Thank you for viewing. This is a listing for the MDR-NC31 earphones for SONY Walkman. There are no noticeable stains or scratches. Used infrequently. The ear tips have been replaced with new, unused ones. I confirmed with a Walkman, and it produced a very good sound with strong bass. Operation has been confirmed. Compatible with 3.5mm 5-pole mini-plug Walkmans and also with Xperia smartphones that have noise-canceling functionality. Currently, I am carefully storing it until a purchase is made. Thank you for your consideration.
