Not really that I'm aware of. There is, but it requires some modification. What I did was take the Beyer Dynamic DT-235 and replace the pads with those of the Maxell DHP-II ($30-$40). You now have converted the DT-235 to a circumaural headphone and it's probably the most comfortable headphone ever made. There is ZERO clamping force and the pads feel just like the Triports.
I was just going to say get the DHP-II but those are semi-open. They might have enough isolation to make them sound closed. On the sides there is a small grill with foam behind it. If it wasn't for that they'd be closed. Those have memory foam for the pads.
I use both these headphones and it's hard to say which sounds the best.
Actually one idea is the AKG K44 MK II. I don't know if it sounds better than the Triport but they're dirt cheap. Zero clamping force with them, but they are a little goofy looking.
MDR-V6 with the Pearstone Velour pads is also one option, but they will make your ears hot after a few hours.
Koss Pro DJ 100 with the M30/V6 pads is also extremely comfortable. You'd have to pay $80 for the headphone and $15 for the pads.
BTW I think for classical, the DT-235 is pretty nice. The pads out of the box are that fuzzy velour, but they're supra-aural. They're very comfortable though. Somehow the DHP-II pads fits them PERFECTLY. Who would have known!
Here's a picture of the DT-235 with the DHP-II pads. The pads are basically the same as the Triport pads. Memory foam and all. Tell me if these are not the ugliest, most comfortable headphones ever! I think if I was sent the black version I had ordered, they'd look pretty cool! You just wouldn't believe how comfortable these are on your head!
