Short answer: the Marshall Middleton. It ranks #33 of 120 large speakers by sound quality, rated 4.0/5, at $257.52; the B&O Beosound Level ranks #92, rated 2.8/5, and costs $2,250, which makes this an easy call rather than a real tradeoff.
The Marshall Middleton is the better-sounding, deeper-bass choice. A waterproof stereo speaker with very deep bass for its size, a long battery, a power bank and a detachable strap. Its bass reaches about 39Hz before falling 10dB, against 60Hz for the B&O Beosound Level. At 4 lbs (1.8 kg) it weighs much less than the B&O Beosound Level at 7.3 lbs (3.3 kg). It is rated IPX7 against IP54 for the B&O Beosound Level. The tradeoff: 5db dip at 1.7kHz and 6.3kHz.
The case for the B&O Beosound Level: A sculptural luxury speaker that works on battery or mains, mounts on a wall, and streams over Wi-Fi with upgradeable modules. Watch for: Not very deep bass, peaks in midrange.
Buy the Marshall Middleton. 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.
