This mic is a large diaphragm capsules mic. The AKG 420b is more of a newer style then what it use to be in with the previous models. Some of the features of it are, a switch able bass filter that can cut and minimize noise. The mic itself is pretty rugged and can take being dropped or dinged up a few times and still keep working fine. I have had one of the AKG 200 versions mics and dropped it before (years ago) and it stopped working almost instantly. Something must have just got messed up on the inside of it and I didn’t even bother getting it fix just gave it to someone else. But with the 420b by AKG seems to have put a lot more time into it making sure that it is a lot tougher and can take more.
The AKG 420 is pretty flexible and it will give you pro studio quality right in the privacy of your own home. It takes a 3 pin XLR cable or output which is standard and most all interfaces have those connections. You will appreciate the sound you will get with the 420.
Overall, there are a lot of mics on the market that are affordable. Some cost more than others, but once you find one that will work for you , you will stick with that brand and particular mic. The AKG 420b is one of those type of mics that once you try it you will be hooked. The mic will cost less than 300 dollars now new, and is still being sold at all major stores. AKG has a few more mics that are worth the money too but they are a little more expensive. If you want to go with AKG this could be the best most affordable mic that they offer as far as around the head mobile mics go.
