Pilot Program 3.0 mics are not currently in stock- when they are, you'll find them here http://www.modmic.com/products/modmic-3-0

Here's the old post about the differences between the 2.0 and 3.0 

Please read all instructions. The voice (facing) side of the mic has 2 slits, the mesh side is for the noise side!

Updated the compatibility table. Seems most Realtek HD drivers/cards do not like the mic. Otherwise, we seem to have encouraging results. Peter G. below comments that disabling the Realtek audio manager (and a few other notes) in msconfig has helped his Realtek situation.

Tentative Pilot Program structure:

• Price will be lower than original 3.0 price because there's a few catches...
• Buyers take the chance of having the 3.0 not work on their hardware (even if you're on the "works" list, we can't be completely certain that it'll work perfectly, hence the pilot program...)
• IF IT DOESN'T WORK or you aren't pleased with the sound: buyers have option to swap out 3.0 boom with 2.0 boom but MUST PAY SHIPPING AND HANDLING ( 6 USD domestic, 13 USD international) - this must be done shortly after you get the mic.
• We can't really offer  a warranty for the 3.0 because we may not continue it. So, don't break it!
• Pilot buyers must come back here and comment on their hardware and experience so we can add it to the list. Depending on results we may expand the 3.0.
• If you buy a pilot 3.0 you're saying that you've read and agree with all the 3.0 instructions and "rules" 

1. We're just using the 2.0's packaging for the pilot mics.
2. The mic tip has two sides- the side with two slits points toward your mouth, the mesh side is to pick up background noise.
3. The clear plastic clip (clear plastic is much stronger than the black, otherwise we would have made the clip black) on the cable is to keep the cable dangling from the clasp spot, not the end of the boom (http://www.youtube.com/watch?feature=player_embedded&v=GgkbXCCLnUU#t=64s is what I'm talking about). This way the dangling cable doesn't move the boom in the clasp. It's not intended to connect to other cables.
4. Some beta testers claim that their mic is very quiet and has a lot of noise once it's amplified. I think this may have to do with Realtek drivers (here's possibly the fix). When we have them return the mic for our testing, it performs fine. 
5. The 3.0 can't be bent at sharp angles; it will kink. Try not to bend near the tip of the mic. If you want to try to bend it at a sharp angle/radius, it is best to bend it around an object with the same desired curvature e.g. broom stick.
6. The 3.0 clasp is the same as the 2.0 clasp. The boom can be lengthened or shortened depending on where on the boom you place the top clasp.
7. The 3.0 mic capsule is sensitive to breath/wind, so we find it best to position the mic tip facing the corner of your mouth, 1-3 inches away directly to the side of the corner of your mouth

Here's what we've got so far.  NOTE- WINDOWS 7 OR 8 SEEMS TO MATTER QUITE A BIT. PLEASE INCLUDE YOUR OS INFO!
