Is this stuff fake?

Hey guys, I found the so called "official" Monster page on eBay, and a lot of the nice earphones/headphones they're selling are on sale for pretty cheap compared to how much they are in stores. I'm kind of hesitant to buy anything I want because I feel like the stuff could be fake, but idk since it seems to be the official Monster page. can anyone confirm or give me an opinion? Thanks
Here is the page: http://stores.ebay.com/MonsterProducts/_i.html?_sasi=1&_sid=1105930875&_trksid=p4634.m322
If you go under "Headphones", you can see some pretty nice stuff that usually sells for more.
can anyone confirm whether this page is authentic, or give me an opinion? Thanks
