I don't know if such a thing exists, but I'd like to be able to listen to music on my phone and answer my phone on the bike. I want my earpiece to be an earbud for the sake of external noise attenuation. Does this exist and if so can you give me some reviews and some links. Also, what mouthpiece would you recommend. I am an e-tard the likes of which you have never seen, so please frame your responses in a very non-technical manner. I know NOTHING about this. I have an old flip phone and may upgrade if I can get what I have described above for a reasonable price.
