Wear regarding the HD660S: the fabric colours have bled since I wash them every season, I have new earpads I compared to the HD660S and they're only a few millimetres thinner near the center in comparison. No channel imbalances detected, they run fine as if the day I got them.I stretched nylon over the drivers. They look much better in person and IMO are a lot more comfortable than the foam lining. I've included the foam inserts should you wish to use them instead.

I live in the GTA, if local would prefer to meetup in an area closest to the TTC, or near a location that is easily accessible via Go Transit Line. Price will not go lower if local.

Owned the HD660S for a year, purchased from eBay from an official dealer. The plan was to keep the HD660S as a gaming headphone alongside the HD600 for music. Plans changed though.
