You can buy replica beats at a few places although the quality might not be what you're looking for. Not that those Dre headphones are the best or anything. There are plenty of headphones that are far superior than Beats. With fake Beats, you're just buying for looks, basically with the "b" symbol on the sides.

Doing a quick search, I found several sites, mainly from China BUT buy with CAUTION! As with any site that sells fake stuff, there's always a chance that they're not legit and even if they are, you'll get what you pay for although if you're looking for replicas, then you probably don't care.

The picture of Beats on one of the sites I saw looked real enough, but sound quality won't be obviously. Getting low quality ones isn't a problem, having your credit card number stolen is.

Again, buy at these sites at your own risk! Potentially getting scammed isn't worth saving some money. If anything, go with Ebay. At least you can view the seller's ratings so you can better avoid the scam sellers on there.

Unless you can find 3rd party reviews on the trustworthiness of the site, I suggest you avoid sites you're unfamiliar with.

Better yet, choose a different brand of headphones. There are plenty that are cheaper and better quality than beats.

Just my 2 cents.
