Series: QuietComfort Model: QuietComfort Earbuds II Connection type: Wireless Other: Junk Basically, it works without problems, but sometimes during use, there are issues like distorted sound or a shift in the left/right audio balance. Therefore, I'm selling it as junk. The charging case contacts are slightly warped. I just charged it, and it seems to be working fine. Accessories are as shown in the photos. The M-size ear tips are torn, so I'm using the S-size ones. Due to the item being sold as junk, no returns or refunds are accepted. ★Please ask any questions in the comments section★
