Soundcore Boom 3i vs Ultimate Ears Wonderboom 3

The Soundcore Boom 3i is the better-sounding, deeper-bass pick. Looks to be designed as a direct competitor to the JBL Charge 5 with a very similar sound profile, warm tuned with boosted bass. Its bass reaches about 56Hz before falling 10dB, against 76Hz for the Ultimate Ears Wonderboom 3. It supports AAC Bluetooth, which the Ultimate Ears Wonderboom 3 lacks. It has an adjustable EQ, which the Ultimate Ears Wonderboom 3 lacks. Watch for: Not quite as good as a JBL Charge 5, doesn’t go quite as loud or sound quite as balanced, but very very close.

The Ultimate Ears Wonderboom 3 is the lighter pick. IP67 rated, floats, and is rated to survive a 5 ft drop onto hard surfaces. At 0.9 lbs (420 g) it weighs much less than the Soundcore Boom 3i at 1.7 lbs (783 g). The catch: Not stereo, barely any bass.

Buy the Soundcore Boom 3i. It is rated higher for sound quality, and the $39 you would save on the Ultimate Ears Wonderboom 3 does not close the gap.

Ultimate Ears Wonderboom 3 ranking card

Newer model: the Ultimate Ears Wonderboom 4, ranked higher, rated 2.9/5, released Jun 2024.

Older models: the Ultimate Ears Wonderboom 2 (ranked lower, rated 2.9/5) and the Ultimate Ears Wonderboom (ranked lower, rated 2.9/5). See every Ultimate Ears Wonderboom, Boom and Megaboom generation.

Pros: IP67 rated, floats, and is rated to survive a 5 ft drop onto hard surfaces. 14 hour battery: longer than the Ultimate Ears Wonderboom 2. Measured bass extension of 76Hz (-10dB).

Cons: Not stereo, barely any bass. Boosted 93Hz upper bass. Cuts bass heavily at high volume. 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 2022. Not technically a 360 speaker, only front and rear.
