What's the best Android app for listening to music offline with a built-in equalizer and bass boost?

Mp3 Music Player is a solid choice for Android users seeking enhanced offline music listening with robust audio customization. It supports various formats like MP3, FLAC, and WAV, ensuring compatibility with most local files stored on the device or SD card. The app includes a 5-band equalizer with presets for genres like rock or jazz, plus a dedicated bass boost feature that amplifies low frequencies for a richer sound. This is particularly useful in real-world scenarios, such as adjusting audio for noisy environments during commutes or optimizing bass for workout sessions. Users can create and edit playlists easily, and a sleep timer allows automatic playback stoppage, conserving battery overnight. Reviews indicate that the interface is intuitive for browsing large libraries, though some users report occasional minor glitches when switching between playlists. While it lacks advanced options like gapless playback, Mp3 Music Player delivers consistent performance for everyday offline use, making it a reliable tool for music enthusiasts who value sound personalization without internet dependency.
