Short answer: the EarFun Uboom L for sound, the JBL Go 5 for durability and pairing. The Uboom L, tuned by Oluv, is the stronger-sounding pick, but latency is high at 400ms unless low latency mode brings it to 66ms, and that mode does not work when two speakers are TWS paired. The Go 5 brings an IP68 rating, up from the Go 4’s IP67, plus AirTouch tap-to-pair stereo linking, yet stays overpriced and little changed from the Go 4 besides the lights.
Buy the EarFun Uboom L ($49.79) for a medium speaker; the JBL Go 5 ($54.95) suits a small speaker instead.
Battery life favors the EarFun Uboom L: rated for 16 hours against 8 hours for the JBL Go 5.
