Rosmadi called it a dust cover. Were talking about the same thing.

Hello,
Excuse me for the translation ... I'm French
I mainly listen to electronic music and Ambient music.
Also, I use my headphones "HD598" for video games (mixamp).
I also use it for TV and film.
It is connected to a Marantz SR6005 amplifier connected to a 7.1 soundcard hdav1.3deluxe.
I try a lot of headphones.
I wear glasses. I can not stand contact lenses.
This is the only one who does not tight my temples.
I had the 595 before (no problem also)
If I did not wear glasses, I would buy without hesitation, the Denon AH-D7000.
I like the sound reproduction de Sennheiser.
The 598 is even better with slightly more pronounced bass.
I can not afford to try the HD 650 and HD700: (
I have renounced the HD650 because it is deemed to have a significant tightening (more than 598).
The plastic of my two headsets emit noise in the ear when I move the head or jaw.
It's pretty rude ... The HD700 has a better finish apparently.
This is why I turn to the HD700 ... Is this the right choice (the best alternative)?
I did find it hot in the beginning. Maybe its break in or me but the treble on the HD700 seemed to smooth out over time. They seem to be getting better and better or I'm adjusting to them. I still alternate between the HD700 and HE400 which are a lot darker and the differences do not bother me at all. Appreciate them both.
They're probably the most comfortable headphones I have ever tried.. even more comfy than the HD800 for me. They seem to fit better.
Congrats.. I'm glad I made the switch from the HD650 to the HD700 though a lot of others may disagree.
The top end does smooth out over time.
I picked up an Audioquest Dragonfly a few days ago and am pretty pleased with the results. My Lyr has been lonely but I'm taking the time to break in the DF.

Love the Lyr. Has the power and dynamics plus the ability to roll tubes. I think I'm pretty much done with looking at amps for now. I may have gone Valhalla but the LCD2 is pretty much my end game (fell in love with them at the last meet I went to). The HD700 was a surprise sidestep for me as I could easily audition and get my hands on it. Haven't heard the Asgard.
Why on earth is wearing glasses effecting this purchase? The D7000 are easily the most comfortable headphones I've ever worn and I wear glasses/loathe contacts, too.
As for the HD700...IMO you might find the clamp too tight as a glasses wearer. The HD800 has a much lower clamping force (for comparisons rather than a recommendation).

Hello,
It has been 5 years since I wear Sennheiser between 5 to 10 hours a day.
I like the pads really thick and soft with an optimum clamping as the HD598.
Clamping force :
HD595≤HD598<HD800<HD600≤HD650<HD700 ???
Beyerdynamic : I have not tried long enough. But, I complain that my ears touching the bottom headsets.
After 10 hours of viewing with glasses, I still have doubts about the comfort D7000.
Unfortunately, I have no means of comparison near me...
Clamping force for me is HD 600 > HD 595 ≥ HD 700 > HD 800
HD 600 has the highest amount, 595 and 700 are quite close to each other and HD 800 has the least amount of clamp. HD 800 will slide off of my head if I tilt it too far back finishing my beer. 
I would have answered sooner, but I just got my HD 700s back from Peter at Double Helix Cables as he was using mine to prototype a cable for it.
I had to show it off. 
Small correction. 700 are looser clamping than 595s, they will start to slide off my head also, but not as easily as 800s. 595s do not.
Sweet! Is it pure copper or copper/sliver.. don't think the HD700 needs a cable with any silver. Let us know what you think.
Yes let us know what you impressions of the cables are. I have an Essence One arriving tomorrow cant wait to see what this combo sounds like.
