Short answer: the Soundcore Boom 2 Plus, if you are buying new. The EarFun Uboom X ranks higher than it (#1 vs #36 of 91 boombox speakers, 4.7/5 vs 3.6/5) but is discontinued, so only consider it used; the Soundcore Boom 2 Plus is still sold new at $179.99.
The EarFun Uboom X is the better-sounding, longer-running option. Tuned by Oluv and he knocked it out of the park again. It is rated for 30 hours of battery against 20 for the Soundcore Boom 2 Plus. The catch: The out of the box 0.33 firmware and EQ sounds horrible.
The case for the Soundcore Boom 2 Plus: Quite a bit lighter than most of the other boombox size speakers. The tradeoff: Warm tuning meaning a rolled off treble and some upper bass boost.
Buy the Soundcore Boom 2 Plus new; the EarFun Uboom X is no longer sold new, so it only makes sense as a used find.

The Two Speakers In Full
EarFun Uboom X: $159.99 Discontinued eBay
Pros: Tuned by Oluv and he knocked it out of the park again. Deeper bass than the Tribit Stormbox Blast. Extremely neutral, possibly the best of any modern Bluetooth speaker slightly behind the Vifa Helsinki. This is the only speaker that sounds correct at every single volume level due to Oluv’s individual EQ settings at each volume level. Other speakers will need a different EQ at each volume level. Amazing sounding at low levels as it boosts bass and treble at low levels to account for the equal-loudness contour. Just considering the midrange and treble, this speaker is better sounding than the EarFun Uboom L. Measured bass extension of ~38Hz (-10dB).
Cons: The out of the box 0.33 firmware and EQ sounds horrible. Some users have reported sound interruption issues when running two in TWS, though not on every source device, and disabling AAC resolves it where it occurs. Discontinued.
Setup: Please update it using the Earfun app (Android or iOS) and select an Oluv EQ. The Earfun app has sound profiles created by Oluv for Studio, Indoor, Indoor+, Outdoor, Outdoor+, BOOM xxX, and Ground 0 which are all fantastic. Oluv has a newer firmware pack that brings it up a few more notches of neutral

Soundcore Boom 2 Plus: $179.99 Amazon eBay
Older model: the Soundcore Motion Boom+ (ranked lower, rated 2.9/5). See every Soundcore Boom generation.
Same family: the Soundcore Boom 2 (smaller model, rated 4.5/5).
Pros: Quite a bit lighter than most of the other boombox size speakers. This speaker will likely move up as we get a good EQ tune that makes it a lot more neutral. Measured bass extension of 39Hz (-10dB).
Cons: Warm tuning meaning a rolled off treble and some upper bass boost. Reasonably deep bass, but not as good as the top ranked.
