Short answer: the Soundcore Boom 3i. It ranks #31 of 177 medium speakers by sound quality, rated 4.0/5, at $118.99. The LG Xboom Grab ranks #106, rated 3.0/5, at $100.98, $18.01 cheaper, which does not close the gap in sound quality.
The Soundcore Boom 3i is the better-sounding, deeper-bass pick. A warm, punchy waterproof speaker that sounds great and is a strong value. Its bass reaches about 56Hz before falling 10dB, against 75Hz for the LG Xboom Grab. The tradeoff: Not quite as good as a JBL Charge 5, doesn’t go quite as loud or sound quite as balanced, but very very close.
What the LG Xboom Grab does well: A rugged waterproof speaker with elastic mounting straps, a long 20 hour battery, multipoint pairing and app room calibration. It links with other speakers (Auracast), which the Soundcore Boom 3i cannot. Watch for: Bass extension not as deep as the top speakers.
Buy the Soundcore Boom 3i. It is rated higher for sound quality, and saving $18.01 with the LG Xboom Grab does not make up for the sound-quality gap.
