Thank you for viewing. This is an over-ear wireless headset stored in a compact black case. It uses bone conduction, which is less affected by ambient noise, making it easier to hear the other person's voice. At the same time, unlike regular noise-canceling earphones, it doesn't block your ears, so you can hear the sounds you need, which is convenient. - Case color: Black - Accessories: Dedicated charging cable, storage case, USB Bluetooth receiver
