These are not really the same size class, and that is the honest framing here. The Earfun Uboom L ranks #1 of 144 medium speakers by sound quality at $49.79; the Tribit Stormbox Micro 2 ranks #1 of 47 small speakers by sound quality at $49.99.
Why pick the Earfun Uboom L: One of the strongest small-speaker values for music: reviews praise clear vocals, a natural overall balance and a genuinely convincing stereo image when two are paired. The catch: It cannot produce real low-bass rumble or fill a large, noisy space, and the top end loses some detail.
Why pick the Tribit Stormbox Micro 2: Best in class sound. Watch for: Finicky phone charging, which doesn’t usually work.
Buy the Earfun Uboom L ($49.79) for a medium speaker; the Tribit Stormbox Micro 2 ($49.99) suits a small speaker instead.

The Two Speakers In Full
Earfun Uboom L: $49.79 after coupon UBOOMLWC Amazon EarFun eBay
Pros: One of the strongest small-speaker values for music: reviews praise clear vocals, a natural overall balance and a genuinely convincing stereo image when two are paired. IP67 protection, indoor/outdoor sound modes and Video Mode make it unusually adaptable; Video Mode substantially improves lip-sync for a single speaker. Measured bass extension of 56Hz (-10dB).
Cons: It cannot produce real low-bass rumble or fill a large, noisy space, and the top end loses some detail. Low-latency Video Mode disables stereo pairing, so a two-speaker setup is not a good movie system. Firmware and app behavior have also varied over the model’s long life, and the physical controls can be easy to trigger in a bag. Latency is about 400ms by default and 66ms in Video Mode, which you enable by pressing the Bluetooth button twice.
Setup: Try setting up the Earfun App (Android or iOS) to see if that works. If not, you’ll need to flash firmware 1.2.7 to work with the app and set with Oluv’s EQ in the Earfun app which sounds the best. The instructions say that you need a USB3 cable, but most USB2 cables work just fine, try the one included with your phone. Check the current firmware version by turning it on, then pressing the power and Bluetooth buttons at the same time. To flash, turn the speaker off then hold down the Bluetooth button while plugging in the cable. To flash on a mac, see these instructions. In TWS mode, long press the outdoor button for 2 seconds to change TWS to Party mode and back.

Tribit Stormbox Micro 2: $49.99 Amazon AliExpress eBay
Newer model: the Tribit Stormbox Micro 3, rated 4.2/5.
Pros: Best in class sound. Much deeper bass than most other speakers in the size. Built in strap is super useful for attaching it to things. Very neutral. To have it aimed directly at you unclip the strap and the speaker will sit upright with a slight lean back. Measured bass extension of 65Hz (-10dB).
Cons: Finicky phone charging, which doesn’t usually work.
Setup: Use in Music EQ mode, when you switch to custom it’s not able to boost the bass properly as it is missing an EQ band that Music EQ mode uses
