Short answer: the Soundcore Motion 300. It ranks #3 of 177 medium speakers by sound quality, rated 4.5/5, at $79.99; the LG Xboom Grab ranks #106, rated 3.0/5, and costs $100.98, which makes this an easy call rather than a real tradeoff.
The Soundcore Motion 300 is the better-sounding, deeper-bass choice. A compact stereo speaker with deep bass for its size, hi res Bluetooth and a custom EQ for each position, standing or lying down. Its bass reaches about 50Hz before falling 10dB, against 75Hz for the LG Xboom Grab. It supports LDAC Bluetooth, which the LG Xboom Grab lacks. It plays in stereo from a single unit, unlike the LG Xboom Grab. Watch for: Without the above EQ or turning the top 2 treble EQ bars to max, this speaker is very rolled off in the treble and will rank around #50 in the rankings.
The LG Xboom Grab is the longer-running choice. A rugged waterproof speaker with elastic mounting straps, a long 20 hour battery, multipoint pairing and app room calibration. It is rated for 20 hours of battery against 13 for the Soundcore Motion 300. The catch: Bass extension not as deep as the top speakers.
Buy the Soundcore Motion 300. It is rated higher for sound quality than the LG Xboom Grab and costs less, so it is the default pick unless a specific strength of the other one matters more to you.
