Got the Deluxe Audio Strap installed yesterday, here's my quick thoughts: Installation issues similar with the Initial Vive set-up. Even the official HTC Vive video on the set-up misses entire steps about disconnecting the cables from the original harness, and multiple steps in the process require such an amount of force that the fear of permanent damage to the Vive is real. Having said that, I agree with what everybody else who has reviewed the Deluxe strap has said. It's completely amazing. It changes the balance of the weight on your head from constantly pulling your head towards the ground by using a solid plastic base mount for the back of the head. It's very easy to now adjust it to fit exactly the right size by a knob on the back and because of the new balance and new sizing capabilities, I can now easily look in all directions (including up and down) quickly and easily without the headset moving or without me thinking that it is going to fall off. The headphones themselves are an improvement in sound and comfort over the earbuds and good enough quality that I no longer feel the need to wear my heavy Void headset on top of the already heavy Vive. Highly recommended for any Vive owner, it is the hardware that it should have shipped with but that's not a new problem with first gen hardware. And as far as the additional costs go, yes VR is expensive and the Vive is the most. Having no experience with the Rift or the new Rift upgrades, PSVR or any of the other offerings, I can't determine if the Vive is overpriced. But I can say that if you've already invested in a VR capable PC and already invested in the Vive, the $100 investment in the Deluxe strap is minuscule and well worth it. A Chair in a Room: Greenwater is scheduled for tonight, we'll see if the new strap allows for longer game play so I can get through the game.
