Excellent, I use it for Skype calls and listening to music using my PC.
A wee gripe is that the headset keeps slipping off my head (perhaps it is my head which is faulty!).
A special well done to Logitech is in the quality of the headset cable, robust and well able for the job. I mention this as, sadly I have bought other makes, and had issues with their thin, flimsy cable, which inevitably broke, and annoying to think that some of these 'reputable' manufacturers had skimped on a vital component, like a cable, to save a few pence.
My pc uses Linux Ubuntu, and the USB connections and access to programmes for the headset were effortless.
