Short answer: the Brane X on measured sound quality, the LG Xboom Bounce on price. The Brane X ranks #4 of 78 large speakers at $500. The LG Xboom Bounce ranks #30 at $118.08, $381.92 cheaper.
What the Brane X offers: The Brane X pairs a dedicated RAD subwoofer with two midrange drivers and two tweeters to achieve extraordinary low bass for a 3.5kg portable: its measured -10dB extension is 31Hz. Independent testing finds it loud, with well-balanced mids, a smooth treble balance and useful bass-level controls; Wi-Fi, AirPlay, Alexa, quality Bluetooth codecs and low-latency aux pass-through make it unusually versatile. Watch for: The front-facing design has only moderate dispersion, so sound changes noticeably off to the sides or behind it. Bass response shifts at maximum volume, the default aux mode has very high latency, and some listeners find the upper register edgy or need EQ to achieve their preferred balance. Its claimed 12-hour runtime and premium cost make it more of a compact high-end system than a carefree all-day speaker.
What the LG Xboom Bounce offers: Unique spherical design. Up to 30 hours battery at 50% volume. IP67 + MIL-STD-810H military certification for impact/vibration/temperature. Multipoint pairing stays connected to two devices. LED lights add flair. Watch for: Bass extension not as deep as the top speakers. Overpriced. This may move around in the rankings as we get better sound samples
Buy the Brane X when sound quality outweighs the price for you, and the LG Xboom Bounce when the price outweighs sound quality instead.
There is a real battery-life gap here: the LG Xboom Bounce is rated for 30 hours, the Brane X only 12 hours.
