RCA Symphonix Personal Sound Amplifier PSA10
Unlike other assistive listening devices that amplify all sounds, RCA Symphonix™ Personal Sound Amplifier (PSA) uses advanced HD digital technology to distinguish speech sounds from background noises, so you can hear clearly and comfortably. Symphonix is completely rechargeable, making batteries a thing of the past!
RCA Symphonix PSA10 is discreet, easy to use and fits comfortably behind the ear. Set the amount of volume reduction you need with a flip of the switch. It comes with left and right tubes, and medium and large domes, everything you need to customize Symphonix.
