SONY WF-C500 Junk Received as a prize in July 2024 and used 2-3 times. Since the usage frequency was low, both the earphone body and the charging case are in good condition, I think. - The right (R) earphone does not turn on, so please consider it as junk. - The left (L) earphone works and connects via Bluetooth without any problems. Everything in the photos is included.
