Short answer: the JBL Boombox 3. It ranks #26 of 89 boombox speakers by sound quality (rated 3.8/5); the Teufel Boomster 4 ranks #44 (rated 3.4/5).
Why pick the JBL Boombox 3: IP67 rated. 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.
What the Teufel Boomster 4 does well: Warmer and more open than the Boomster 2021 it replaces, with nicer, less harsh highs, a wide stereo image from its three-way layout (two 20mm tweeters, two 65mm midrange drivers and a 110mm woofer with passive radiators) and good detail. The catch: Side by side with the 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.

Teufel Boomster 4: €249.99 Teufel eBay
Older models: the Teufel Boomster 2021 (ranked lower, rated 3.4/5) and the Teufel Boomster NG (2017) (ranked lower, rated 3.2/5).
Pros: Warmer and more open than the Boomster 2021 it replaces, with nicer, less harsh highs, a wide stereo image from its three-way layout (two 20mm tweeters, two 65mm midrange drivers and a 110mm woofer with passive radiators) and good detail. Its new treble control and remote let you tame the top end. DAB+ and FM radio, a claimed 23 hours of battery at medium volume, IPX5, Bluetooth 5.0 with AAC and aptX HD, multipoint, an aux input, USB-C charging and stereo pairing.
Cons: Side by side with the Boomster 2021 the sound barely changed, and it has a little less deep bass. Against the Harman Kardon Go + Play 3 it sounds sharper and thinner, with weaker bass and a less natural stereo image, and its bass drops off at full volume. At 3.75 kg it is heavy for its size, it has no power bank output, and IPX5 is a step down from the older model’s IPX7.
