The headphones are very good, detailed, lightweight for extended use, and overall a good choice. For music production, which I use them for at this price range, they have impressed me, even though I don't have much experience with headphones because I usually work with speakers. I love them. They perform very well at all frequencies, and as for durability, only time will tell.

The headphones are simply amazing! I went from the 300 Pro to these as soon as they were released, and I couldn't believe that the sound could get even better. Generally, I have been a fan of Sennheiser for many years and exclusively use their headphones.

We are talking about complete clarity of sound, frequencies, and all details (as Sennheiser generally offers) - it's a new world where you can perceive everything. With the 120 Ohm, the frequencies are now more "stable" and no longer "flicker," and with the drivers at a slight angle, the soundstage becomes incredible.

Also, the open-back feeling is fantastic because it helps with the soundstage, it doesn't isolate you completely from surrounding sounds (I personally prefer this), and in the summer, it also keeps your ears cool (very important for Greece). But strangely enough, they have very good sound isolation for open-back headphones...

But the most important thing for me is that you have a personal 2.1 system in your ears - as the company has already mentioned, special emphasis has been placed on low and very low frequencies to reproduce them with great fidelity - the result, for me, is like having a personal subwoofer in your headphones. They are neither harsh nor boomy - there is a sweet... extension in the lows!

Finally, the velvet pads feel great, and their construction is very sturdy - and know that they are also incredibly lightweight, so they don't tire you at all...
