There's a button on the speaker to activate bass boost.

You can tweak the sound profile (with EQ settings) and upgrade the speaker's firmware in Anker's Soundcore companion app for iOS and Android. I was impressed with the sound quality, which measures up well against a few more expensive - and some larger - speakers on this list. It's also IP67 waterproof and dust-proof and floats if you happen to drop it in a body of water. Battery life is rated for 20 hours at moderate volume levels. Weighing 5.29 pounds (almost a pound more than the Motion Boom), it uses Bluetooth 5.3 and is equipped with upgraded dual 3.5-inch woofers and newly added dual 1-inch tweeters, delivering up to 80 watts of audio output (60W for the woofers and 20W for the tweeters). It's easily one of the best new Bluetooth speakers of 2022. But the new-for-2022 Motion Boom Plus is significantly improved, particularly in terms of sound quality. Anker's original Soundcore Motion Boom speaker (see below) has been on this list for a while and is still a decent value at a little more than $100.
