It ranks #111 of 150 medium speakers by sound quality (rated 2.7/5); the Boat Stone 350/352/358 ranks #130 (rated 2.3/5). Both are rated below 3.0/5 among the 150 medium speakers, and the Earfun Uboom L, ranked #1 at $49.79, is a better place to start if sound quality matters.
The case for the Marshall Emberton II: 30 hour battery life: among the best in its class; a 20 min quick-charge gives 4 hours. Watch for: Strange unnatural echo-like sound coloration, bass not as deep as competitors.
The case for the Boat Stone 350/352/358: Long battery life (12 hours), IPX5 water resistant, compact and portable, sturdy build, dual passive radiators. Watch for: Some midrange peaks, treble slightly rolled off.
