Before that I had 450 and the headband broke. I had this for 2 days and the headband broke. I have to say DO NOT BUY! Until BluParrot can make the headband and the electronics built into it, skip this one! Also, this headset has a significantly lower volume than the 450, so it's barely audible in any ambient noise. Also, the battery no longer holds a charge. Less than 4 months!
