What it is

Summary

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

This small in-line amplifier connects to a landline phone and makes the caller's voice louder, up to 20 times, using a slide control you adjust as you talk. It's meant for someone who finds a regular phone too quiet, including older adults. A power button lets you switch it off between calls to save the 9V battery, and a light tells you when the battery is running low. The battery isn't included, so plan to pick one up. It's built for landline phones, so it won't help with a cell phone call.
