Short answer: the Brane X on measured sound quality, the LG Xboom Bounce on price. The Brane X ranks #4 of 115 large speakers, rated 4.6/5, at $549. The LG Xboom Bounce ranks #33, rated 4.0/5, at $103.17, $445.83 cheaper.
The Brane X is the better-sounding, deeper-bass option. A portable speaker with extraordinarily deep bass for its size, plus Wi-Fi, AirPlay, Alexa and a low latency aux input. Its bass reaches about 31Hz before falling 10dB, against 54Hz for the LG Xboom Bounce. It supports aptX HD Bluetooth, which the LG Xboom Bounce lacks. It streams over Wi-Fi as well as Bluetooth, which the LG Xboom Bounce cannot. The tradeoff: The front-facing design has only moderate dispersion, so sound changes noticeably off to the sides or behind it.
The LG Xboom Bounce is the longer-running, lighter choice. A tough, waterproof speaker that survives drops and extreme temperatures, with a long battery and multipoint pairing. It is rated for 30 hours of battery against 12 for the Brane X. At 2.9 lbs (1.32 kg) it weighs much less than the Brane X at 7.7 lbs (3.5 kg). The tradeoff: Bass extension not as deep as the top speakers.
Buy the Brane X when sound quality outweighs the price for you, and the LG Xboom Bounce when the price outweighs sound quality instead.
