Thank you for viewing this product. This is the Soundcore Liberty 4 NC, wireless earbuds with noise-canceling function. It's a calm navy color. Operation has been confirmed. I used a silicone case, so the charging case doesn't have any noticeable scratches and I think it's in good condition. I used it for about 2 months. There were no particular problems with the noise cancellation or battery life. A silicone case is also included. I will ship it as soon as possible. ■ About the product This product is used.
