Wireless over-ear headphones with noise-canceling function. - Color: Black - Design: Over-ear - Function: Wireless - Features: Noise-canceling function - Connection type: Bluetooth Thank you for viewing. This product only works with a wired connection. Bluetooth does not function. I don't know how to fix it, so I'm selling it as junk. Recommended for those with a warranty, those who only want to use it wired, or for fashion purposes. Wired earphone jack included.
