It happens with all noise-isolating headphones, because they are so tightly in your ear. It happens with my Shure e2c's. This is no indication of whether your headphones are real or fake.

Dude, we all know they're fakes. What we want to know is how they compare acoustically. Since you own both, what do you think? Hook them up to a radio for a day or two for burning and then let us know how they compare.

I've got a pair of ep630's and wouldn't mind having a backup fake if they were similar. Before I bought them I checked out some of the threads at headfi debating the whole are-ep630's-the-same-as-senn-600's thing. A guy who bought a pair of each said the creatives were good at some audio qualities but lacked in others that the senns were good for. Then another dude who also got both pairs pretty much said exactly the opposite - it was almost like one of them got mislabeled merchandise.

This made it seem to me that the way your phones sound depends upon the batch that they come from - each batch has slightly different qualities. Most of these OEM's have the J-cord, which come on the Senn's. I'm don't know what the reason is - maybe they're cheaper or the chinese who produce them think they're more stylish or whatever. But maybe they just sell better when they're called ep630's because these are cheaper than Senns so Americans on fleabay are more likely to believe they're not random generic crap.

Since you have both, how do they compare? They don't have to be exactly the same, but are the fakes of close audio quality?

Thanks bud.
