This is the latest in a series of sound systems I have used over 50 years from Astraltune to Sony Walkman and shock-proof CD players to IPOD, bunch of different headphones and eventually the headphones that go in the helmet with a wire with way-too-small-for-my-mittens on-of switches. This last transition had two goals (1) to get rid of the earphone wire so that the iPhone could get away from the cold and (2) control the volume and play/stop/rewind without having to take off my mittens. From that perspective these are great. The thing pairs with my iPhone very nicely, the buttons are very intuitive and easy to get to, and as an extra bonus I don't have to dig my phone out of my pocket to talk to Mr. Spam Likely when I am on the slopes.
One thing that could be better at least for my helmet is that the recharge wire pokes out of the headphone so to make sure it wont break I need to disconnect it and then take the thing out of the helmet to charge it. It would be nice if there was a way to recharge the headphones without having to mess with that but that is not a big deal really. This is a long way from strapping the 3.5lb Astraltune on my chest not to mention the earplugs and plus the sound quality is great!
One piece of advice if you are new to this: Keep the volume down so that you can still hear the wind (and the snow boarders) but most importantly remember the bumps are not evenly spaced so don't try to ski to the beat of the music. Ski to the melody or the Cadence if you want to be fancy.
