Short answer: the LG Xboom Grab. It ranks #106 of 177 medium speakers by sound quality, rated 3.0/5, at $100.98; the Ultimate Ears Boom 3 ranks #113, rated 2.9/5, and costs $132.99, which makes this an easy call rather than a real tradeoff.
The LG Xboom Grab is the deeper-bass, longer-running option. A rugged waterproof speaker with elastic mounting straps, a long 20 hour battery, multipoint pairing and app room calibration. Its bass reaches about 75Hz before falling 10dB, against 91Hz for the Ultimate Ears Boom 3. It is rated for 20 hours of battery against 15 for the Ultimate Ears Boom 3. It supports AAC Bluetooth, which the Ultimate Ears Boom 3 lacks. The tradeoff: Bass extension not as deep as the top speakers.
The case for the Ultimate Ears Boom 3: A rugged waterproof speaker that floats, with a fabric shell, a stable Bluetooth connection and PartyUp linking for many speakers. It plays in stereo from a single unit, unlike the LG Xboom Grab. The tradeoff: Not stereo, barely any bass, recessed treble.
Buy the LG Xboom Grab. It is rated higher for sound quality than the Ultimate Ears Boom 3 and costs less, so it is the default pick unless a specific strength of the other one matters more to you.
