Hey guys, looking to get some back up earphones for my Westones. Have my eyes set on some used (gross i know, not a big deal to me after cleaning though) apple in ears. The problem is, MOST of them on ebay are more than 50% cheaper than the apple store. which brings up a valid point about counterfeit. http://cgi.ebay.com/Apple-In-Ear-He...Accessories&hash=item1c160c3ddf#ht_2203wt_907 thats the one im interested in. the seller also has 10K+ feedback. i would ask him, but i was worried he would give me a fake answer. what do you guys think?
