Hehe, that might take a little time. I've got three iems, three cans, and an amp to review before I even get to the Exercise Freaks. I'll try to take the pics soon though, so that I can at least get an audition in for ya (or maybe borrow my friend's unit).
LOL, I would think that anything unexpected at the bottom of a squat is going to be unpleasant.
If you're talking about sibilance, FTFY.
I say go for it. If you don't like 'em, you can always return 'em.
As far as the dying thing goes, are these dying on people within the warranty period? Because then it's just a easy replacement right?
I didn't see anything on Denon's site about a warranty. Also, on earphonessolutions.com, where I found the deal, it said in their return policy that returns were not accepted for Denon (and some other brands). Seems like a storm waiting to happen
