The market for portable speakers with AirPlay is still small, but is growing steadily. There were no real failures in our test, with the Beosound A5 definitely leading the ranking in terms of sound. It is followed at some distance by the Sonos Move 2, the Teufel Motiv Home and the Bose Portable Smart Speaker, closely followed by the Boombox and Authentics from JBL...

There is something for every taste and budget in the test field. If you want to invest a little more and also want to fill your own four walls with music, the best choice is the test winner from Sonos. Connected to your home Wi-Fi, the compact speaker also functions as a smart Alexa speaker and connects to other Sonos speakers...

Apart from a few minor flaws, the Sonos Roam is a brilliant speaker that combines Wi-Fi, Bluetooth and smart features in a sleek, compact and robust design.

Up to ten hours of battery operation are possible, charging is via a USB-C cable - unfortunately, a power supply unit is not included. A special charging dock for the Roam costs around 50 euros extra. However, the annoyance about such business practices fades after switching on: Hardly any other box of a comparable size is likely to make so much steam (and joy).

Wireless speakers can play music from many sources. Our wireless speaker test shows which speakers sound very good - and why expensive does not automatically mean good. The speakers are controlled via app or voice assistant. In the latest test, Stiftung Warentest tested twelve wireless speakers from Amazon, Audio Pro, Bang & Olufsen, Bose, Denon, Google, Ikea, Philips, Sonos, Sony, Teufel and Xiaomi.

Sonos has priced the Roam well and there are many good things to say about this elegant, compact and clever speaker. It is IP67 certified, can be placed anywhere and can be charged wirelessly. A feature rarely found in a speaker. As you would expect from Sonos, the sound quality is also excellent...
