I purchased this so I can use the same set for my cellphone and my laptop.  People have already reviewed it for cellphone use so I'll just talk about laptop use.  I'm an attorney and I use this at court.  It allows you to be funcitonal while being discrete and quiet.  It connects without any drama.  I use it to check voicemails from Vonage, either with Skype or by checking my e-mail account that I have the voicemail sent to.  And when things are reaaaally slow, I even use it to listen to some music on my laptop.  It's mono and tinny, but hey, it's something.
