Wow.  Great hacking there.
Now we finally see what is inside.
These look like they would be great for outdoor festival recording.  All those times you get caught in the rain.  Worry no more, your microphones are still safe :)
Please DO NOT mail me with tech questions.  I will try to answer in the forums when I get a chance.  Thanks.

Thanks Richard.

Do you have any idea what SPL's these can handle? There are three wires, but two are tied to each other, so basically two wire mics.

That's all I'm worried about is that they'll overload.

Plug in power, mic sens LO, level #2 on Sony PCM-M10.124dBrms @ 250Hz calibrator is just under maximum level.A pure sine wave, no distortion.
These things are not going to distort is my guess.
Perfect for plug in power.

I do like the RCA notion.  I think you did well in the mini-xlr end cap, rather than trying to build them into the rca connector.

On the wire, I practiced on the cut-off cable, and found that my fingernails did a decent job of stripping. I was able to get the wire exposed. In tinning them, I noticed that the solder just sort of pushed the insulation aside as it wicked into the wire strands.
I also used a razor blade and pushed my finger lightly against it with the wire trapped in between.  It took a portion of the insulation off, as it sort of pigtailed; but also appeared to take some wire with it.

Speculation:
Maybe not totally necessary to strip the insulation?

I also found a pair of nail clippers helped in removing the kevlar thread.

I had a chance to test the Sennheiser MKE 2's against my favorite omnis, the Audix CPS-MICRO-O.

The MKE 2's where punchier and less open sounding. They had better bass response that the Audix mics and on some material sounded truer to the source. Not as hyped as the CPS-MICRO-O's.

I ran them into a Core Sound battery box, which does not supply gain.

I noticed a few interesting things while testing.

They didn't need a mic pre-amp at loud, but still home listening levels. I just ran them straight from the battery box into my Mixpre 6 XLR inputs set to line in.

The phase was reversed compared to the Audix mics and my Microtech Gefell M300's.

They were very well matched in frequency response , but ~2db off in output.

I think the Sennheiser MKE2's  are going to be an excellent addition to my microphone arsenal.

It's good to hear your impressions.  One question I have is whether you were using the Sennheisers stripped from the bodies (like in the picture you recently poster showing the cap without the grid/membrane)?

Also can you expand on what you mean by "punchier?"

Hi heathen,

I used them with the grill and membrane in place as pictured with the RCA connectors on the ends.

The Audix mics have an airy quality about them. More top end with slightly  scooped mids. The MKE 2's are fuller in the mids and sound more centered and not as airy in the top end.

To get an idea of what the Audix mics sound like:

I'm going to test these on Friday night at the Lil' Smokies show here in Atlanta. I'm really looking forward to seeing how these sound, especially if they work with PIP.

I just spoke with Sweetwater, there are quite a few left, WS for $10 and mics+WS for $20.
I'm going to build a few pairs of these for outdoor recording/ surveillance type applications.
If anyone wants to dis-assemble them, take off the protective screen, the raw MKE2 capsules might sound a little better without the cover.  I have not experimented with this yet.  Happy to build a few sets of "waterproof"/"windproof" mics for now.
I just bought a few more. Thanks again to members of TS.com for the connection :)

I did too last week.  It's just too good of a deal to pass up.  For $20 each I can make several pairs, each purpose-built for a specific function.

Richard mentioned the waterproof membrane. Has anyone attempted to remove this yet?

I've got a couple of sets of these and I'm scared to death to deal with these tiny wires. Anyone in the mod market to do up a set for me?

Also, props to Sweetwater. Not the first dealings with them, and their customer service is top notch.

Hi lsd2525, that membrane is part of the plastic/wire mesh section that can be separated away from the element. I haven't tried to remove it.
