Before I bought this headset, I researched a whole bunch of others first, and upon seeing some very mixed reviews on the various headsets I found, this seemed to do exactly what I wanted. But since actually buying this one, and having used it for some time now, I can actually confirm that this one is FANTASTIC!! It plugs in with USB, and I never have any probems with it! It's really comfortable, plus the sound quality is superb. It can be used in cnjunction with either skype, msn, yahoo, or anything that requires either speakers, headphones, or microphones. I play my music from the pc, and use these as my headphones all the time! But initially I bought this so that I can go on msn and speak to people whilst having my hands free to type. This was also perfect, because it even has a button to automatically call people on your msn contact list! Also, next to that button, it even has buttons for the volume, and also to chose whether to use the microphone or not. It has been absolutely brilliant! Just thought I wwould share that with you all, in case you were looking for a good one too! Money definately well spent! Full Marks!!
