Short answer: the Soundcore Boom 3i for better sound quality, the Ultimate Ears Wonderboom 3 for the lower price. The Soundcore Boom 3i ranks #27 of 136 medium speakers at $110. The Ultimate Ears Wonderboom 3 ranks #85 at $79.99, $30.01 cheaper.
What the Soundcore Boom 3i offers: Looks to be designed as a direct competitor to the Charge 5 with a very similar sound profile, warm tuned with boosted bass. Better value for the money than the Charge 5. Watch for: Not quite as good as a Charge 5, doesn’t go quite as loud or sound quite as balanced, but very very close. An earlier firmware version had some bass distortion, update your firmware in the Soundcore App
What the Ultimate Ears Wonderboom 3 offers: IP67 rated, floats, and is rated to survive a 5 ft drop onto hard surfaces. 14 hour battery - longer than the Wonderboom 2. Watch for: 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.
Buy the Soundcore Boom 3i if sound quality is the priority over the price, or the Ultimate Ears Wonderboom 3 if the price is the priority over sound quality.
