This review is from: Parrot Zik Headphones Hard Shell Case with Zip Closure (Wireless Phone Accessory)
Technically these are very very good and also appeal to gadget nerds everywhere. Plus they look really good and are brilliantly comfortable. Very easy set up with an HTC One.
What's not to love?
Oh, the price. That's not to love. Positively makes your eyes water. But build quality and technical capability mean it's not that unreasonable.
