So, is built-in talk back on any given CB Radio a perfect representation of what you sound like over the air, or is it pretty much deceptive? I have used talk back in two different ways. 1. Using headphones with the radio's talk back, and 2. Using headphones with a walkie-talkie that is close by, and the the audio is very different between the two. The talk back audio from the radio is crystal clear, with a wider audio response, and zero distortion, and the audio I get from the walkie-talkie has a more narrow audio response, and has a bit of distortion. What's the reality here?
