Short answer: the JBL Boombox 4. It ranks #20 of 113 boombox speakers by sound quality (rated 4.0/5); the Teufel Boomster 4 ranks #50 (rated 3.4/5).
The JBL Boombox 4 is the better-sounding, tougher pick. An extremely loud boombox for its size with fully waterproof, dustproof build, a long battery and a flexible app EQ. It is rated IP68 against IPX5 for the Teufel Boomster 4. Watch for: Pretty overpriced for the category.
The Teufel Boomster 4 is the lighter pick. A stereo boombox with DAB+ and FM radio, a long battery, splash resistance and a remote with treble control. At 8.3 lbs (3.75 kg) it weighs noticeably less than the JBL Boombox 4 at 13.2 lbs (5.98 kg). It supports aptX HD Bluetooth, which the JBL Boombox 4 lacks. It keeps a wired aux input, which the JBL Boombox 4 lacks. The tradeoff: Side by side with the Teufel Boomster 2021 the sound barely changed, and it has a little less deep bass.
