Tom's Hardware published a review on the HP Windows Mixed Reality Headset
A quote from the article:

The HP Windows MR headset isn’t a bad headset, but it’s not a great one either. The product designers did several things right, such as include moisture-proof cushions and a removable tether cable. However, the negative features outweigh the positives, detracting from the overall value of the headset. Unless you get a screaming deal on the HP Windows MR headset, you may be better off with one of the competing options.
