If you Google search Reddit about the topic there have been a number of Clear pad swapping threads. Most people tend to go with stock or Dekoni but ZMF makes Focal pads as well, there just isn’t as much info about the ZMF pads.

Resolve has a write-up about the Dekoni pads and DMS has a short on his YouTube channel testing all 5 (including Stellia custom pads).

I use the Dekoni Velour on Clear OG’s and they sound pretty close to stock but I personally like the stock better, just they attract grime easier so I prefer the Velour earpads overall.
