Most Yamaha info on internet about this product is wrong -- the 
mc IS an electret, and the physical packaging makes that clear. 
Dunno where the error arose -- perhaps a previous version of 
this product had a dynamic mic, or maybe the advertising "spec"-
writer did a cut and paste and blew it. Wouldn't be the first 
time. :)  Ditto with the 600 ohms part. 

What the product description SHOULD say is that it is an 
electret mic with its response tailored for communications use 
and having a very high output. The product comes with a battery 
adapter and adapter plugs to allow it to work with products that 
don't provide bias. I suspect that this product is targeted to 
computer gamers. Be thankful -- we're benefitting from the 
potentially large quantities that Yamaha expects from the 
product, hence the low price compared to ham products. 

For others who asked about where to buy -- the lowest price I've 
seen on the internet is Sam Ash in NYC. Don't know if they will 
ship abroad. A member of our club arranged a group purchase, and 
we paid just under $40. I think we bought about 25 pieces.
