Input:
That's right, I've had these headphones for over 5 years. I bought them at Guitar Center when I was first getting into studio recording. I decided to write a review now because I was curious as to how much they are selling for these days (bought mine new for $100).

The dynamics are amazing, especially the bass response. I share a house with roommates so at times I can't listen back to my recordings through my monitors/subwoofer, but these headphones do a great job as a substitute. The sound is sufficient enough to hear all the little nuances during a recording session. They are VERY COMFORTABLE, too. They hug my ears and are virtually weightless.

I also have a pair of Bose around ear headphones that I received as a gift. I thought for the reputation and price the Bose would be a replacement for my Sony's, but I was surprised to hear that the Bose lacked the bass response that the Sony's had. The Bose are great for listening to CD's, Mp3's, etc. but for my hobby they just didn't compare to the MDR's.

After all this time the only problem I've had is simply cosmetic. The material that wraps the surface of the head band (I think it may be a very thin vinyl) has split, probably my own fault. But that doesn't affect the sound or comfortableness one bit.

I will probably buy another pair just to have as a spare. I am very impressed with this product and if I ever open my own professional recording studio I will most likely outfit it with 3-4 pair of these.
