No experience with these though.
Heva, Ycoop would like to have cards. These are omni. It looks like these mics are made from a Primo EM172 capsule. I am using these capsules for recording lectures. Their advantage is that you can place the microphones where you need and are unobtrusive. I think there is not a big difference in quality compared to internal microphones. I would not use them for recording music. I think people are using them for ambience taping.
What's interesting is their phantom adapter. This could work with Chris Church microphones. For AT lavalier microphones, it is better to buy an original phantom adapter. (It looks like the producer is from Slovakia. It is nice, Slovakia is our neighbor.)
I would advise you to buy Chris Church or AT lavalier mics. Chris Church mics are designed to be powered via 9V battery. Then you will need reduction form stereo jack to two XLRs. Or you can try the phantom adapter from the manufacturer Heva refers to. But I cannot promise for sure that this phantom adapter will work with CA mics.
If you decide for AT mics, you can power them via original phantom adapter or 9V battery box. If you are taping loud amplified music AT mics need modification when powered by 9V battery box. You can find more information about this modification - look for 4.7mod in the forum.
Here are a lot of posts about these mics. You can find a lot of examples how these mics sounds on Live Music Archive. Look to yard sell here too.
I'm also told the tascam needs balanced mics. Ive no idea what this means - are these mics balanced?
Do not worry about balanced and unbalanced connection. Balanced input means you can do both balanced or unbalanced connection. Most of lavalier mics have unbalanced output so you will have unbalanced connection. When using short cables to the microphones, nothing happens when there is an unbalanced connection.
