There are a million options out there for lavalier microphones, but which one should you get? Well, in my opinion, it's the Purple Panda Lapel mic. It's available for $24 on Amazon and comes with all the accessories you could possibly need for all kinds of shooting situations. In my testing I've found that it performs quite well in terms of audio quality. Something I also very much like is that it doesn't require any batteries for operation.
