I'm curious. I have several phones that I've switched stock pads for fenestrated leather, and been very pleased.
Why would one change OEM hybrid pads, for 3rd party hybrid pads?
In my opinion, the stock Arya v2 pads are very good. Comfortable, fantastic sound.
I purchased Dekoni fenestrated sheepskin for my DK Aeon 2 open phones. I can just barely stuff my ears into the cups.
One of those "oh well" purchases. I had a new pair of stock pads (with that damned "plether"), but I wanted natural sheepskin.
