I have never used this item after purchasing it new. This is a set of accessories for the wired earphones KBear Ink MK2, including the cable, ear tips, cleaning tool, and cloth. The cable has a flat 2-pin connector and a 3.5mm plug. The ear tips come in sizes S, M, and L, with one pair of each size, for a total of 3 pairs. I plan to ship via Yu-Packet Post Mini. No one in the household smokes. We do not have any pets. I don't have many items listed, but I welcome combined purchases. If items can be shipped together, I will discount the shipping cost.
