Short answer: the Bogasing G4 on battery life, the EarFun Uboom L on price. The Uboom L was tuned by Oluv and he knocked it out of the park at $49.79 against the G4’s $42.49, but latency is high at 400ms unless low latency mode is on, and that mode does not work when two speakers are TWS paired. The G4 answers with clear sound, punchy bass, an exceptional 24 hour battery and IPX7 waterproofing, though some boosted treble is wavy up top.
Buy the EarFun Uboom L. It is rated higher for sound quality, and the $7.30 saving on the Bogasing G4 is not enough to make up the difference.
There is a real battery-life gap here: the Bogasing G4 is rated for 24 hours, the EarFun Uboom L only 16 hours.
