The capsules are small so they would theoritically be easy to stealth, but the AKG active cables for this line are so expensive that it is not really worth the money investing in this setup if you just want to stealth. You would be better served by getting dpa 4060 or 4061 mics and stealthing with those. The dpa sound better, are smaller, and would probably cost about the same amount as ck9x + AKG actives.
