The M50's are an amazing headphone for the price. Probably the best you can get. I just picked up a pair on Amazon for $130. I was expecting amazing headphones from the reviews on them, and they delivered. They were even better than I expected. I haven't played through the cab clones on the marks but I have played plenty using bias on the computer. Most popular headphones, like Dre's beats, are very bass heavy. And by very bass heavy I mean there is so much bass its a problem. The M50's are EQ'd pretty flat, so they're perfect guitar. Plus, when you're not playing, you can enjoy listening to your favorite music through the M50's. I can't say enough about these headphones. From playing guitar through them to listening to music, these things are worth their weight in gold. Best $130 I've ever spent. If $130 is too much for you I would recommend you get something with a flat EQ. Or studio monitor headphones. Audio Technica makes some cheaper designs as well. Stay away from the stuff the kids are buying. You want something that's going to give you a true sound. But if you can, get the M50x's.
