#50 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). See every Teufel Boomster generation.

Pros: A stereo boombox with DAB+ and FM radio, a long battery, splash resistance and a remote with treble control. A 3.75 kg three-way stereo boombox with DAB+ and FM radio, a claimed 23 hours of battery, IPX5 and a remote with treble control. It sounds warmer and more open than the Teufel Boomster 2021 it replaces, with nicer, less harsh highs, good detail and a wide stereo image from two 20mm tweeters, two 65mm midrange drivers and a 110mm woofer with passive radiators. The treble control lets you tame the top end. Bluetooth 5.0 with AAC and aptX HD, multipoint, an aux input, USB-C charging and stereo pairing.

Cons: Side by side with the Teufel 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.
