These Denon AH-D5200 headphones have been upgraded with Denon AH-D9200 drivers.
I also own a set of 'real' AH-D9200s and got an extra set of drivers which I used to upgrade these headphones.

When I did the driver swap a posted about the difference between the drivers:

I have been keeping these as a backup in case I ever had any problems with my D9200s, as I like them so much, but I have now decided to sell them. These have been used very little, and are in excellent condition, as can be seen from the photos.

Now, about the sound...
These sound almost the same as the D9200s, and much more resolving that the original D5200s.
I would describe these as sounding slightly richer than the D9200s, although the difference isn't big to my ears.
As far as I can tell, the earpads are the same on both, other than the colour. The earcups on these are beautiful, dark zebra wood, whereas they're bamboo on the D9200s.
Another difference worth mentioning is that the headband on these has softer padding than on the D9200s and, as a result, I find these a little more comfortable.

Includes the original cable, carry pouch and packaging.
If you've been interested in the D9200s, these are a great option at a reasonable price.

I'm based in the UK and will ship for free within the UK. If you're interested in shipping these elsewhere, please let me know and I will look into it, but please remember that you may have to pay tax/import duty.
