Hi IO540,
Well........ for the 30-40 minutes that they work properly, I DON'T have any issues!!
Sound quality is good - everything is much clearer.
So... I've got no problems with Pilot who are quite prepared to get me a refund, with no quibbles, if we can't resolve the problem - but I WANT to keep the headset and find a cure, because I like it.
I'm more interested to know if anyone's enountered any compatability isses with other headsets or can think of something which could cause the almost "timed" problem in the first place.
