The range of headsets is 10-12 meters.
So the positive I can say that the design looks good as well as the weight. The battery life of 15 hours is garantier.
The negative is that after a time my microphone on 'scrape' is. I was also in the TS said that it is intolerable when exposing times. I tried to fix this by disconnecting and re-connecting that did not work.
Headset is actually top the player even if man alone but plays in TS definitely a minus.
