Brand/Manufacturer: CLARITY USA
Authorized Retailer Badge

Clarity Portable Telephone Handset Amplifier features Clarity Power technology which makes telephone conversations not only louder, but also clearer and easier to understand. It is a battery-powered phone amplifier with slide controls for both volume and tone, providing up to 40 decibels of amplification for telephone users with hearing loss. Boost button allows for even more amplification and eliminates background noise and feedback by muting the microphone in the handset. This will work with most phones with coiled cord handsets. The user will simply have to unplug the handset coiled cord from the phone and plug in the device then plug back the coiled handset cord into the amplifier. This provides a volume boost to the handset earpiece.
