I have never used one but I think that they are on the lower end for quality when it comes to motorcycle audio.
What to buy depends on what you are looking for and what you are planning to do with it. If you have a cruiser, are you simply looking for music? Are you looking for an intercomm system? If you are simply looking at head sets, I would also look at J&M or Show Chromes headsets before making a purchase. While the Chatterbox items are very cost effective, you get what you pay for when it comes to audio equipment.
