Different classes, so treat this as a step-up-or-not question rather than a head-to-head. The Earfun Uboom X ranks #1 of 91 boombox speakers by sound quality at $159.99; the Earfun Uboom 360 ranks #34 of 164 medium speakers by sound quality at $42.
The Earfun Uboom X is the louder, deeper-bass option. Tuned by Oluv and he knocked it out of the park again. Its bass reaches about 38Hz before falling 10dB, against 61Hz for the Earfun Uboom 360. Alan Ross Reviews measured it at 110dB at full volume, against 100dB for the Earfun Uboom 360. It is rated for 30 hours of battery against 16 for the Earfun Uboom 360. Watch for: The out of the box 0.33 firmware and EQ sounds horrible.
The Earfun Uboom 360 is the lighter choice. Similar to the Maxsound Plus in sound, likely uses the same drivers. At 1.3 lbs (585 g) it weighs much less than the Earfun Uboom X at 9 lbs (4.1 kg). Watch for: Slightly rolled off treble, not as deep of bass as the best in category.
One note: the Earfun Uboom X is no longer sold new, but at #1 of 91 boombox speakers by sound quality it still outranks most current models, so used is worth considering.
Buy the Earfun Uboom X ($159.99) for a boombox speaker; the Earfun Uboom 360 ($42) suits a medium speaker instead.

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 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

Earfun Uboom 360: $42 Discontinued eBay
Pros: Similar to the Maxsound Plus in sound, likely uses the same drivers. Likely the best 360 speaker. Measured bass extension of 61Hz (-10dB).
Cons: Not stereo. Slightly rolled off treble, not as deep of bass as the best in category. Outdoor mode is more flat, indoor mode boosts bass. Not technically a 360 speaker, only front and rear. Discontinued and no longer sold new.
