I agree with Brian. If you get a chance look at some of Deck Officers videos he made in his Track T. Going down the highway at 90 MPH and you can hear them talking in their regular voice as there is no wind noise. Also some of the Cobra guys want the sound of the Cobra to be louder and you can place an external mike where you get the sound that you want. You may have to buy an extension cord that plugs into the regular cord though as I think it is only 6' long.
