What it is
Summary
AI-generated from vendor-published content · April 26, 2026
The UA-45 is an in-line amplifier that plugs between a corded phone and its handset to boost incoming call volume by up to 45 decibels — well above standard phone output. It's designed for people with mild to severe hearing loss who want to keep using their existing corded phone rather than replacing it entirely. The unit includes tone enhancement controls so you can adjust which speech frequencies get boosted, which matters a lot for people with high-frequency hearing loss who miss consonants more than vowels. One important note: this only works with corded phones that use a standard modular handset jack — it won't work with cordless phones, cell phones, or many modern VoIP desk phones.
