Hey guys just have a question about helmet headset setups. Have been looking into getting some speakers for my helmet and a mic to use on a two-way radio, but after a lot of looking around I got a little confused with all the different types out there. Basically all i want to be able to do is listen to some music but have it setup so if i key the mic or someone else is talking to mute the music. When reading about the different types of setups there seemed to be a lot of talk concerning what could work with what and lower and upper cords not matching. So basically is there anything relatively cheap out there that can hook up to an mp3 player and a simple two-way radio(that has a remote key i can toggle on the handlebars) that i can fit in a full face helmet? thanks for the help.
