Fradsham - No wind noise in my full faced helmet.
WVBassFan - I have an iPhone 4s and it works just fine. Best to look at heir website for other details.
Flash, I purchased these mainly for the upcoming CDT ride so that it would be easier to communicate with my buddy for gas, restroom, food, look out for that, look at her, hey there is a bear right behind you type talk. No chatty Cathy to worry about. My phone will be turned off for the majority of the three week trip. No streaming music, only the sound of the engine and stones pinging off of the skid plate. GPS was muted the first day I owned it. Now if it had a sexy Irish lass talking to me, I'd leave the sound on!
