Which Headset Works Best For Skype On A Mac?

I’m currently looking for a headset so that I can Skype on my Mac.

Funnily enough I already have “a” headset, but the connectors are the wrong size, thus rendering it unusable. For sanity’s sake a USB connection might work better, though I could be completely wrong about that.

I want something that is compact enough to fit in my laptop bag and offers good audio quality (VOIP can be taxing enough without using shoddy equipment!)

I’m not overly concerned about the price, as I’d prefer to have a good quality product that lasts, rather than something that breaks after a couple of months.

Any and all recommendations open!
