Short answer: the EarFun Uboom L. It ranks #2 of 177 medium speakers by sound quality, rated 4.6/5, at $49.79; the Marshall Emberton II ranks #126, rated 2.7/5, and costs $114, which makes this an easy call rather than a real tradeoff.
The Marshall Emberton II is the longer-running option. A tough waterproof speaker with Marshall styling, a very long battery and quick charging. It is rated for 30 hours of battery against 16 for the EarFun Uboom L. It links with other speakers (Marshall Stack), which the EarFun Uboom L cannot. Watch for: Strange unnatural echo-like sound coloration, bass not as deep as competitors.
The EarFun Uboom L is the better-sounding, louder pick. 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 88dB for the Marshall Emberton II. It supports AAC Bluetooth, which the Marshall Emberton II lacks. It keeps a wired aux input, which the Marshall Emberton II lacks. The catch: It cannot produce real low-bass rumble or fill a large, noisy space, and the top end loses some detail.
Buy the EarFun Uboom L. It is rated higher for sound quality than the Marshall Emberton II and costs less, so only choose the other one for a particular feature it does better.
