Comments on Sound Amplifier for Android

★★★★★ Ken Davidson (KenDav73) · Jul 15, 2026

I'm going deaf in my left ear, this helps adjust the sounds levels in my earbuds to manipulate the volume levels separately.

★★★★★ Jerry Cantu · Jul 18, 2026

Works great. Is 70 years old, normally not able to hear my multimeters' continuity high pitch sound. It works great with my Waze Bluetooth headphones on and the app Boost options selected, I sat my phone next to my multimeter and can hear what I was deaf to hearing. Am cured, wonderful app, thank you, Google. 😊

★★★★★ Roland J Gutierrez · Jun 12, 2026

This app imo better than all the other apps iv used to listen I finally heard what u wanted to hear not fully ill work on that im just using to pickup ambient sounds.

★☆☆☆☆ Da N · Jun 2, 2026

This Sound Amplifier DOESN'T amplify or even acknowledge many sounds. Right now I have one earbud in, and I can NOT hear a bird outside my window using the Sound Amplifier App The ear without an earbud can hear the bird loud and clear. This only hears certain sounds. It produces static and feedback when close to other electronics it transfers its internal sounds as sounds in your environment. . It's not good at voices either. I'm sure there are far better free to use apps

★☆☆☆☆ jim smith · Jun 3, 2026

Completely useless! Doesn't work at all! Not even the slightest sound let alone any amplification! Samsung S7 - Maybe too basic a phone to work with? Update - I thought I'd give this app another go on a S10e. Unfortunately same result! Nothing! Perhaps it only works with BT earphones?

★☆☆☆☆ Rodilyn Valenzuela · Jun 11, 2026

The response was very slow. And it's not good to use for the person with hard of hearing. The sound was too noisy and mess, and you hear everything unclear and late response.
