The Anker Soundcore 3 is passable for music. Even with its 'Bass Up' feature turned on, it struggles to reproduce the deep thump and rumble in low bass that's often present in bass-heavy music like hip-hop or EDM. However, this is normal for a small speaker. Its mid-range is relatively balanced, ensuring vocals and lead instruments sound clear. However, its underemphasized treble range can cause higher-pitched vocals and instruments to sound dull and veiled. Thankfully, its companion app features a graphic EQ and presets that can customize the speaker's sound.
