Short answer: the Bugani Brief Pro. It ranks #28 of 113 boombox speakers by sound quality (rated 3.8/5); the Teufel Boomster 4 ranks #50 (rated 3.4/5).
Listeners split in a side by side sound test. Some found the Brief Pro crisper and punchier at lower volumes; others found the Boomster 4 warmer with deeper bass at higher volume and a wider stereo image from its three-way layout.
Both have weak spots at volume: the Brief Pro turns harsh and loses bass near max, and the Boomster 4 loses bass at full volume too.
Features favor the Teufel: DAB+ and FM radio, a treble control with a remote, IPX5, aptX HD and a claimed 23 hours. The Brief Pro claims 12 hours and costs much less.
Buy the Bugani Brief Pro. It is rated higher for sound quality than the Teufel Boomster 4.
