Different classes, so treat this as a step-up-or-not question rather than a head-to-head. The B&O Beosound 2 ranks #7 of 10 powered desktop speakers by sound quality at $4,000; the Brane X ranks #4 of 102 large speakers by sound quality at $500.
The case for the B&O Beosound 2: A beautifully made, compact Wi-Fi speaker with omnidirectional playback, Chromecast, AirPlay, Bluetooth with AAC/aptX, optical and aux inputs, app EQ, voice control and Beolink multiroom. It has an adjustable EQ, which the Brane X lacks. The catch: Its bass-forward balance can recess the mids, and its 94dB maximum level is modest for a speaker intended to fill larger spaces.
The Brane X is the deeper-bass, battery-powered option. The Brane X pairs a dedicated RAD subwoofer with two midrange drivers and two tweeters to achieve extraordinary low bass for a 7.7 lbs (3.5 kg) portable: its measured -10dB extension is 31Hz. Its bass reaches about 31Hz before falling 10dB, against 45Hz for the B&O Beosound 2. Its battery is rated for 12 hours, while the B&O Beosound 2 needs an outlet. It supports aptX HD Bluetooth, which the B&O Beosound 2 lacks. Watch for: The front-facing design has only moderate dispersion, so sound changes noticeably off to the sides or behind it.
Buy the B&O Beosound 2 ($4,000) for a powered desktop speaker; the Brane X ($500) suits a large speaker instead.

The Two Speakers In Full
B&O Beosound 2: $4,000.00 each Amazon eBay
Same family: the B&O Beosound 1 (smaller model, rated 3.5/5).
Pros: A beautifully made, compact Wi-Fi speaker with omnidirectional playback, Chromecast, AirPlay, Bluetooth with AAC/aptX, optical and aux inputs, app EQ, voice control and Beolink multiroom. Reviews praise its even scaling at low volume, spacious room-filling presentation and convincing bass for a single 4.1kg enclosure. Measured bass extension of ~45Hz (-10dB).
Cons: Its bass-forward balance can recess the mids, and its 94dB maximum level is modest for a speaker intended to fill larger spaces. There is no battery or water rating, so this is a mains-powered indoor product; its luxury design and streaming feature set matter more than outright value or neutral hi-fi accuracy.

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.
