Short answer: the Brane X. It ranks #4 of 105 large speakers by sound quality, rated 4.6/5, at $549; the B&O Beosound Level ranks #86, rated 2.8/5, and costs $2,250, so there is little reason to consider the other one.
The B&O Beosound Level is the longer-running pick. Premium Scandinavian design with elegant domestic sculpture aesthetic. It is rated for 16 hours of battery against 12 for the Brane X. The tradeoff: Not very deep bass, peaks in midrange.
The Brane X is the better-sounding, deeper-bass 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 60Hz for the B&O Beosound Level. It is rated IP57 against IP54 for the B&O Beosound Level. It supports aptX HD Bluetooth, which the B&O Beosound Level lacks. The catch: The front-facing design has only moderate dispersion, so sound changes noticeably off to the sides or behind it.
Buy the Brane X. It is rated higher for sound quality than the B&O Beosound Level and costs less, which makes it the one to get unless you need something the other one does better.
