Anyone knows how long the pads will last before they get worn out? Mine felt like it's gotten a little bit flatter after few months of regular use
It really depends on a lot of factors as @RickB noted, for me mine are still new looking after 2 years but I only use the HD-650 for a few hours per week, I bent out the headband to reduce the clamping force, usually have the AC on (quite humid here in Hawaii near the ocean) and have few other headphones in the listening rotation.
