Soundcore Motion 100 ranking card

Same family: the Soundcore Motion 300 (larger model, ranked higher, rated 4.5/5), the Soundcore Motion X500 (larger model, rated 4.1/5) and the Soundcore Motion X600 (larger model, rated 4.3/5). See every Soundcore Motion generation.

Pros: Use Oluv’s EQ for the flattest response. Measured bass extension of 65Hz (-10dB).

Cons: Not very deep bass, slight distortion. Real-world battery falls well short of the 12-hour claim at higher volumes (closer to 4 hours at max). Charging takes about 5 hours; no charge-out for other devices. Discontinued and no longer sold new.

Ultimate Ears Megaboom 3 ranking card

Newer model: the Ultimate Ears Megaboom 4, ranked lower, rated 2.1/5, released Jun 2024. See every Ultimate Ears Wonderboom, Boom and Megaboom generation.

Pros: IP67 rated, floats, and survives drops from up to 1 meter. 20 hour battery life: about double most speakers this size. Measured bass extension of 70Hz (-10dB).

Cons: Not stereo, barely any bass. You can tell from the micro USB that they are just feeding you the same crap hardware over and over, this is inexcusable for a product released in 2018. Not technically a 360 speaker, only front and rear.
