What it is
Summary
AI-generated from vendor-published content · April 26, 2026
This is a small inline device that plugs between a landline phone handset and the phone base, boosting the incoming call volume significantly — up to 20 times louder than a standard phone. It's designed for someone who struggles to hear phone conversations clearly, whether due to age-related hearing loss or moderate-to-severe hearing impairment. The unit is self-contained and requires no installation beyond plugging in the two phone cords, with a slide control to adjust amplification level and a power button to conserve the 9V battery (not included). This only works with traditional wired landline phones — it won't work with cordless phone handsets, VoIP adapters, or cell phones.
