Extra Volume Booster

Extra Volume Booster
- Simple, small, free app to boost your speaker or headphone sound volume. Useful for movies, audio books and music.
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).
