Sound Equalizer: Bass Booster

Sound Equalizer is a free 12-band equalizer with bass booster, volume booster, virtualizer and reverb. No ads, no account, no data collected. Make music, videos, games and podcasts sound richer, louder and clearer on headphones, earbuds, Bluetooth speakers, car audio or your phone speaker.

Switch it on, pick a preset and hear the difference straight away. No audio expertise needed.

🎚️ 12-BAND EQUALIZER WITH EDITABLE FREQUENCIES
Most music equalizer apps give you 5 or 10 bands. Sound Equalizer gives you 12, from deep sub-bass to bright treble, and you can edit the frequency of each band. Lift the lows for punch, raise the mids for clearer vocals, or boost the highs for crisp detail. Changes apply in real time.

🔊 BASS BOOSTER
Add deep, powerful bass to EDM, hip-hop, pop and movie soundtracks. Adjust the bass boost strength to suit your headphones or speaker, so you get heavy bass without distortion.

📢 VOLUME BOOSTER & SOUND AMPLIFIER
Is your audio too quiet? Use the volume booster to raise the output for soft recordings, quiet videos, podcasts or a small phone speaker. Increase the level gradually for the cleanest sound.

🎧 VIRTUALIZER & REVERB
Widen the stereo image with the 3D surround virtualizer and add space and atmosphere with reverb. Great for headphones, movies and gaming.

🎛️ EQUALIZER PRESETS & UNLIMITED CUSTOM PROFILES
Choose from built-in equalizer presets: Rock, Pop, Jazz, Classical, Hip-Hop, Dance, Vocal, Bass Boost and Treble Boost. Create, rename and edit unlimited custom presets of your own.

🔗 AUTO CONNECT & AUTO APPLY
Set a sound profile for each device: Bluetooth headphones, wireless earbuds, car speaker or wired headset. Sound Equalizer applies the right profile automatically when the device connects and restores your settings every time you start listening.

🎨 THEMES & COLORS
Pick Light, Dark or AMOLED black, and change the colors to match your mood. Clean Material Design interface.
