Tested and fully working. The headphones are in good used condition, but the case is a little marked, please refer to photos. The cable with the in-line remote is compatible with Apple devices. Not trying to be funny but they will suit someone with a big head as the headband has expanded out a bit (due to my big head). [eBay code: TP 21 ET]
