HBH-PV-715 seems to be the cheapest of the three, and is - once again, in my opinion - the better looking of the bunch as well. It’ll come in either the pictured white trimming or a black one.
HBH-PV-720 is the headset for the more sophisicated and fashionable of us. You can personalize its look with StyleUp covers, and it comes with a pouch and a silver necklace.
HBH-PV-740 is the professional headset for the business man or woman. It’s the only one of the headsets to feature a status display, and it’s the only one to come with a headset desk stand and USB charger. Apart from that, you also get the silver necklace with the HBH-PV-740.
