Our Verdict

Bose SoundLink Flex

Anker Soundcore Motion 300

The Bose SoundLink Flex and the Anker Soundcore Motion 300 are portable Bluetooth speakers with similar designs. Depending on your listening habits, you may prefer one over the other. The Bose can reproduce more bass, which is great for genres like EDM and hip-hop. However, unlike the Anker, it has to downmix stereo content into mono to play it back. The Anker gets louder, too, with a longer-lasting battery life. Plus, its companion app has more customization tools, like a graphic EQ.
