These are the KITH x Bose Ultra Open Earbuds in black, featuring wireless Bluetooth technology and an ear-hook form factor. They were used 2-3 times and since then have been sitting in the original box it came in. These are a great pair of earbuds especially if you like them not being completely inside your ears. Last sale for them was $800 on StockX so these are pretty sought after. If you end up buying these I truly hope you enjoyed them as much as I did :). If you have any questions regarding this particular listing please feel free to message me and I will be glad to answer them. Have a wonderful day!
