I am the original owner, having purchased this item new. I used it for about three years, but not very often, and then stored it for a while. I have never used the original ear tips, so they are in home storage, but I will include unused ones in all sizes. It works without any problems, but please be aware that the battery and other components may have deteriorated due to age. This item can also be used for parts, such as for charging components or for those who have lost one side. I have the original box and all its contents. I will include it for an additional 800 yen, including shipping and handling. Please inquire in the question section. High-quality wireless earphones, made by Sennheiser. - Brand: Sennheiser - Color: White - Case Material: Fabric - Country of Manufacture: Germany Thank you for looking.
