Short answer: the JBL Boombox 4. It ranks #17 of 73 boombox speakers by sound quality; the Teufel Boomster 2021 ranks #33.

What the JBL Boombox 4 gets right: Pretty insane output capability for the size. The catch: Pretty overpriced for the category. Better than the Boombox 3 mostly because there are more 7 EQ bands instead of just 3 and it can be better tuned.

On the Teufel Boomster 2021 side: Pretty balanced sound, slightly warm. Set against that: Not as deep of bass as above ranked speakers. Boosted mid bass compensating for the lack of bass extension.

Buy the JBL Boombox 4 if sound quality matters more than the price. Buy the Teufel Boomster 2021 if the price matters more than sound quality.

If battery life is a priority, the JBL Boombox 4 is rated for 28 hours versus 18 hours for the Teufel Boomster 2021.

Pros: Pretty insane output capability for the size.

Cons: Pretty overpriced for the category. Better than the Boombox 3 mostly because there are more 7 EQ bands instead of just 3 and it can be better tuned. Try Oluv’s EQ for it. Out of the box sounds worse than the Boombox 3. No Aux input.
