First, we are very sorry for the long delay of the shipment of new YUIN earphones. We've been informed by YUIN China that they can't supply new YUIN series of earphones before the end of 2008 Beijing Olympics for unannounced reasons. Hence we have to stop taking orders for PK2/PK3 earphones. Currently only a few YUIN PK1 earphones are available. Thanks for your understanding.

[11 July 2008 Updated] Finally, we sorted out the problem of supply. New YUIN PK1/PK2/PK3 and OK series of in-ear earphones are on their way.
