Android operating system). The EasyFit self-fitting web application guides the user through the selffitting procedure and also allows the user to set audiological gain parameters and preferred settings on the Vibe SF Hearing Aid. In addition, a software application (app for iOS and Android) called Vibe app is available as remote control for adjusting volume during daily use.

Description of the test set, sample size, data source, and annotation protocol
WSAUD performed a pivotal clinical study to assess the patient-reported benefit from using the self-fitted Vibe SF hearing aid versus the same form factor hearing aid fitted by a hearing care professional ("HCP"). The study was designed as a Single-arm randomized crossover study with patients serving as their own control. It was blinded for some of the secondary endpoints. There was 1 study site in the United States. Patient Population: The devices were tested on 28 subjects. All subjects reported a self-perceived hearing loss, with 71.4% describing their hearing loss with having "A little trouble" and 28.6% with having "A lot of trouble." 4 of the 28 subjects were experienced hearing aid users with a mean of 33 months of hearing aid use.
Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)
Clinical Testing Summary:
Study Type: Single-arm randomized crossover study.
Sample Size: 28 subjects.
Primary Effectiveness Endpoint: To demonstrate that the Vibe self-fitting (SF) strategy is non-inferior to the audiologist-fit (HCP fit) strategy in subject's perceived hearing aid benefit after using the Vibe SF (investigational device) and Silk 1X HCP fit (comparator device) hearing aids in real-life conditions. Hearing aid benefit was measured by 3 sub-scales of the Abbreviated Profile of Hearing Aid Benefit (APHAB): ease of communication ("EC"), [ability to hear in] background noise ("BN"), and [ability to hear in] a reverberant room ("RV"). The primary endpoint result was comprised of the combined results from these subscales; success required simultaneous non-inferiority of the Vibe SF as compared to HCP fit hearing aid on all three subscales.
Primary Safety Endpoint: The safety endpoint was the rate of adverse device effects.
Key Results:
The study met the primary endpoint. The Vibe SF strategy was non-inferior to the HCP fit strategy in each of the 3 benefit scores for each subscale in the APHAB (p

Performance Data
Non-Clinical Testing Summary
Performance testing was conducted to demonstrate that the Vibe SF Self-Fitting Hearing Aid is as safe and effective as the Bose Hearing Aid. WSAUD conducted a series of non-clinical tests on the Vibe SF to assess electrical safety. EMC, wireless coexistence, electroacoustic performance, usability, biocompatibility, and software. The results are summarized in the table below:

In all instances, the Vibe SF Self-Fitting Hearing Aid functioned as intended and results observed were as expected.
As noted in the above table, a human factors validation test was performed to demonstrate that the Vibe SF can be used safely and effectively, per its labeling, by representative intended users, for the intended uses and in the intended use environments. The results indicated that any remaining residual use-related risks were acceptable and were outweighed by the benefits derived from use of the device.
Labeling mitigations were implemented on the Vibe SF box labeling and in the Vibe SF Instructions for Use ("IFU") to help potential users with the self-selection process. These included clarification of the intended users of the device, identifications in which the device may and may not be appropriate, and informing users of the device's limitations and the value of a professional hearing loss evaluation.
Clinical Testing Summary
WSAUD performed a pivotal clinical study to assess the patient-reported benefit from using the self-fitted Vibe SF hearing aid versus the same form factor hearing aid fitted by a hearing care professional ("HCP"). The study was designed as a Single-arm randomized crossover study with patients serving as their own control. It was blinded for some of the secondary endpoints. There was 1 study site in the United States.
