I didn't expect them to be so comfortable, they don't tire at all after many hours on the PC. I think the premiums are more than usual. I had more expensive ones from the same company as well as others... they all suffer from reliability over time, whether it's the speaker, the arm, the cable, etc. So, the very expensive ones for me, YES, are the most important for the sound... but when the headphone screw breaks... well, then only the sound doesn't matter. IMPORTANT: the cable output is a 6.35mm plug (permanent)

Prefer another model. This specific one has a specific flaw: the low mids are boosted and managed throughout the entire midrange spectrum.

This practically means that everything sounds as if there is a curtain between the ear and the sound: the bass is muddy and indistinct - I would prefer if it didn't exist at all.

Otherwise, they are very good in terms of quality, sound isolation, comfort, and resolution with a nice stage. But what can you do... Personally, I corrected the bass (completely attenuated them with a soft EQ) to clean up the sound, but ultimately I realized that this is not a solution (you can't have EQ everywhere) and I returned them. If you dare, at least prefer the 569 which seems to have a different driver and better quality. Of course, with so much money, you start to think if it's worth bringing in an HD 58X from outside... which will cost around 200 but will cover you from all sides without experiments.

For their price, they are wonderful. They have an open stage sound with good mids and highs. Obviously, there is no bass since they are open back headphones.

Very good quality-price ratio. Sound insulation doesn't make sense since they are open headphones. The package does not include a cable or a mini-jack adapter...
