I have the ATH-M50's and love them. I have noticed that on the ear pad the part that covers the driver, has a yellowish brown tint to it I think in the spot where my ear touches the driver. It's on the inside of the pad, not the pad part itself. I'm assuming its sweat or ear wax or something of that nature. How should I clean it. What should I use and what things will damage the ear pads?
Also side note how can you replace the headband? Can you do it yourself? Can you send it in to audio technica and have them replace it? How much will it cost? Mine it not bad yet I'm just looking in the future.
