These are not really the same size class, and that is the honest framing here. The Brane X ranks #4 of 83 large speakers by sound quality at $500; the Bose Lifestyle Ultra Speaker ranks #12 of 19 powered desktop speakers by sound quality at $299.
The case for the Brane X: 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. The tradeoff: 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: Three drivers (a 3in woofer and 1in tweeter facing forward, plus a 1.5in driver firing upward) give it a noticeably taller sound than most compact home speakers. 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 $500 if you want a large speaker. Buy the Bose Lifestyle Ultra Speaker at $299 if you want a powered desktop speaker instead.
Water resistance is not close: the Brane X is rated at IP57 (brief submersion), well ahead of the Bose Lifestyle Ultra Speaker at no water resistance.

The Two Speakers In Full
Brane X: $500 Amazon eBay
Pros: 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. The medium bass-boost setting is the most balanced. Measured bass extension of 31Hz (-10dB).
Cons: 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. The upper bass is boosted around 120Hz, and the robot voice announcements can be annoying.

Bose Lifestyle Ultra Speaker: $299.00 each Amazon eBay
Pros: Three drivers (a 3in woofer and 1in tweeter facing forward, plus a 1.5in driver firing upward) give it a noticeably taller sound than most compact home speakers. Stuff gave it the edge over the Sonos Era 100, and TechRadar called its tonal balance fairly neutral, with tight bass control and high detail. Alexa, including Alexa+, is built in, and RTINGS found its microphones picked up commands easily from across a noisy room. It streams over AirPlay 2, Google Cast, Spotify Connect and Bluetooth 5.3, keeps a 3.5mm aux input that the Era 100 lacks, and two units can be stereo paired or used as rear surrounds with the Lifestyle Ultra Soundbar.
Cons: 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. Deep bass is limited: Engadget found the low end restrained and preferred the Denon Home 200’s sound, Stuff noted it can’t separate sub-bass from the bassline and that DSP pulls bass back at maximum volume, and TechRadar heard a slight toothiness in the treble that needed EQ to calm. The EQ is only bass, mid and treble with no automatic room calibration. Bose warns the aux and Bluetooth inputs add lip sync delay for TV use, it has no battery or IP rating, and both SoundGuys and Engadget needed several restarts to get stereo pairing working.
