Resistance between the tip and the shoulder contacts (the two furthest apart terminals on the plug) With volume slider on maximum : 18.3 ohms With volume slider on minimum : 288.7 ohms I couldn't find any details online. Anyone have a reading from a known good or known fake pair?

>> I'm sure you already have the impedance for the real CX500s to compare to, I was just going to measure the DC resistance as it's simple to do and for A/B comparison, and should be good enough I reckon. Do you know the what the DC resistance is across the plug terminals with volume as min...

I just got some titanum CX500's from Amazon marketplace. I'm trying to work out if they are fake. The strangest thing is that the supplied earbuds, the ones that are actually mounted already, are rounded - same as in this product pic . BUT the other ear supplied ear pieces are double-sealing...
