Bass Booster, Equalizer & Volume Booster — three professional audio tools in one app, with no subscription and no ads, ever. Bass Booster: Equalizer Pro gives you a precision 10-band equalizer, a dedicated bass booster with distortion-free deep bass, and a volume booster that pushes quiet audio past your device's normal ceiling — all in real time, on any phone, speaker, or headphones. WORKS EVERYWHERE - Phone & tablet speakers - Bluetooth headphones & earbuds - Wired headphones (3.5mm & USB-C) - Car audio via Bluetooth or AUX PROFESSIONAL 10-BAND EQUALIZER 10 frequency bands from 31 Hz to 16 kHz. Sharpen vocals, tighten drums, tame harsh highs, or dial in the exact curve your headphones were missing out of the box. POWERFUL BASS BOOSTER Real rotary gain knobs — not sliders — give you independent control over bass and mids. A proprietary anti-clipping algorithm pushes bass deeper without going boomy or blown-out. Built for hip-hop, EDM, and rock. VOLUME BOOSTER FOR QUIET AUDIO Old recordings, quiet podcasts, low-volume videos — the volume booster safely amplifies loudness past your device's normal ceiling without distortion. SEE YOUR SOUND A full-screen, sound-reactive spectrum analyzer with switchable color palettes turns every track into a visual show. ONE-TAP PRESETS - Music — wide, energetic profile - Movie — deep low-end, clear dialogue - Podcast — voice-forward, fatigue-free FALL ASLEEP WITHOUT THE JOLT Set a 15/30/45/60-minute sleep timer and audio fades out smoothly instead of cutting off abruptly. Stop settling for factory sound. Get the equalizer, bass booster, and volume booster built for people who actually care how their music sounds.
