Short answer: the Earfun Uboom L. It ranks #2 of 164 medium speakers by sound quality (rated 4.6/5) at $49.79 and is still sold new; the Minirig 2 ranks #9 (rated 4.3/5) and is discontinued, so it is only an option used.
The Earfun Uboom L is the louder, tougher pick. 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. Alan Ross Reviews measured it at 103dB at full volume, against 95dB for the Minirig 2. It is rated IP67 against Splash resistant for the Minirig 2. It plays in stereo from a single unit, unlike the Minirig 2. Watch for: It cannot produce real low-bass rumble or fill a large, noisy space, and the top end loses some detail.
The Minirig 2 is the longer-running, lighter choice. Modular, can easily attach a subwoofer. It is rated for 40 hours of battery against 16 for the Earfun Uboom L. At 1.1 lbs (488 g) it weighs noticeably less than the Earfun Uboom L at 1.4 lbs (650 g). It supports aptX Bluetooth, which the Earfun Uboom L lacks. The tradeoff: Calls itself splash resistant and has no official water rating.
Buy the Earfun Uboom L. It is rated higher for sound quality, and the Minirig 2 is discontinued, so it is only available used.

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.
