Operation confirmed. Sound output is normal. It still sounds great. The cable is the original cable (RK-EX1000) modified with a 4.4mm plug from Effect Audio. The condition shows signs of use, scratches, and paint peeling. The earphone filter on the L side is somehow still present, but the R side is missing due to aging. This listing is for the earphones (+ cable) only. Please note that items listed by me may include used items, so I cannot answer inquiries regarding usage period or frequency. Shipping included, this is a bargain price, so please refrain from price negotiations. Immediate purchase is welcome!
