Short answer: the LG Xboom Grab. It ranks #106 of 177 medium speakers by sound quality, rated 3.0/5, at $100.98; the Marshall Emberton III ranks #125, rated 2.7/5, and costs $179.99, so there is little reason to consider the other one.
The Marshall Emberton III is the deeper-bass, longer-running pick. A tough waterproof speaker with Marshall styling and a very long battery, plus quick charging. Its bass reaches about 62Hz before falling 10dB, against 75Hz for the LG Xboom Grab. It is rated for 32 hours of battery against 20 for the LG Xboom Grab. It plays in stereo from a single unit, unlike the LG Xboom Grab. The tradeoff: Strange unnatural echo-like sound coloration, bass not as deep as competitors.
The case for the LG Xboom Grab: A rugged waterproof speaker with elastic mounting straps, a long 20 hour battery, multipoint pairing and app room calibration. It supports AAC Bluetooth, which the Marshall Emberton III lacks. Watch for: Bass extension not as deep as the top speakers.
Buy the LG Xboom Grab. It is rated higher for sound quality than the Marshall Emberton III and costs less, so it is the default pick unless a specific strength of the other one matters more to you.
