Comments on Sound Amplifier for Android

★★★★★ 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. 😊

★★★★★ 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.
