Sure, that's literally how I started both comments but I can try to clarify a bit more my point : if you want to "just" use, this isn't great, but if you enjoy building itself, it might be even better.

FWIW I do both, including professionally, so I definitely get the point of making a headset, or anything really (I even do a bit of woodworking and welding) yourself or building thanks to the previous projects of others. I'm definitely NOT suggesting it shouldn't be attempted. I'm solely warning people who are solely, or even mostly, interested in a usable object while investing minimum effort in.

I second utopiah's point, if assembling one with your own hands sounds like fun to you, go for it. But a second hand Reverb G2 from ebay will almost certainly be both cheaper, and better for using it in almost every way, it would even have significantly higher resolution.
