Yep, just found some fake ATH-CK5's. Wanna know how it's fake? >
Here's a fake.
I've circled all the points that would make this an obvious fake.
Why it is fake:
1. The logo is imprinted on with thick, white lines.
2. The 3.5mm end-plug does not look like that.
3. The L and R letters are imprinted in white.
4. The CK5 logo is missing.
How to tell if it's real:
1. The logo is in very THIN white lines. Although it doesn't rub off easily, it can, but it surely does not look that thick.
2. The 3.5mm plug should look IDENTICAL to the Panasonic HJE50 IEM's.
3. The L and R are NOT imprinted; they're molded with rubber so you can feel the rubber sticking out.
4. The CK5 logo should be on the underside of the L and R; also molded in with rubber, so you can feel it.
HOPE THIS HELPS AGAIN, POTENTIAL BUYERS!
