Purchased in 2022. One side stopped producing sound, but I continued to use them for a while. I'm selling them now that I've bought a new pair. Since I can't guarantee they work, please consider them as junk. I will ship them in the box of the new earphones via Yu-Packet Mini. The J51 wireless earbuds have a design perfect for sports and everyday use, and come with a charging case and USB cable. - Model Name: J51 True Wireless Earbuds - Included: Charging case, USB cable - Color: White - Left/Right Identification: L, R markings Thank you for looking.
