🎚️ 10-Band Equalizer for Android
A true 10-band equalizer with 5, 7, 10, 12, 15, or 31 band modes — far beyond a basic 10-band EQ. Fine-tune every frequency — booming subwoofer bass, crystal-clear treble, balanced sound. Custom presets for Rock, Pop, Jazz, EDM, Classical, Hip-Hop, and more.

🔊 Bass Booster & Bass Boost — Feel Every Beat
Echo's professional bass boost lifts low frequencies without distortion. The eq bass booster and subwoofer bass booster work on headphones, Bluetooth speakers, car audio, subwoofers, and phone speakers — deep, punchy bass and extra bass everywhere.

📈 Volume Booster, Sound Booster & Loudness Booster
Boost quiet audio safely with a built-in Volume Booster, Sound Booster, and Loudness Booster — no clipping. Echo works as a Headphone Volume Booster, Headphone Booster, Bluetooth Volume Booster, and Speaker Booster in one. Make your speaker and headphones louder for quiet videos and podcasts — a real equalizer sound booster for music, movies and games. A loudness booster, headphone volume booster and eq bass booster — without distortion.

📱 Works With Spotify, YouTube Music & Every App
Unlike built-in equalizers, Echo applies system-wide. Use it as a Spotify equalizer, YouTube Music equalizer, YouTube or TikTok equalizer, or with VLC, Poweramp, Apple Music, Tidal, Amazon Music, and any local player. No root required.

🚗 Android Auto, Bluetooth & Car Audio Support
Echo works with Android Auto, Bluetooth headphones and speakers, car audio and home theater. The car equalizer tunes sound for in-vehicle listening; the Bluetooth equalizer remembers your preset per device. Auto-Switching applies your saved mixes on connect. The 3D Virtualizer and surround sound equalizer turn stereo into room-filling surround sound.

🎛️ Advanced Limiter & Compressor
An advanced limiter and multiband compressor prevent distortion at high volumes. Studio-grade sound for audiophiles.

👂 Ear Tune & Safe Hearing — Personalized Sound
Take a 60-second hearing test and Echo builds your hearing profile, then tunes itself to what you actually hear — a personalized equalizer that mutes the frequencies your ears miss for a cleaner signal. Safe Hearing eases high frequencies on long, loud sessions to cut listening fatigue. Sound personalization, not a medical ear test.

Ad-free. Fully unlocked core features: 10-Band Equalizer, Bass Booster, Volume Booster, Sound Booster, and the free ear test. Material You theming. Pro adds Auto EQ, the limiter, compressor, parametric EQ, 15/31-band modes, one-tap Quick Tile, and home-screen shortcuts.

🎚️ More Than a 10 Band Equalizer
Echo is a full graphic equalizer and audio enhancer in one. Use the preamp to set gain, then shape a true 10 band equalizer curve — an equalizer for Android with an FxSound- and Poweramp-style feel. The treble booster sharpens highs, the x bass booster and epicenter bass add low-end punch, and 8D audio widens the stage.

Ratings and reviews

So far this has been a very useful app for me. There is a good amount of options to choose from, it has up to 12 bar sliders for an EQ if wanted. It enables you the option to choose how many sliders you want on an EQ. There really aren't a bunch of adds to deal with, which is awesome. If this continues I will donate to the Dev...Edited : so I noticed that ads are now being shown. Booooo! I was going to donate..

Paywall-less, totally functional, and performs simply enough while also drastically changing and improving equalizer dynamics, no matter what device or sound system you use it from. This is saying a lot, but I think this is the best amplification/bass boost app out there. I have paid for and tried them all, and they really nailed it. My reviews are free and unsolicited.

Likening this app after a couple of days. How do you save a Custom EQ setting we create? As note, trying to make fine adjustments to each band is difficult, would be nice if you could zoom in or a pop up of the number field. Also, the EQ will not work with a with a Car with built in wireless Android Auto, connection via WiFi any chance of getting that working?
