Ive had a set on the front of my car for about 3 weeks now, about 350 miles of driving on them mostly in town. Ive got this vibration that has been going on since I put these rotors on, so I know its related. It is NOT a shimmy, shake, or wobble like a warped rotor. Its a vibration. Sounds and feels like a wheel bearing, but it only does it when the brakes are applied. The harder I press on the brakes the louder it gets. If I let off the brakes completely, it goes away completely. This is most prominent between 30 and 20 mph when braking, but I can feel and hear it at any speed when I apply the brakes. This also gets worse as the rotors get warmed up.

I'm wondering, is this just a characteristic of these rotors? Or might I have gotten a bum set from EBC?
Ive sent an email to EBC asking them about this, but Im also looking for some input from others who might have used them.

Sounds like an out of round rotor.
