Teufel Boomster 4: €249.99 Teufel eBay
Older models: the Teufel Boomster 2021 (rated 3.4/5) and the Teufel Boomster NG (2017) (rated 3.2/5).
Pros: A stereo boombox with DAB+ and FM radio on a telescoping antenna, driven by 42W RMS into two 20mm tweeters, two 65mm midrange drivers and a 110mm woofer with passive bass radiators. Teufel claims up to 23 hours of battery life at medium volume, 5 hours more than the 2021 model, plus IPX5 water resistance, Bluetooth 5.0 with AAC and aptX HD, multipoint pairing, an aux input, USB-C charging and an included remote. Two units pair for stereo.
Cons: No independent measurements yet, so its sound and output can’t be compared with ranked speakers. At 3.75 kg it is heavy for its size, and it has no power bank output for charging a phone.
