I still have headphones for about a week, and during that time I can say that the headphones have a very good workmanship, perfect sound (provided you install the iCue software (the application is in English), in which you also control all the additional functions of the headphones and play with sound equalizer), fits well on the head, and overall has a premium (corresponding to their price).
In my opinion, these headphones are suitable for people who use their full potential, ie. for people who, in addition to playing games / watching movies and listening to music, also often call on a computer, because the headphones have a perfect microphone with (adjustable) “sidetone“ function, which is actually playing your own words into headphones so you don' t shout when speaking because the earphones it dampens the sound quite well. If you do not use all their functions, I recommend other headphones.
The headphones can be used wirelessly via a USB-A receiver, wired via USB-C to a USB-A computer, this way they are also charged, or via a 3.5 mm jack, e. g. to the phone, but the microphone does not work when connected via Jack. The headphones have an audible signal to turn the microphone on and off, as well as a low battery signal that sounds once, not repeatedly, so it doesn' t interfere with a low battery, unlike other headphones. Signaling is a female voice that speaks English, signaling is not unpleasant for me. The headphones have RGB LEDs on the sides of the corsair logo, which can be set to one permanent color or different motifs that change colors, or turned off completely for better battery life.
As for the negatives, I would just like to mention that they are not 100% comfortable, sometimes after a long period of use pushes from the top of the head, but it may be because I have a narrower head, but the padding in the top frame of the headphones is pretty soft . It' s definitely not something I would return the headphones to, otherwise complete satisfaction for me.
