Hello I'm selling my Yuin OK1s. I'm asking $150 shipped and paypalled, firm. Buyer will receive the earphones and various buds and tips, as seen in the picture. I do not have the original box or the 3.5->6.35" adaptor. These are however the best earbuds I have ever heard. I have feedback on both audiogon and ebay under the same username, emak212.
