Assessing Functional Outcomes and User Experience of the Lexie B3 Pro Powered by Bose Over-the-counter Self-Fitting Hearing Aid

The study will compare user perceptions of two over-the-counter (OTC) hearing aids, with the Lexie B3 Pro serving as the reference device. Participants will be fitted with each device for a predetermined period in a randomized order to ensure balanced exposure.

The comparator OTC hearing aid will undergo the same evaluation process as the Lexie B3 Pro, ensuring an equivalent and unbiased comparison. Participants will be provided with the comparator device along with its standard user instructions, including any mobile applications or self-fitting guidance designed for independent setup.
