Thank you for viewing. SONY Linkbuds s Purchase date: March 2023 Usage frequency: Twice a week, 2 hours I mainly used them for meetings and online lessons, and since I didn't use them very often, I never felt any problems with the battery. However, there's a slight hissing noise in the right earbud, which bothers me during meetings, so I've decided to replace them. It bothered me during meetings, but it might not be very noticeable when used for scenes with loud sounds, such as online games. If anyone wants to try them out at a low price, please do.
