Microsoft Store offers the V-MODA Crossfade LP2 Limited Edition Over-Ear Noise-Isolating Headphones in Matte Black for $99.99 with free shipping. That's the lowest total price we could find by $49, although we saw them for a buck less three days ago (since expired.) Features include 50mm dual-diaphragm drivers, exoskeleton case with carabiner, SteelFlex headband, and detachable Kevlar-reinforced cables.
