Well, i used it for around 5 years and once it was stolen i missed it a lot. But in the end i used plug in noise filters as well as those NGs are pretty loud. Now i have a sennheiser HMEC 26 which is more quiet. However it has a pretty high clamp pressure and a very high price tag as well. And of course the 850 is very light weight.
I would say try it out. At least over here you can return everything you buy over the internet within 2 weeks, which is enough time to try a headset on the line.
