MDR-7506 : Very satisfied

These headphones are simply the best I have ever put on (maybe the first ones in this price range though).

I was surprised when I took them out of the box.

The headphones were lighter than the cable!

I'm not an expert in sound quality, but the sound is quite even throughout the spectrum.

Recommended.

Update, 3 years:

Does not need much power to get a decent room listening volume - On Windows my volume is sitting at 6.

Not a single part has broken with almost daily use - Some of it spent folded inside a backpack without the protective cover.

Extremely durable, Extremely satisfied.

Only drawback is that the plug end of the cable is under a lot of stress when the cable hangs freely because of the weight of the cable.
