Razer Kraken Tournament Edition replacement ear cups

Hello, Id like to ask if anyone knows any replacement cups for the kraken tournament edition headset, since mine are starting to tear and the cushion is about to fall off. I have contacted the support whether they are going to restock the replacement cups or not, and they told me they do not have any plans of doing so. Id be most grateful if anyone could tell me about any replacement cups that are compatible with the headset. (Also Im from Czech Republic, Europe so US shipping only sites will not help)
