Short answer: the JBL Flip 7, if you are buying new. The JBL Flip 4 ranks higher than the LG Xboom Grab (#81 vs #106 of 182 medium speakers) but is discontinued; its replacement, the JBL Flip 7, is rated 4.2/5 at $149.95 and is still sold new.
The JBL Flip 4 is the deeper-bass, lighter option. A compact waterproof speaker with an aux input and decent battery life. Its bass reaches about 66Hz before falling 10dB, against 75Hz for the LG Xboom Grab. At 1.1 lbs (510 g) it weighs noticeably less than the LG Xboom Grab at 1.5 lbs (680 g). It keeps a wired aux input, which the LG Xboom Grab lacks. The catch: Battery failures are common.
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 12 for the JBL Flip 4. It supports AAC Bluetooth, which the JBL Flip 4 lacks. It has an adjustable EQ, which the JBL Flip 4 lacks. The catch: Bass extension not as deep as the top speakers.
Buy the JBL Flip 7, the replacement for the discontinued JBL Flip 4; it is rated higher for sound quality than the LG Xboom Grab.
