Thanks for the heads up. When I demo a potential product, I try it out extensively until the salesman kicks me out of the store.
The most memorable moment was @ Tweeter, I was almost escorted out by the manager cause I was breaking in the Sennheiser MX500 earbuds for about two hours (brought my own CDs). I then bought them (for my father, I don't like ear buds) after I was satisfied.
gloco - in my cases, it's opposite. When they actually hear it, it causes commodity like "these sound so awesome, why the hell didn't you tell me about crazy headFONES earlier?"
"hello! That's what I've been trying to get through to you all this time" lol. But eventually they shut up, then hog my headphone rig. It's ok, I just blast the speakers. =P
