#1 Earfun Uboom X: $128 Discontinued Myearfun Amazon 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.

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

Related speakers: Earfun Uboom 360.

How it compares: Just below it: Tribit Stormbox Blast - $72 more.
