Used once (for about 20 minutes). I found the one I was originally using, so I'm putting this up for sale!!!! *Final price reduction.* ⬜︎ Purchased at a JBL authorized store (electronics retailer) for 13,200 yen. I bought these because I lost my earphones, but I found them, so I'd like to sell these! *The package of the instruction manual is partially torn. Please be aware of this beforehand.
