Radios for wingmen

[Ice Cold]

Have you seen the super small radios in the movies? The little ones that go into your ear?

Do they exist in real life and how much do they cost?

I believe some of the actual ones used by the FBI run for $1000USD+. But for the rest of us, there are Motorola SRS radios with earbud headphones, which get the job done.
