Samsung has announced new headphones branded and optimized by AKG. The Y600NCs are the more premium of the two, and come with active noise cancellation (ANC) and an innovative rotating ear-cup for volume control. The Y400s, on the other hand, are smaller on-ears that come in a fresh range of colors.
