I used the chips last year pretty extensively, but not so much in the way they were intended to be used as my helmet doesn't have ear flaps to put them in.
Instead, I threw them on under beanies and outside by rolling the ears up so there'd be some beanie between the speakers and my ears, as the material of the speakers is hard so it does press on your ear and hurt after a while if you dont have a soft layer between it and your ear.
First of all, the sound quality is pretty awesome for a pair of helmet earphones, best I've heard actually.
The controls are really easy to use, although pressing them means pushing them to your ear and they do go pretty loud!
I didn't test the mic much other than to skype my girlfriend, but I don't think there was much issue there, so i'll say the mic quality is decent. Pickup wasn't too great but it's way better than having to fish out your phone from your pockets haha.
One issue I had at times was with the connectivity of the bluetooth, although it most likely was my phones issue. The battery life is pretty great though, It can go a day of skiing pretty easily I'd say.
Overall, they're really damn durable and have a solid weight to them and have pretty quality sound. For something to toss in if you've got ear flaps meant for speakers in your helmet, I'd definitely recommend it, as it's an upgrade to the built in ones for red helmets and such.
