Hello!
Just wanted to know if any of you know of deals the the Shure e2c and e3c earphones? I've seen the e2c on eBay for roughly $50-$60uds+shipping at best.

Questions thought....
what's the big difference between the e2c and e3c?
and also, I noticed on the shure website, they have e2c and e2, as well as e3c and e3. Is there a difference between them?
thanks
