How much are beats headphones and the sound?


How much are a pair of beats headphones? I imagine they are expensive, but are they worth it? Do they have really good sound?

I should have added above that they are fairly well built. I only say that because I know how hard my son is on his portable stuff. He's on his fifth or sixth iPod, but the same pair of Beats.
Dr Dre was the sole owner of beats audio, He contracted the specifications to monster audio to produce his product!, then Dr Dre met Htc cell phone company, made a deal for soft ware, BTW, is better than the headphones by alot!,, to be put on their HTC products, HTC liked the soft ware, they made Dre Dre an offer he could not refuse for controlling capital in his company!, million, up-on millions of dollars did he make off with!, kinda like robing a bank in his case, LOL!, Dr Dre still owns some of the company, and yes, they are still prodused by monster audio for HTC!, and another note, the beats audio soft ware is on some HP lap top computer models, with a whole recording beats audio soft ware for studio use!
BTW, Dr Dre is a rapper and studio engineer and professional DJ world wide!, No, He is not my cup of tea, You got to give it to him, A damn good business man!
