Thank you for viewing! This is a listing for the MDR-NC033 noise-canceling earphones for Walkman. I purchased these new earphones to use with a Walkman, but I decided not to buy a Walkman, so they are no longer needed and I am listing them. I opened the package once for taking photos, but they are unused. Spare ear tips are included. A cap to close the Walkman's charging port is also included. They can be used with Walkmans that support a 3.5mm 5-pole mini-plug, and also with smartphones like Xperia that have a noise-canceling function. I am currently storing them carefully until a buyer is found. Thank you for your consideration.
