if you wait, there are a few that pop out every now and then. I just got introduced to Grados last weekend when I got a pair of SR60s. 3 days later, I got an SR80i and I know it will not stop there. Right now Im trying to figure out if I should try ultrasones because i need a pair during plane rides but im guessing i may regret it. :)
I've never had the opportunity to check out some grados. I'm not even sure why; I just never set it as a priority listen. I keep wandering into all these "show off your mods" threads and am getting a serious itch to buy a pair.
