Fostex Replacement Ear Pads model number:
These pads will fit the T20RPmk3, T40RPmk3 and T50RPmk3 headphones.
NOTE:I have been able to fit these pads to the T20RPmk2, T40RPmk2 and T50RPmk2 models, and several buyers have as well. Folding them inside out helps, and I've posted pictures of the process. HOWEVER, it's a tight fit, and not everyone has been happy with it. If you are buying these for the mk2, I recommend getting a single pair first to be sure you are happy with the fit. I do accept returns for the single pair if you wish to try that, but not when selling in bulk. Please be aware of that if you're buying these for the mk2 models.
