Intended to amplify sound for individuals 18 years of age or older with perceived mild to moderate hearing impairment, Bose SoundControlTM Hearing Aids are the first FDA-cleared, self-fitting, direct-to-consumer hearing aids you can fit and tune yourself with results similar to what you would get from an audiologist. Designed to help you hear a broader range of sound, the high-quality audio helps you hear more of what you want -- even in a noisy environment. Clinically proven to provide audiologist-quality customization, CustomTuneTM technology provide users with hundreds of self-tuning options (with no pre-programming or hearing test necessary). Plus, you'll enjoy all-day comfort when worn for an average of eight hours per day. In a clinical study, people with mild to moderate hearing impairment generally experienced similar hearing benefit and were more satisfied when using Bose self-fitting technology compared with professional fitting of the same device.
