With the Aventho 300, Beyerdynamic is clearly focussing on good sound - and it delivers. The over-ear headphones are fun with all genres, sound round and balanced and score with excellent spatiality. They are also practical when you're on the move: their rechargeable battery lasts for longer journeys and their noise cancelling is definitely suitable for everyday use, even if it's not impressive...

With 50 hours of playtime, this is an extremely durable all-rounder with good performance in terms of sound, noise cancelling and features - but the equaliser and wearing comfort are only average.

The Aventho 300 has the potential to be right up there with the best. It offers first-class battery life, sits comfortably on the head and is easy to control. The effective ANC is also part of the good foundation. There are only minor complaints about the sound, such as the slightly muddy reproduction. Not enough for a top spot.

The Aventho 300 has the potential to be at the forefront. It has a record-breaking length and sits comfortably on the head. There is little to criticise in terms of sound. Overall, this is enough for a "good" headphone, but not an outstanding one. Alternative: the Sonos Ace for the same money with a test score of 1.2.

I like technology, but not only in its latest form, but also in classic analogue form: I still take photos on film, listen to music on vinyl and watch linear TV. In all cases, however, in parallel to the digital stream. Only my highly valued hi-fi headphones are still from yesterday and have a metre-long fabric cable to the system...

In our test, the Aventho 300 left us with mixed impressions. The workmanship, operation and functions are first-class. In terms of sound, it was well positioned, but lacked that last bit of fine dynamics, airiness and detail. The EQ does help a little, but you can expect more for the price.
