$7 off the KZ ES3, may be as low as $5 [ships from China]

For a limited time, coupon code NBVJQAYF drops $7 off the KZ ES3 earphones at ships-from-China seller GeekBuying. You need an account to test the coupon. The current price on their website is $11.59. I don’t know if the coupon is stackable with the discount, thus making it $4.59 or not. I don’t have an account with them, so unfortunately I can’t test the coupon.
