Short answer: the Harman Kardon Go + Play 3, if you are buying new. The Harman Kardon Go + Play 2 ranks higher than the B&O Beolit 20 (#23 vs #48 of 113 boombox speakers) but is discontinued; its replacement, the Harman Kardon Go + Play 3, is rated 4.4/5 at $385 and is still sold new.
The Harman Kardon Go + Play 2 is the better-sounding, deeper-bass option. A stylish, light stereo speaker with good sound for moving from room to room. Its bass reaches about 40Hz before falling 10dB, against 45Hz for the B&O Beolit 20. It links with other speakers (Wireless Dual Sound), which the B&O Beolit 20 cannot. It plays in stereo from a single unit, unlike the B&O Beolit 20. The tradeoff: Not as loud as others.
The B&O Beolit 20 is the tougher choice. A premium designer portable with 360 degree sound and a top that doubles as a wireless phone charger. It is rated IPX4, while the Harman Kardon Go + Play 2 has no water resistance. It has an adjustable EQ, which the Harman Kardon Go + Play 2 lacks.
Buy the Harman Kardon Go + Play 3, the replacement for the discontinued Harman Kardon Go + Play 2; it is rated higher for sound quality than the B&O Beolit 20.
