This is how i hear the soundstage right now with my 650s. I'll listen more and maybe make some adjustments or other drawings XD
 
It's a bass sammich

I feel something a little like this, but with crossfeed. else I have only few songs that feel like the sound is forward.

Confirmed that I have the holographic sticker as well! That's a sign of relief haha

 

[chuckwheat]

May or may not be a good thing... but sir you have way too much free time on your hands. Jks

ok maybe there's not that much bass. Maybe only one slice of bass XD.

I finally got my HD650's and I love everything about them, had about a 3 hour listening session with my X7 set on high gain with Direct Mode on. Smooth sound, good stage, nice bass extension and great clarity. Also, I love that the treble is non fatiguing. 

Now the issue, first its almost impossible to adjust the headband, so much effort in order to adjust it and when you pull or push you end up clicking more then just one and it becomes too big or too small. Last, I HATE THE CLAMPING FORCE!!! I have been trying for over an out to bend those metal bands a little to release some pressure but it is not working, tons of pressure on my jaw.

WTB a headphone with this exact sound signature with more comfort!!

You need to bend the fully extended metal parts a lot, but only the metal. You will see then that's the distance between the left and right earcup is larger when not on your head. But again be a little carefull. This can is built to last, that's why the clamp is so forcefull to begin with.

Also be careful not to flex the plastic part of the headband. (Where Sennheiser is written across the top) The paint can come flaking off if you stretch that part.

Can someone please make a video?

I found that even after I bend the headbands on the 600/650, it would still hurt my jaw after half an hour or so. One problem with them comfort wise is that I find there isn't enough vertical and horizontol swivel on the Senn cups, so it's quite hard to divert the clamp away from my (what is apparently odd shaped) jawline. I wish I could turn the earcups a little more to the rear, but the horizontal swivel is only about 10-15 degrees with these and that's not enough for my jaw. The cups also don't have enough downwards swivel which puts additional pressure to the bottom of the jaw. I know Sennheiser probably designed it this way so that it seals tightly, but it really allows for very little room for cup movement which can be uncomfortable for some (like myself). But the biggest reason for my discomfort with these was that the oval cups of these headphones just lined up poorly to the most sensitive parts of my jawline, which is why most headphones with oval shaped earcups hurt my jaw (headphones like CAL!'s, Sony 7506, Bose AE etc are exceptions as their cups are much smaller and have very little clamp)... the big circular ones like the AKG's etc don't and I find them much more comfortable, even though the clamping pressure itself isn't actually all that less. 
 
It's real unfortunate since I probably would have stopped my journey in this hobby with the HD650 since I do REALLY like their sound that much. Instead, I currently have to live with the MA900 as its somewhat similar but technically inferior alternative (that's not a slight on MA900, I do love them for what they are also, but technically they fall short of the Senns IMO). One day I may look into getting these and do some heavy modding to get these as comfortable as I can...

May I ask since when you own them? I remember that my jaw was also irritated first, but the cushions gave in after some time and it simply disappeared.

I'm in the same boat. What fixed it for me was using the HD700 headpad and extending the arms to nearly full extension. With the added height from the hd700 pad, it reduces clamping enough to stop the pressure point on my jaw.

To bring the point home, I had to deal with this issue with my hd580 a couple years ago. Without reducing the clamp, it would put pressure on my thyroid glands just under my jaw and would prevent sessions longer than 20 minutes. Swelling caused from longer sessions would end up with my right ear getting infected and my jaw clicking when I talked.

It was amazing how extending the cups fully quickly changed the comfort. Additionally, I found the HD580/6x0 series sounds a good deal better with the ears positioned nearer the top of the cups. Same goes for my hd800...

I also had some pain around the jaw at first, it went away for good as soon as I found the right length for the armbands. (I ended up with in between 2steps on the side that was hurting, the "clicked" position shorter and the bottom of my ear starts to hurt from touching the pad too much, the "clicked" position longer and I start getting jaw pain after one hour or more. with passing years, my ears start to look like I should learn how to fly, so I have little maneuverability to keep them inside the pads. that's the price of getting old and having those stupid stuff growing until we die.
 
obviously bending the metal pieces helped too as I hate clamping(but be aware that most likely without the clamping as strong, the audio specs will go down, having the right seal with our head is a major part of getting the best sound. me I just don't care at all, comfy stuff > all!!!!
also new pads obviously take little time to get really comfy.

by doing that you put pressure on the plastic, not sure it's the best choice.

Pulling the earcups, it's the same pressure applied by a (slightly bigger) head. It goes way more on the metal than the plastic.
Perspective of the photo can be misleading indeed, the headphone it's sloped. 
Just accelerating what will happen after some week of usage.
 
My two cents.

May I ask since when you own them? I remember that my jaw was also irritated first, but the cushions gave in after some time and it simply disappeared.

The HD650 is the only headphone that I owned the total of THREE separate times... Which shows you I guess how highly I think of the HD650's sound... But twice I sold them due to comfort issues... I lived with my first one for about a year and a half before selling it off, then not long after bought it again to try different things with the headband, but that one lasted maybe about 4 months before I gave up on it. The third time, I only had it for about two months before selling it off to fund the LCD-2's (which, funny enough, ended up being more comfy than the Senns despite their heaviness and HARDER clamp... which made me realize it's just because of how the cups and the frame are shaped)

That's actually an interesting method that I haven't thought of before! Naturally the pressure and the tension on the metal arms will be less when fully extended and that may also change the angle at which the cups puts the pressure... Perhaps I'll try that next time I get to hear the HD650's, perhaps simulating it first by stuffing a lot of padding under the headband and extending it to max...

Would you mind posting a picture of your HD650 with the 700 headband on it?

 

[mikoss]

I found the clamp harsh when new... about 200 hours of listening and the clamp is gone, just feels nice and comfortable. Didn't bother trying to bend anything myself... just putting it out there, if you're patient they will be much more comfortable.

 

[pietcux]

You mean with the HD700 headband cushion?
