The audio quality is pretty good for the price, and it's very easy and convenient to attach to your shirt, but unfortunately it's not very compatible. Unless you have an iPhone or iPad, chances are you won't be able to use this microphone. As of now (July 2017), it's still not compatible with many Android/other devices, which basically makes it unuseable.
With all that said, if you have a iPhone/iPad, this is a pretty great buy!
