LinkBuds UC, optimized for Microsoft Teams, offers a comfortable fit and high-quality sound. - Model Name: LinkBuds UC - Application: For Microsoft Teams - Color: Black - Accessories: Charging case, USB adapter Thank you for viewing. The product was replaced with a new one after being sent to the manufacturer for repair. The main unit and ear tips are new. (The manufacturer confirmed the operation, so there might be some fingerprints. Please understand.) All sizes of ear tips are included. The box is used and has some tears as shown in the photos. Also, since the USB charging cable is missing, I will include a suitable cable. Thank you for your consideration.
