Helmet of choice for K2 Pro Sean Pettit.

Think of the K2 Phase Pro Audio Helmet like a lightweight tank with luxury-car-like upgrades on the inside. This durable, quality helmet meets industry standards and certifications to help protect your head during a sudden crash, cartwheel session, or bonk on the head from a chairlift safety bar. Active matrix venting technology enables you to regulate the airflow of the helmet vent system with the touch of your finger (think climate control with the flip of a switch).

Its K2dialed fit system features an ergonomically inspired three-point adjustable interface to maximize fit and customization with the twist of a dial for superb, on-the-fly convenience. And you're going to dig its removable, washable full-wrap liner system that wicks moisture away and supplies breathable comfort when you haul butt down the hill. If you're worried about a gap between your goggles and helmet, don't be, as the Phase Pro's universal brim design works seamlessly with K2 goggles and most industry goggles.

The Phase Pro's baseline audio level 3 sound system brings your tunes to your ears and connectivity to your phone when you shred or chill on the lift. Its integrated headphones and on-cord mini-mic connect to your cell phone or your MP3 player for easy connection while you tackle a gnarly line or spin yourself dizzy in the park.

Speakers Are Awful

  • Familiarity: I've used it once or twice and have initial impressions

I'm returning this. Audio quality is non-listenable (made that word up)

Nice feeling helmet. Speakers suck!

    The helmet itself is very comfortable, The speakers are terrible! Zero bass. Hoping I can replace the stock speakers, as they are pretty much worthless.


    • Familiarity: I've used it several times

    This helmet comes with all the best features- compact, sleek looking, and an excellent audio system.


    Great Value

    • Familiarity: I've put it through the wringer

    Held up well over two years. Keeps the head warm and the sound is good.

    great helmet

      the helmet is nice and sturdy with a tightening knob in the back which is useful.

      the call speaker in the extension cord didn't work for me but i think that's just the cord.

      the only problem i could point is that the helmet doesn't breathe as much so it can get a little sweaty, but due to the moisture absorbing covering it still alright.

      Nice speakers, cool helmet design.

      • Familiarity: I've used it several times

      Lovin it already. The speakers are surprisingly high-quality, which I didn't expect out of some stock helmet speakers. The little volume control is cool too, so you don't have to constantly take out your phone. The helmet itself seems sturdy enough and has a cool fit and design to it.

      I didn't give it 5 stars because I haven't had it that long and wanna make sure it's durable beforehand, and also, I can't seem to get the little Pause/Play button to work for my iPhone4.
