Short answer: the W-King X20. It ranks #38 of 91 boombox speakers by sound quality (rated 3.5/5) at $219.98 and is still sold new; the Teufel Boomster 2021 ranks #46 (rated 3.4/5) and is discontinued, so it is only an option used.
The W-King X20 is the longer-running pick. It is rated for 24 hours of battery against 18 for the Teufel Boomster 2021. It has an adjustable EQ, which the Teufel Boomster 2021 lacks. Watch for: Rising frequency response but upper treble rolled off, 700Hz and 1.2kHz peaks.
The Teufel Boomster 2021 is the lighter option. At 8.3 lbs (3.75 kg) it weighs much less than the W-King X20 at 15.9 lbs (7.2 kg).
Buy the W-King X20. It is rated higher for sound quality and still sold new, while the Teufel Boomster 2021 is discontinued.
