Sound quality is top notch, after testing loads of other headphones between 100 to 1000 euro price range these stand out from the rest to me. No real weaknesses, the sound is little bit warm and dark, but not overly so. The slightly elevated mid bass gives the sound more body, while the dark treble makes sure they never get fatiguing to listen to, never harsh. While the treble is tuned down, its still very detailed. You'll just notice in a busy mix treble tends to take back seat as mids and mid bass rule the show. Sub bass doesn't really exist on these, but its the case with open headphones in general. Overall, its a balanced and natural sound that's very nice and easy to listen to. The detail is there, but it isn't overwhelming or 'fake' like with many Beyerdynamics that emphasize treble too much. Vocals sound exceedingly good on these.
Wearing comfort is otherwise great, but they may have bit too much clamping force. They're very light and if looks are important to you, you won't need to feel embarrassed wearing these on video calls or web conferences, unlike many other audiophile headphones that can look awkward.
As for build quality, its excellent as well. While mostly plastic, this makes it very light. And this plastic is very high quality. I used to obsess on getting headphones with mostly metal build for best durability, but I've learned that it comes with a lot of drawbacks, mainly the weight. Not to mention a lot of headphones that are mostly metal build still have some plastic weakspots that break down over time due to bad design. These seem like they are built to last and will outlast most other headphones in terms of wear and tear. They have also removable cable and all the parts are also replaceable.
All in all recommend to anyone whose looking for a well balanced headphone. Surely, sound won't get much better from here no matter how much more money you spend. These are end game material for even the most demanding users.
