With the BassUp feature on and the EQ set to the default ‘Soundcore Signature’ preset, this speaker has a sound profile that’s remarkably similar to its predecessor, the Anker Soundcore Motion Boom Plus. As expected from a small speaker, it doesn’t reproduce too much low bass, even with BassUp enabled. Fans of genres like EDM and hip-hop will be left wanting as basslines and kicks lack boom and substance. However, the mid-range is balanced and can reproduce vocals and lead instruments in some detail. There’s a dip in the high-mid response that carries over into the treble range, though, which can render sibilants, like cymbals, a little dull and lacking in bite. That said, there’s a graphic EQ and presets accessible via the companion app that you can use to tweak the sound to your liking.
