EarFun UBoom X vs Tribit Stormbox Blast

Last updated: November 7, 2026

Short answer: the Tribit Stormbox Blast, if you are buying new. The EarFun Uboom X ranks higher than it (#1 vs #2 of 113 boombox speakers, 4.7/5 vs 4.5/5) but is discontinued, so only consider it used; the Tribit Stormbox Blast is still sold new at $199.99.

EarFun Uboom X vs Tribit Stormbox Blast

The UBoom X was tuned by Oluv, and it shows. Our notes call it possibly the best-sounding modern Bluetooth speaker, only slightly behind the Vifa Helsinki, with deeper bass than the Blast and the unusual trait of sounding correct at every volume level because it applies a different EQ curve per level rather than one fixed setting.

There’s one real catch: the out-of-box firmware. The 0.33 firmware and its default EQ are described in our notes as sounding horrible. You need to update it and load the tuned settings before the speaker performs the way its ranking suggests, and a small number of users report TWS interruptions that disabling AAC tends to fix.

Both are genuinely great; the UBoom X just measures better. The Blast isn’t a consolation prize. It’s the current #2 in a 113-speaker class and would be the easy recommendation if the UBoom X weren’t sitting at #1.

Buy the UBoom X if you can still find one, after updating its firmware first. Buy the Stormbox Blast if you want the same tier of performance currently in production.
