Hi Folks, new to the forum and would appreciate any help you could provide. My riding buddy and I listen to MP3 players while were riding with earbuds under the helmet. We want to be able to use FRS radios though and have the audio combined so when we get radioed we can at least notice it and turn down the music. Is there any kind of device that will combine the two signals that does not cost a fortune. Seems like a pretty simple task but have not been able to find much of anything on the web. Searched this forum for MP3 and got nothing but forgive me if its been discussed before. thanks
