Short answer: the EarFun Uboom L for tuning, the Miatone Boompro for price. The Uboom L is the one Oluv tuned and it shows, though latency is high at 400ms or 66ms in low latency mode, which does not work when two speakers are TWS paired. The Boompro costs $35.99 against $49.79 but is exactly the same as the Wisetiger P3 and gives up some bass extension versus higher ranked speakers.
Buy the EarFun Uboom L. It is rated higher for sound quality, and the $13.80 saving on the Miatone Boompro is not enough to make up the difference.

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.
