Its price is 300 on Amazon.
Very clean use and well-maintained.
I use it and return it to its box.
It doesn't have any problems except for a small thing: if you control the volume from the headset, there's a slight crackling sound (rare) that only you hear and it goes away, it doesn't persist, and the mic is fine.
Very comfortable for long use.
