Most Comfortable Headphones?

Supposedly these are extremely comfortable headphones:

You'll never get anyone to agree on a question like this, but Denons are extraordinarily comfortable as are the beyers. I have scarcely heard a word against them in terms of comfort.

To be honest, I think you would be better off trying to avoid uncomfortable pairs of phones rather than finding the most comfortable. To that end, avoid grados and the K701.

Beyerdynamic DT880's are pretty much my favorite headphones in terms of comfort and sound quality.

I've had all day listening sessions and never felt the need to take them off due to discomfort or heat issues, unlike my RS-2's, which sound great, but require comfort breaks every once in a while.

The DT250s are the comfiest I've had, AD900s aren't as comfy (as I have a small head). Both are super comfy for long session - whole day, though I can see your ears might get hot in DT250s if the weather is hot and you don't have aircon.

Beyer DT770/880/990 with the soft textured velour covers and soft foam padding that molds to your skin. Add in the sturdy metal frame and they're built like a tank, er, like if Rolls Royce built a tank. That you wore on your head

K-701/2.

Sennheiser HD555/595 are so comfortable that they almost disappear.

That was classic.

Oh and btw it was a record for me today, i saw 7 Rolls Royces today, 5 Phantoms and 2 old ones.. went to look at houses in Beverly Hills today so..

Even with the headband bumps?

I've put on the K701 for hours and didn't even feel the bumps. I think those who complained about the discomfort of K701 have either a huge, squarey or long head that causes the elastic self-adjusting headband to put too much pressure on the top of the scalp. Plus, having a nice, thick layer of hair helps "dampening" the discomfort. lol

Other than that, I would say my MS1000 is by far the lightest and most comfortable headphone I've tried. So light, that I sometimes forgot I had them on. I tried the GS1000 too, but the leather headband weighs more than the wooden drivers combined; one reason why I love the pleather headband of lower end Grados.

Yep, for after hours the GMPs are very comfortable 220g.

The Audiotechnica AD700s have been described page up and page down as being extremely comfortable "a can I'd wear all day", and I bought them as a work set for this exact reason.

They are lower budget though (about $100 @ eBay), but are described as having sound qualities above their price class (I wouldn't know, haven't received them yet).

Ya, the AD700s are terrifically comfortable for my large head. For some reason though, my wife keeps laughing at me every time she sees them on me.
