Short answer: the Earfun Uboom L, narrowly. They cost about the same, $49.79 and $49.99, and the Oluv-tuned Uboom L is the stronger pick, though latency runs 400ms or 66ms in low latency mode, which fails when two speakers are TWS paired. The Miniroll counters with good clarity and detail in the mids and highs plus a warmer balance than most ultra-portables its size, though its bass is not as deep as the best.
What the Earfun Uboom L gets right: Tuned by Oluv and he knocked it out of the park. Set against that: Latency is high (400ms) without turning on low latency mode (66ms) which doesn’t work when two speakers are TWS paired.
On the Ultimate Ears Miniroll side: Good clarity and detail in the mids/highs with a warmer tonal balance than most ultra-portables its size. The tradeoff: Bass not quite as deep as the best rated speakers.
Buy the Earfun Uboom L ($49.79) for a medium speaker; the Ultimate Ears Miniroll ($49.99) suits a small speaker instead.

The Two Speakers In Full
Earfun Uboom L: $49.79 after coupon UBOOMLWC Amazon Myearfun 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.
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.
