Price is what the vendor listed when last checked. Confirm it with the vendor before buying.

Setup with instructions The amplifier is not a standalone phone. It has to be wired into an existing business phone, and the cable connections need to be right. Written instructions are enough for a family member or coworker to do this and get good results in under an hour. Tuning the tone and volume takes a little trial and error, but no clinical assessment is needed.

What it is

Summary

AI-generated from vendor-published content · October 1, 2026

The UA-50 connects to a business phone and makes the incoming voice louder, up to 170 times, through the handset or a headset. It gives 45dB of amplification and has a tone control, so you can shape the sound to what you hear best. Digital sound processing cuts distortion, echo, and static, and automatic gain control keeps the volume comfortable from call to call. It works with virtually all business phones and with any headset that has an RJ9 plug. An AC adapter is included, and a 9V battery is optional. This is a good fit for someone who has trouble hearing callers on a desk phone at work.
