Up for sale is my IE300. 100% authentic and working great, no channel imbalance or problems of any kind. The pouch went missing and I pulled out some memory wire out of the original single ended cable. Cable still works fine so not a big deal. I’m not sure if they are the original tips. Price includes express shipping (10 working days to USA and UK). Other countries please contact me for a postage price, I’ll see if I can ship them to you for free.
