SONY LinkBuds S WF-LS900N White - Right Ear Only Used for about a year. Still usable, but selling because I lost the left earbud. Please see the images for the detailed condition. Be sure to initialize the earbud with your existing one before use. I don't think there are any noticeable stains, but it has been stored at home, so please refrain from purchasing if you are concerned. Returns and refunds are not accepted after purchase.
