Excellent Build Quality - Solid Heavy duty construction. Unlike the product photo, the stand I received actually came with dual side by side screw clamps. Monitor adjustments require a lot of tightening however and after adjusting everything you can't adjust anything without the included Hex and box wrenches. The adjustment bolts needed to be tightened very tightly. I would recommended leaving the adjustments alone once you have the desired setup. Additional base mounting option of drilling through your desk is also included. Independent monitor height adjustment is not possible so if you want your monitors to line up horizontally, I would suggest getting the same model monitor.
I've been using two of these weekly since November, and I must say I'm very impressed for the price. I managed to fit my AT2020's in them, and they're snug, but it works. I love the integrated XLR cable, keeping everything clean. They're not too small, and when fully folded up are nice and compact, they don't take up excessive desk space when not in use. My only complaint is that they seem loosely attached to the bracket/clamp that attaches to the desk, no matter how hard I twist the knobs. this leads to a "wobble" when you adjust the stand, which is a bit annoying. But all in all, very solid for the price.
I use it paired with a tablet or phone. To get the most volume from the headset the root/main device volume needs to be maxed out. Some bt headsets will also change the root device volume which limits the volume from the headset but this is not the case with these ones. It may also depend on the device. When they are paired and music is playing, change the volume on the headset and see if the root device volume appears on screen and changes with it.
