CK12 Capsule - A precise replica of the renowned CK12 capsule.
The creation of the CK12 Capsule has been a long-term project of FLEA microphones which began 15 years ago. The idea was to develop their own version of the CK12 which was originated in 2009. During the course of development, the discovered an exceptional capsule from another manufacturer, the CT12. Impressed by its sound and performance, they temporarily shifted focus, setting aside the CK12 project in favor of using the CT12 for several years. It proved to be an excellent product, and they were pleased with the results. However, their dedication to completing their own CK12 capsule never waned. After years of meticulous work, FLEA Microphones is proud to announce that the CK12 is now finished. This capsule is an exact clone of the original CK12, faithfully recreating its remarkable sound quality. By keeping production under one roof, they can fine-tune each capsule to perfectly match the specific requirements of each microphone, ensuring optimal performance. The FLEA CK12 is a true reproduction of the original, engineered with exacting attention to detail and manufactured using the latest precision machinery. Every capsule is hand-assembled and tuned to ensure the highest level of performance and sonic accuracy.

Wow!
Nov 3rd 2026Well, since there are no reviews yet, I’ll give my take. I was in need a good vocal mic and my budget was moderate. Had tried most within this price range already so I was pretty reluctant to give this mic a try. The no tube thing was throwing me off along with the lack of examples online. I’ve never used any mics from Flea, but they’ve got a pretty good reputation, plus I trust Front End audio and their service. Well needless to say, this mic surprised me in a very pleasant way. The packaging, craftsmanship, and more importantly, the sound of the mic, was all really impressive. You can tell Flea put a lot of time into perfecting the details. I’ve used tons of mics from Rode, Manley, Neumann, Sony c800 ect, and this is right up there with some of the best. I believe that this being a FET mic is actually an advantage as well, especially if you’ve already got a tube pre or compressor. No fussing with power supply or warm up time. So, for anyone on the fence, go for it! Obviously everyone’s ears, voices, are different. But I’m happy and I think it’s a very fine example of that 251 sound. Special thank you to Shane for always being so helpful and patient. Also to Jesse for the kind words and getting it shipped out the door so quickly. This is why I will continue to shop at Front End. Hope this review helps someone in the mic search!
