Short answer: the W-King D20. It ranks #41 of 112 boombox speakers by sound quality, rated 3.6/5, at $193; the B&O Beolit 20 ranks #48, rated 3.4/5, and costs $749, so there is little reason to consider the other one.
The W-King D20 is the longer-running, tougher choice. A loud stereo party speaker with two wireless microphones, a 24 hour battery and water resistance. It is rated for 24 hours of battery against 8 for the B&O Beolit 20. It is rated IPX6 against IPX4 for the B&O Beolit 20. It plays in stereo from a single unit, unlike the B&O Beolit 20. Watch for: Rising frequency response but upper treble rolled off, 700Hz and 1.2kHz peaks.
The B&O Beolit 20 is the lighter option. A premium designer portable with 360 degree sound and a top that doubles as a wireless phone charger. At 6 lbs (2.7 kg) it weighs much less than the W-King D20 at 14.3 lbs (6.5 kg).
Buy the W-King D20. It is rated higher for sound quality than the B&O Beolit 20 and costs less, so only choose the other one for a particular feature it does better.
