Best CB mic made, period. Say goodbye to background noise and squeal from your talkback.

The RK56 has superb noise cancelling while offering a nice rich audio with great frequency response and crisp mid-high frequency response.

This is the mic for the true CB audio buff.

Pros: Excellent frequency response, noise cancelling and clarity. No more talkback squeal.

Cons: None

Jason - Walcott CB

Not the same mic it used to be. The current generation Road King 56 mics have moved production to China. Unfortunately, this has produced a tinner, less clear, less noise canceling microphone. Gone are the days of yore when the Telex Turner ruled the air waves.

Pros: Noise canceling and comfortable position for the push to talk button

Cons: Does not sound like it once did. Expect a tinnier, less clear sound from older models.

Good mic....

Purchased it about a year ago just because I wanted something different from the standard mic.

Pros: Handle is suprisingly comfertable, rubber mouth guard gives it a good feel and I've had no complaints about my transimission signals from anybody.

Cons: Cable came loose from stess relief on CB plug in.

Overall: If your looking for a good mic, look no further.

What Customers are Saying...

I have been trucking for 15 years and this has been and still is the best cb radio store in the country! Most of the other ones are chop shops with little to no invintory with some wanabe tech thats nothing more than a parts changer. I am looking forward to doing business with you again in the future. Thank you.
