Sennheiser HD 25-1 II by tablo
I bought these for $129.95 from Amazon.com. I owned Shure SRH750DJs before this, but found them very uncomfortable due to high clamping force and the headband which becomes flat upon wearing.
Sound quality is excellent. The sound is well-balanced with a slight reduction in midrange emphasis, have good clarity and detail, and are quite transparent when it comes to sources. The bass is tight and accurate. These are very comfortable, since they are very light. They almost feel like toys. Not only these headphones are good for studio use, they're the perfect portable headphones too. You see a LOT of DJs and cameraman/audio staff using these headphones.
Pros: Tight bass
Comfortable, very light
Cable is not ridiculously long
Cons: Uncomfortable when using the headphones with glasses on; the problem can be fixed by having your glasses' legs sit a bit above your ears.
A bit pricey at normal price
