Short answer: the JBL Boombox 3. It ranks #27 of 113 boombox speakers by sound quality (rated 3.8/5); the Teufel Boomster 4 ranks #50 (rated 3.4/5).
The JBL Boombox 3 is the better-sounding, tougher choice. A loud, fully waterproof boombox with a dedicated subwoofer, a 24 hour battery and power bank charging. It is rated IP67 against IPX5 for the Teufel Boomster 4. Watch for: Dips in mid bass range which makes the bass sound undefined, bass boosted, peaky at 700Hz, not quite as good mids and treble as the Blast.
The Teufel Boomster 4 is the lighter option. 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 much less than the JBL Boombox 3 at 14.8 lbs (6.7 kg). It supports aptX HD Bluetooth, which the JBL Boombox 3 lacks. It has an adjustable EQ, which the JBL Boombox 3 lacks. The tradeoff: Side by side with the Teufel Boomster 2021 the sound barely changed, and it has a little less deep bass.
Buy the JBL Boombox 3. It is rated higher for sound quality than the Teufel Boomster 4.
