Short answer: the EarFun Uboom L on value, the Minirig 4 for modular bass. The Uboom L is the Oluv-tuned pick at $49.79 against the Minirig 4’s $229.95, a $180.16 gap, though latency is high at 400ms or 66ms in low latency mode, which does not work when two speakers are TWS paired. The Minirig 4 is modular and can easily attach a subwoofer, but calls itself splash resistant with no official water rating.
Buy the EarFun Uboom L. It is rated higher for sound quality than the Minirig 4 and costs less, which makes it the one to get unless you need something the other one does better.
Battery life favors the Minirig 4: rated for 30 hours against 16 hours for the EarFun Uboom L.
There is a real gap in water resistance: the EarFun Uboom L at IP67 (brief submersion) against the Minirig 4, which has Splash resistant (splashing).
