The Bose loudspeaker rightly bears the addition "Flex" in its name, because it can be used flexibly: well protected against dust and water, standing, lying down or suspended from the loop. However, the equipment only includes the bare essentials. But the most important thing is that the little one packs a real punch...

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...

You'll be well equipped for your next picnic with the Bose Soundlink Flex. Not only is the Bluetooth speaker waterproof and dustproof, with its effective sound it can make itself heard effectively, especially outdoors. The workmanship and design are high-quality but simple and the operation leaves nothing to be desired except for sound adjustment...

A powerful bass, clearly audible details and a balanced, lively sound - that's what the perfect Bluetooth speaker should sound like. However, good sound quality is not everything: to become a test winner, a speaker should ideally also be easy to use, have a long-lasting battery and offer practical additional functions...

The Bose Soundlink Flex not only looks chic and valuable, it also offers a pleasantly warm sound. However, the bass sometimes wants a bit much. This cannot be changed in the accompanying app, in which Bose explains the controls wonderfully with small animations. With a little distance to walls and outdoors, the sound is great. The low weight and long battery life are also fun.
