HTC Vive's Deluxe Audio Strap finally completes the high-end VR headset experience

What most people don't know about virtual reality headsets could fill a holographic stadium, but that's not slowing the competition between the leading VR headset makers. The latest competitive upgrade comes from HTC's Vive VR headset in the form of a new audio attachment called the Deluxe Audio Strap. 

To be clear, this isn't so much an innovation as it is playing catch-up with the Oculus Rift, which debuted the commercial version of its VR headset with headphones built into the device.
