This is an unopened item. This is the KZ merga, a wired, re-cableable earphone featuring one 8mm and one 10mm dynamic driver from KZ. The included cable has a QDC connector and a 3.5mm plug with a microphone. Bundling with other KZ and CVJ products I have listed will result in a 300 yen discount per additional item. Please comment with any questions about the product. Shipping is planned via Yu-packet Post Mini. No one in the household smokes. No pets are kept. Although I don't have many items listed, combined purchases are welcome. If items can be shipped together, I will discount the shipping cost.
