Description

From the listing uploaded by “appupdater”.

Need a little boost ? Sound Boost increase the maximum volume from the headset, to play music, videos, podcasts... louder ! No root required ! What this application does ? Once you plug in a headset, the sound is switched from the music channel to the voice channel. The effect is different, depending on the device and the rom you use. On some devices, the sound is increased, on some others, nothing happens, or the sound is decreased. The sound could also become mono or every sound enhancement process could be disabled. So before complaining, please note that sadly, there's not much I can do to make this app work on your device. This application won't harm your device. Disabling or uninstalling it always goes back to normal.
