Review on HyperX Cloud MIX - Wired Gaming Headset + Bluetooth, Game and Go, Detachable Microphone, Signature HyperX Comfort, Lightweight, Multi-platform Compatibility - Black by Nguyn Hong Qun  (Qun ᠌

The headphones were bought as a wireless gaming headset and the experience of using them came out very enlightening. I didn’t know that the Bluetooth standard does not imply high sound quality for input and output at the same time. When you pair a headset with a PC, two devices appear in the list: headset and headphones. The first is the actual headset and the sound quality when using it will be so-so. You can just talk, but the sounds of the game and the music will, to put it mildly, suffer. Headphones are just headphones. In this mode, the sound is excellent, but there is no microphone. And this is how all Bluetooth headsets work, which was a discovery for me. That is, it is a gaming headset and it is a wireless headset, but not both at the same time. You can play with good sound quality by connecting the headphones to the PC with a standard cable, but their whole meaning is lost for me in this situation. And as a headset for the phone (there is a transition between reception and transmission / only reception occurs automatically), they are too big for my taste. So this is a very specific model, which is only good if you fundamentally want to have an all-in-one device and a wired connection to a PC does not bother you. If you want a wireless headset for games, then take the RF.
