I caught a killer sale before Christmas and got an Omen with a HP Mixed Reality Headset. While the Vive and the Rift have more game options and a little better tracking, this thing makes a great entry level set. Its easy to connect, it works well with steam, and doesn't require a ton of usb connections. 1 hdmi and 1 usb connection and you're good to go. There's also no need to put sensors all over the play area, like with the other guys.
I am currently sending this back to HP to have fixed, my kid used it so much he wore out the connector coming from the headset. It's nice that it unplugs for storage but it seems like since the headset is essentially tethered by this cord it would have been more prudent to have it built into the headset with tons of stress relief. Instead, there's a short cord coming from the headset with a female end. The male end that plugs here is pretty secure but from just 5 months of use you can see a fair amount of wear. Finally, and the reason I'm having it sent back, the female end is a little bigger, causing movement and a disconnect from the computer. In my case, the wear was so great the movement actually bent two of the pins on the inside of the female connector. I had a heckuva time explaining this to the HP guy on the phone, but finally convinced him it wasn't the cord from the computer that was the problem.
We'll see if they fix it, or try to screw me on warranty (there's a 1 year warranty on the headset, that doesn't cover "abuse"). Hopefully, all will go well. if not, I'll have an excuse to go VIVE, although since this is used in the living room i'd hate to add a bunch of sensors all over the place.
