Zipper-headphones

Zipper

— reversible wire (see "Cable entry"), in which the individual wires are hidden inside the halves of the zipper. The fastener does not cover the entire length of the cable, but usually takes up half, or even more. The headphones themselves with a similar wire most often belong to miniature varieties — in-ear or in-ear. Such models are very convenient in “packing” and “unpacking” for storage and carrying: by zipping up, you can connect two wires into one, and when you need the headphones again, you can unzip them by separating them. At the same time, the fastened zipper is very resistant to tangling. Yes, and this accessory looks quite unusual.
