These Etymotic ER4SR are fully functional in excellent condition, its missing most accessories / tips and the price is adjusted to reflect this however, one set of triple flange will be included to get you out of trouble.

(I suggest long-term you source new tips from Etymotic when you're ready)

The sale comes with the earphones, the carry case, one set of tips and the certificate of performance which shows their personal frequency response. If you're willing to buy them and get some tips later you'll have an excellent set of earphones and still save some money.
