Before he picks up sound from the PC, it sometimes detects the TV from a neighbor in the building but a push of the button switches the rule immediately on the frequency of the PC. I find it just as comfortable (ah! A helmet that does not have this faux leather!), Constantly strong and if I believed this evening he had passed away, he had just unloaded (my bad).
In short, for the price, I can only recommend, 4 years of intensive use (I'm a little hard of hearing) to all volumes, ease-of-use and robust foolproof. 5/5.
