This is the neckband-style SONY noise-canceling wireless earphones, the WI-1000X. I used to use these and have kept them in the box since I replaced them. Both the noise cancellation and sound quality are excellent. There is some wear and tear. They were working normally before storage, but since they are used items, please understand that they are non-refundable and non-returnable. - Brand: SONY - Model Name: WI-1000X Thank you for looking.
