This is my first bluetooth headset, so I can't compare it to others, but I think it's a great product.  It's comfortable to wear, so much though, that I forget I'm wearing it.  It paired instantly with my Blackberry Curve.  The volume could go a bit louder, but the sound quality is great.  And others have told me that they like to hear me speak through it rather than directly to the phone (much clearer for them).
