Audio-Technica Sealed Canal-Type Inner-Ear Headphones ATH-CK251TV Purchased about six months ago at an Edion store. As I had a similar product at home, this item has been stored unused. I am listing it because I do not plan to use it in the future. The following is a quote from the Edion website: ● Equipped with a high-performance driver in a compact body. Reproduces TV audio clearly. ● Features a sealed type that is ideal for when you want to listen to audio quietly. Excellent sound isolation and minimal sound leakage. ● Equipped with a volume controller for adjusting the volume at hand. ● Includes a convenient cord clip to attach to clothing. ● Includes four sizes of ear tips (XS, S, M, L).
