I bought the Ec2's from a retailer. I did have a problem with the first set. I returned them directly to Shure and got a new pair within a week.
I have used Shure mics before and their customer service it truly outstanding. They have patiently supported stuff that is 12 years old. In one case they no longer made a part and referred me to a retired Shure employee who did a cottage business fabricating such things.
Great people.
One question:

What is the burn period for these things? I did try the 5's on a no questions asked return offer directly from Shure. They did not seem so much better than the 2's for the realtively few hours I used them. I put that down to my ears and/or the noisy ambience air travel - but do these thing improve with use?
