I picked up some of these over the weekend. Cardiod type with 6 holes around the outside of the PCB, and two solder pads. The rolled aluminum case is a hair under 3/8" dia. and overall length is a hair under 1/4". Only identifying mark is 'CA' embossed on the side of the case. They seem fairly quiet. I wired a pair into a binaural headset, but haven't had a chance to record any music with them yet.
Anyone familiar with these? Thanks!

Thanks for that info. Yeah, strictly speaking I shouldn't have said 'binaural'. Really 'X-Y with a head stuck in-between'(!) It was just see if they worked, to get a rough idea (conclusion: fantastic, considering the price).
Any recommendations for their best use?
cheers

If it's the same quality as WM55A, could be used for lots of things, it's a very respectable capsule, probably the smallest good cardioid. With a proper circuit, it makes a good high SPL close mic for drums. You could build a mini-ambisonic mic. Anything, really.
Thanks, that sounds promising. They're quieter than I'd have expected just on the Sony's jack power.
I pulled them from NOS Sun Microsystems computer mics. Apparently the mic housings were assembled in the UK (now I wonder does that put a Euro spin on the cap origin?) Cost me under a buck each at the last ham radio swap. ;D Wish I'd got more now!
I might try a pair in a vertical X-Y. I expect each cap will want the right amount of baffling from front to rear. If they sound alright, I'll put them on 9V and go and record some music... :laugh:
cheers

thanks ms. I guess 9V is the only other thing they might need. Could you link me to a simple preamp schematic I might try if I wanted to run them on longer cables?

Thanks, that looks perfect.
