Technics EAH-AZ100 - Left earbud only. Includes almost unused ear tips (XS, S, ML, L) that were only worn for testing. Also, the M size ear tips that came with the main unit are in near-new condition as I used third-party ones. While listed as "no noticeable scratches or stains," the actual product is in very good condition as shown in the photos. *Please refrain from purchasing if you are overly concerned. *Please check the photos.
