Received mine today Elite Hybrid and Fenestrated Sheepskin (FS). Installed the FS. The removal tool made uninstalling the original pads a breeze, acouple of minutes each. Uninstalling the FS is a different story. After installation, the sound was muffled so I read comments below and I realized that I needed to remove the original dust covers.
This is where the fun or “frustration” began. I was able to separate the FS pad from the ear cup with the tool again, yet I was unable to remove it completely because of fear to damaging anything. The FS pad was firmly installed in most of the earcup. Luckily, the space between the earcup and pad was big enough for me to use a pair of tweezers to remove the original dust covers. In addition, the tips of my fingers were black from the dye - hum, quality control issues???? The removal tool is pretty beat up too.
The sad part is I purchased two earpads to try and now I am not sure if I should try again to remove the FS and install the hybrid.
I have a HD 800s. Has anyone else experience the same issue? And yes, there is a slight chemical smell. Good luck. Not sure if I would recommend these if this difficult to remove until resolved.
