Short answer: the W-King D10 for battery and features, the Earfun Uboom X for tuning. The D10 claims 70W RMS and 120W peak output, 106dB max volume, a 42-hour battery with power bank function and IPX6, but it has an upper bass boost and its bass is not that deep. The Oluv-tuned Uboom X at $159.99 against $84.97 needs its horrible out-of-the-box 0.33 firmware and EQ replaced.
On the Earfun Uboom X side: Tuned by Oluv and he knocked it out of the park again. The tradeoff: The out of the box 0.33 firmware and EQ sounds horrible.
The case for the W-King D10: 70W RMS output with 120W peak power, exceptional 42-hour battery life, power bank function, IPX6 waterproof, 106dB max volume. The tradeoff: Upper bass boost, bass not that deep.
Buy the W-King D10 if you want one new; the Earfun Uboom X is discontinued, so only look for it used.

The Two Speakers In Full
Earfun Uboom X: $159.99 Discontinued Myearfun 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
