Works great! – GunSonics! Review

The only catch is finding earbuds that work under muffs - otherwise, save some money (despite the kings ransom of $10 in the app world!) I'm cheap, and this is worth the money. You can even listen to music at the same time, if so inclined, by starting this and then toggling the app switcher.
