Thank you for viewing. I have used this for about 3 months. There are no issues with the operation, but I have lost the medium-sized silicone ear tips for the earphones. Regarding the silicone ear tips, please note that I will only send the unused ones (small x 2, large x 2). Everything in the first photo is what will be sent. (Main unit, box, charging USB, 2 types of silicone ear tips) Thank you for your consideration.
