Short answer: the Bogasing S8 Pro Max. It ranks #24 of 105 large speakers by sound quality, rated 4.2/5, at $168.99; the JBL Xtreme 4 ranks #44, rated 3.8/5, and costs $309.95, so there is not much of a tradeoff to weigh.
The Bogasing S8 Pro Max is the better-sounding, lighter option. A true three way stereo design in an aluminium body: a 70mm woofer, two 52mm midrange drivers and two 31mm silk tweeters angled outward, backed by two 80mm passive radiators. At 3.4 lbs (1.55 kg) it weighs noticeably less than the JBL Xtreme 4 at 4.6 lbs (2.1 kg). It keeps a wired aux input, which the JBL Xtreme 4 lacks. The tradeoff: Its tuning is bright: the 3D mode pushes the mids and treble hard, can sound sharp or tiring at higher volumes, and sometimes adds an echo effect to vocals.
Why pick the JBL Xtreme 4: A rugged 4.6 lbs (2.1 kg) portable with IP67 protection, a replaceable battery, USB-C power-bank output, Auracast, stereo pairing and a useful 5-band app EQ. It has an adjustable EQ, which the Bogasing S8 Pro Max lacks. The tradeoff: It cannot produce the deep rumble of a larger speaker, and bass compression increases near maximum volume.
Buy the Bogasing S8 Pro Max. It is rated higher for sound quality than the JBL Xtreme 4 and costs less, so it is the default pick unless a specific strength of the other one matters more to you.
