WHY VOLUME BOOST + SPEAKER EQ
Most "volume booster" apps are fake. They just open the system volume slider. Volume Boost + Speaker EQ uses actual audio signal processing to amplify and enhance sound output beyond what the default volume controls provide.
No gimmicks. Real audio enhancement powered by professional EQ technology.

IMPORTANT NOTE
Audio amplification beyond manufacturer limits may cause speaker distortion at maximum levels. We recommend starting at moderate boost levels and increasing gradually. Use hearing protection with headphones at high volumes.
