I suspect I've got an HD650 with HD600 drivers inside. I suspect this because i bought my HD650 used, and the sound is not as I've seen it described I've seen it described as being much warmer/laid back/more bassy than the Beyerdynamic DT880, and the in the model I've got here that's not the case.
But anyway, regardless of my suspicions, how easy would it be to take out the driver of the HD650 and swap it with the HD600 driver? They're identical in size, and shape and connections, aren't they?
If it is easy to swap them, it would be a cheap upgrade if you've already got an HD600, to buy an HD650, put the drivers of the HD650 in your HD600 and the drivers of your HD600 in the new HD650, then return the HD650 (within the returnable period) and get your money back. You've just upgraded your headphone from a HD600 to a HD650, without paying a dime!! And now there is a HD650 with HD600 drivers on the market (which I suspect I've bought).
I'm not saying people do this, nor am I advising you to, obviously, but if it is easy to swap the drivers round, I may have gotten conned...?
