Short answer: the B&O Beolit 20, if you are buying new. The Teufel Boomster 2021 measures as well as it (#51 vs #48 of 113 boombox speakers, 3.4/5 vs 3.4/5) but is discontinued, so only consider it used; the B&O Beolit 20 is still sold new at $749. The Teufel Boomster 2021’s replacement, the Teufel Boomster 4, is rated 3.4/5.
The B&O Beolit 20 is the lighter choice. 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 noticeably less than the Teufel Boomster 2021 at 8.3 lbs (3.75 kg). It has an adjustable EQ, which the Teufel Boomster 2021 lacks.
The Teufel Boomster 2021 is the longer-running, tougher option. A waterproof stereo boombox with FM radio, a long battery and stereo pairing. It is rated for 18 hours of battery against 8 for the B&O Beolit 20. It is rated IPX7 against IPX4 for the B&O Beolit 20. It plays in stereo from a single unit, unlike the B&O Beolit 20.
