Verdict

The Loewe Klang S3 is a premium smart radio and streaming speaker featuring a 120-watt total music power output (2 x 30W RMS) housed in a brushed aluminum casing measuring 460 x 160 x 90 mm and weighing 4.8 kg. Its primary characteristics include an integrated slot-loading CD player, FM/DAB/DAB+ tuners, Internet radio capable of programming up to 25,000 stations, and a large 3.2-inch full-color display. The main advantages are its diverse audio sourcing options—including native Wi-Fi streaming for Spotify Connect, Amazon Music, and Deezer—as well as individual bass and treble controls that deliver punchy stereo sound with a modern, award-winning design. On the downside, despite marketing elements labeling it as a portable system, it requires constant power from an AC wall outlet since it has no built-in battery, relies on older Bluetooth 4.2 technology, lacks a standard 3.5mm AUX input, and features an awkwardly positioned rear USB port.
