Speaker Boost - Volume Booster

Offers in-app purchases

Simple, small, free app to boost your speaker sound volume. Useful as a volume booster for movies, audio books and music. Also works great as a sound booster for headphones.

USE AT YOUR OWN RISK. Playing audio at high volumes, especially for a prolonged amount of time, can destroy speakers and/or damage hearing. Some users HAVE reported destroyed speakers and earphones. IF YOU HEAR DISTORTED AUDIO, LOWER THE VOLUME (but it may be too late).

By installing this application you agree that you will not hold its developer responsible for any damage to hardware or hearing, and you are using it AT YOUR OWN RISK. Consider this to be EXPERIMENTAL software.

This is the most reliable volume booster for android but not all devices support this software. Try the amp AT YOUR OWN RISK and see if yours works.

NOTE 1: This app does not work on most Android 4.2.1-4.3 devices. It should work on Android 4.4 and higher, as well as on devices below 4.2.1.

NOTE 2: This is NOT for adjusting the speakerphone volume in phone calls (that has its own boost, I think), but for adjusting the volume of music, movies and apps.

NOTE 3: When you set the boost to zero, Speaker Boost will be off. The notification icon is just for ease of launching. If you don't like seeing the notification icon when Speaker Boost is off, just open Speaker Boost and click to close the app.
