These are not really the same size class, and that is the honest framing here. The Brane X ranks #4 of 120 large speakers by sound quality at $549; the Bose Lifestyle Ultra Speaker ranks #14 of 29 powered desktop speakers by sound quality at $279.
The Brane X is the battery-powered, tougher choice. A portable speaker with extraordinarily deep bass for its size, plus Wi-Fi, AirPlay, Alexa and a low latency aux input. Its battery is rated for 12 hours, while the Bose Lifestyle Ultra Speaker needs an outlet. It is rated IP57, while the Bose Lifestyle Ultra Speaker has no water resistance. It plays in stereo from a single unit, unlike the Bose Lifestyle Ultra Speaker. The catch: The front-facing design has only moderate dispersion, so sound changes noticeably off to the sides or behind it.
What the Bose Lifestyle Ultra Speaker does well: A compact smart speaker with an up firing driver for taller sound, built in Alexa, AirPlay 2, Google Cast and an aux input. The tradeoff: RTINGS lists sub-par directivity as its main weakness, and reviewers agree a single unit sounds narrow from side to side, so it works best as a stereo pair.
Buy the Brane X at $549 if you want a large speaker. Buy the Bose Lifestyle Ultra Speaker at $279 if you want a powered desktop speaker instead.
