This listing is for the earphones only. I was using them until recently, so they still work well. The battery on the right side drains faster, but I didn't really mind because I was using them with the case. They charge to over 50% with just a few minutes of charging. Reason for no case: I originally bought these used for about 10,000 yen as a secondary pair and loved them, but I dropped the case on the street. I realized it and went back to look for it, but when I found it, it was in pieces (see photo 6). The earphones themselves have no noise and sound normal. I think the battery will be dead by the time I ship them, so please charge them using your XM4 case before using them. The ear tips are size L. Price negotiations are welcome. #Sony #Bluetooth
