Efficacy and Effectiveness of an Investigational Behind-the-Ear Hearing Device Kit

The goal of this clinical trial is to learn if Sonova's rechargeable behind-the-ear hearing device kit works to treat hearing loss in adults. The main questions it aims to answer are: * Does the rechargeable behind-the-ear hearing device kit address challenging listening situations identified by participants while providing a satisfactory user experience? * Does the rechargeable behind-the-ear hearing device kit improve speech understanding in noise in a lab setting? Researchers will compare participants' performance with the rechargeable behind-the-ear hearing device kit to the unaided condition to see if it works to treat hearing loss. The rechargeable behind-the-ear hearing device kit will be subjectively compared to their personal hearing device experience. Participants will: * Use the rechargeable behind-the-ear hearing device kit for approximately 2 weeks. * Visit the clinic for the initial fitting and follow-up testing at the end of the study. Additional study visits may take place, as needed. * Complete questionnaires to identify challenging listening situations and provide feedback on their experience with the devices. * Complete lab testing to assess speech intelligibility in the presence of background noise and provide subjective feedback on features in the Mobile application.
