I purchase 2 pairs of the ear pads together with my headphones. It took me years to have to replace the ones that came with the headphones.
The great part about those is that they are incredibly comfortable and durable! The only con is the difficulty to install, however the it is mounted on the headphones is do good that they will never be apart unless I want to replace the pads again.
You cannot tell the pads have been replaced! It just looks cleaner.
