About this app

Volume Booster - Sound Booster is a free volume amplifier that turns weak phone audio into rich, loud sound. If your music, videos or calls feel too quiet, this volume booster app pushes your Android up to 200% beyond the standard ceiling — instantly louder, with cleaner output. Designed as a true sound booster and audio enhancer for everyday listening, it works with your phone speaker, wired headphones, earbuds and Bluetooth speakers. Download the volume booster free and feel the difference on the first track.

Make Phone Louder with One Tap
Tap once and the volume booster lifts media volume, ringtones, alarms and notifications across the whole system. Use it as a music volume booster for MP3 and streaming, a video volume booster for MP4 and MKV files, a call volume booster for voice clarity in noisy places, or a ringtone booster so you never miss a call. This volume amplifier handles every media type and every output, giving you a single sound control app instead of juggling separate volume up tools.

5-Band Equalizer and Deep Bass Booster
Fine-tune your audio with the built-in music equalizer and bass booster. The sound equalizer ships with presets for Pop, Rock, Jazz, Classical, Hip-Hop, Electronic and Vocal, plus a custom 5-band EQ for full control over bass, treble and mid frequencies. The deep bass booster lifts low-end without distortion, perfect for hip-hop, EDM and movie soundtracks. Pair the bass enhancer with the volume booster and you get richer sound, harder bass and louder volume — without the muddy mix cheap booster apps leave behind.

Speaker Booster, Headphone Booster and Bluetooth Booster
The audio amplifier works everywhere you listen. As a speaker booster it pushes phone-speaker output for podcasts and audiobooks on the go. As a headphone booster it amplifies sound through wired headphones and earbuds without clipping. As a Bluetooth volume booster it lifts the level on connected speakers and headsets when their max feels too soft. One volume booster app, every output — phone speaker, headphone, earphone, Bluetooth speaker.

Sound Enhancer for Music, Movies and Calls
This sound enhancer optimizes audio quality across media. The deep bass booster delivers cinematic low frequencies for movies and music. The media volume booster improves MP4, MKV and MP3 playback. The call volume booster pulls voice forward for clearer phone calls in noisy rooms or on public transport. The video volume booster gives YouTube, Netflix and short-form clips cinematic punch. Use this audio volume booster as a complete sound control hub for every app on your phone.

Hearing Protection Built-In
Loud isn't useful if it damages your ears. Volume Booster - Sound Booster tracks your daily exposure above 85 dB and warns you when you've crossed the WHO safe-listening window. The Speaker Care suite scans for speaker distortion and helps clean your phone speaker so output stays crisp. You get louder sound and smarter sound — together.

Ratings and reviews

this is excellent and probably the best of the best apps out there that i can use to give my oppo f11 music player an edge in sounds and music loudness and talk about clarity and crystal clear wholeness of the sound and volume amped by this app!!!! love you guys!!! keep up the excellent work!!!!! =)

Simple to use. Great , clear amplified sound .. loud. As long it stays in place while I am on Spotify etc. .I'll be extremely happy. Said "Free". And it is. Beautiful.

Boosts great 👍. Be careful & turn your device volume on low before turning boost up. Anything above NORMAL on the dial is enough to blow your phone speaker. Still, put phone volume low & feel it out from there.⭐⭐⭐⭐🌟💫
