High-quality wireless earbuds with a comfortable fit. - Brand: SONY - Model Name: LinkBuds S - Included: USB-C cable Thank you for viewing. The right earbud's battery dies in about 30 minutes. Also, the main unit blinks orange when charging, and an issue occurs before it's fully charged. Charging the case itself seems to be fine. I used them in the case, so the condition is quite good, but I will sell them as junk items due to the above reasons.
