Priced the headset is certainly good.
However, I could find out under Windows 8.1 is no way how to synchronize them, the volume for all programs.
It was always the case when I started a new application with sound that the sound was brutally loud.
Even after restarting any programs or their sound settings are resetted.
In Windows 7, there was no problem.
The buttons on the headset worked with me neither Windows 7 nor Windows. 8
Even prolonged use left a lot to be desired, since I * relatively * have big ears.
The pressure on the ears was very big, so it was uncomfortable after about 30 minutes already.
Have it sent back, because the main purpose could not be fulfilled. Call I have therefore no longer tried.
Bin even further in search of the "appropriate" Bluetooth headset - but I will not give up;)
