I bought this to run purely from my xbox one x console with the optical cable to drive my Massdrop PC37X headset. The headset is 50 ohms and is barely loud enough for my liking when hooked up to the controller. Hence this purchase. And it's fantastic! Sound volume is as loud AF and adds extra boom to the bass for all explosiony (?) things. The only issue is a small amount of distortion that comes and goes that you can hear when it's silent and every now and then with severe changes in game volume happenings such as explosions etc. It's notiecable but brief and tolerable. I mean, it's $25. Totally worth it if you're looking for boosting your decent gaming headset and if you aren't a fan of controller connected headsets. Also, if you're a couch gamer playing at 6 ft or more from the tv you will need a longer headset cable or longer optical and usb power cables. These two that come with the unit are only a couple of feet long.
