Purchased around January 2023. The charging case was replaced at the beginning of May last year. I am selling it because I don't use it much. There are no noticeable scratches or stains, but the battery life of the right earphone is not very good, and there is a charging announcement after about 30 minutes. Please be aware that repairs may be required separately. The box is dirty. There are no major scratches on the main unit, but there is a feeling of use with fine scratches. No claims, no returns. Includes outer box, ear tips, USB-C cable, and instruction manual. Series: LinkBuds Series Model: LinkBuds S WF-LS900N Other features: Noise canceling
