Gool Volumebooster Plus is designed to boost the volume of a wired headset and your device speakers. Whilst it will boost the main loudspeaker volume, it may not be as prominant. Please bare this in mind.Millions of people blame bad headphones for low-quality music, well put the blame where it belongs; your phone and the audio software. Gool Volumebooster Plus can fix the issue system wide. With Gool Volumebooster Plus you can boost bass, treble of your phone and if you're using our presets, you can finally experience the quality of music that you truly deserve. Being system wide, Gool Volumebooster Plus works with Google Music, Pandora, Slacker, and every other music software on your device (that doesn't have a built in EQ). Gool Volumebooster Plus might not get you the same experience that you get with those over priced headphones, but what we can promise you is that you will get music that is finally worth listening to.
