Earfun Uboom X vs Tribit Stormbox Lava (August 2026)

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 70 boombox speakers at $128; the Tribit Stormbox Lava ranks #3 of 75 large speakers at $100.

The case for the Earfun Uboom X: Tuned by Oluv and he knocked it out of the park again. Set against that: The out of the box 0.33 firmware and EQ sounds horrible.

What the Tribit Stormbox Lava gets right: Fantastic bass extension. The catch: Quite heavy for the size.

One note: the Earfun Uboom X is discontinued, but it still ranks #1 of 70 boombox speakers, ahead of most of what is still sold new, so it is worth considering used.

Buy the Earfun Uboom X at $128 if you want a boombox speaker. Buy the Tribit Stormbox Lava at $100 if you want a large speaker instead.

The Two Speakers In Full

Earfun Uboom X: $128 Discontinued Myearfun Amazon

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.

Cons: The out of the box 0.33 firmware and EQ sounds horrible. Some people have mentioned sound interruption issues when using 2 in TWS, I don’t have this issue with my Pixel 7 Pro, try disabling AAC in that case. 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

Tribit Stormbox Lava: $100 Amazon Aliexpress

Pros: Fantastic bass extension. Goes deeper than the Boom 2 as seen in the linked video of sound samples. Firmware 2.0.0 is a big improvement in neutrality.

Cons: Quite heavy for the size. Some bass boost way down low. Treble and upper mids have some peaks.

Setup: Try out the Alan Ross EQ’s at this timestamp in his video There’s also a max bass EQ from Oluv and you can turn down the lowest slider for it to be more neutral
