Summary: These headphones produce an amazing sound. it is quite different from your run-of-the-mill over-ear headphones and certainly different from any ear buds you've ever used. The sort of surround-sound effect that a lot of artists record with these days is amplified by the quality of these headphones. They are also very comfortable.
Summary: Sitting here working the contest with my Icom 756 Pro II and can hardly feel these headphones. Just so comfortable. I got rid of my Kenwood hs-6 and hs-5 for these and don't regret it for a minute.Can't even hear my dog or my xyl bark!
Summary: These phones are a common choice in the $100 and under price bracket, but I don't think they are the best choice. They are pretty reliable, but like most [cheap] headphones, are built kinda cheap. They don't feel very 'solid', though they'll work fine and can take fair amount of abuse and drops. One thing that really annoys me with these phones is that the muffs don't completely seal around your ear to your head, leaving the space open for sound to leak in or out.
Summary: I love my Sony MDR 7506s. My first pair is a hand me down that the previous owner had for years and thought would give out any day. That was almost two years ago. I still use them every session. They sound great. All of my other headphones would break after 1 year of use (right outside the warranty window). I couldn't be happier. They give a very fair representation of the sound in my opinion.
Summary: They have a very honest sound and are nearly colorless. I used Yamaha NS-10's for my near field playback and used these phones to make sure that the mix was correct - comparing these two references. Ah; it was the way I did things at the time. But it worked. Very honest sound that I felt was reliable. The quality of the build materials was first-rate at that time. They can get to feel a bit heavy after a few hours. But not cumbersome nor too heavy by any means.
Summary: These aren't the best cans in the market, but I have seen these in nearly every studio and live rig I've seen. They are reference cans. After a short break in time, the near flat response is consistent over time. While the ear can acclimatize to any headphone, the MDR 7506 provides a pretty neutral space for evaluating any mix.
Summary: one of the reasons why i bought a pair was that i can afford. i had very limited choices back then. it had good reviews so i decided on them. no regrets because they were very useful. although they are far from the very advanced ones in the market, you can still use it for listening to good music. although i buy headphones from time to time, this has always been my back up.
