Short answer: the EarFun Uboom L. It ranks #2 of 177 medium speakers by sound quality, rated 4.6/5, at $49.79; the Bogasing M5 ranks #61, rated 3.5/5, and costs $52.99, so there is not much of a tradeoff to weigh.
The EarFun Uboom L is the better-sounding, louder option. A great value medium speaker with clear, natural sound, waterproofing, and a Video Mode that keeps audio in sync with video. Alan Ross Reviews measured it at 103dB at full volume, against 96dB for the Bogasing M5. It plays in stereo from a single unit, unlike the Bogasing M5. The catch: It cannot produce real low-bass rumble or fill a large, noisy space, and the top end loses some detail.
The Bogasing M5 is the longer-running pick. A compact, backpack friendly speaker with very long battery life and USB-C charging at a budget price. It is rated for 30 hours of battery against 16 for the EarFun Uboom L. Watch for: Front/rear driver configuration.
Buy the EarFun Uboom L. It is rated higher for sound quality than the Bogasing M5 and costs less, so it is the default pick unless a specific strength of the other one matters more to you.
