The Bose headset BT series 2 is excellent but a lot more expensive.
I'm going to 2nd this recommendation. It's more than I wanted to spend on a headset, but my old RIM HS500 wasn't working as smoothly as I liked and I always hated that it didn't have volume control directly on the headset.
So I bought the Motorola HX550 because of recommendations here. It worked fine with Siri and I liked it has volume controls on the headset, but it didn't do as good a job with background noise (talking to others) as my RIM HS500, and it also didn't have the variable incoming noise adjustment like the HS500. This is when you are talking to someone else and you come to a stop, the incoming volume of the headset lowers, and then it increases as cabin noise around you increases.
So I returned the Motorola...once you've had this variable adjustment you can't go back.
The Bose is FABULOUS with Siri, working flawlessly, the background noise elimination is better than both headsets I've referenced...I mean I left voicemails to myself driving down a concrete freeway at 70 miles per hour and literally couldn't hear the background noise. And the volume auto adjust is great, too.
Sound quality is the best I've used for music, audio and talking.
The ONE thing that bothers me about this headset is battery life which is rated at 4 hours I believe. I far prefer having a headset with a longer battery life because I don't use it every day. For me it stays in my purse until I need it. For headsets that last 6 - 9 hours I can use it off and on for 3 - 4 weeks before i need to worry about recharging. I think the Bose I'm going to have to worry about at least once a week.
Still, it's not often I'm willing to deal with low battery life for a device. In this case I am. I only hope the next model is as good as this one PLUS better battery.
Very happy camper. Again, I understand the cost is significantly different than for the other models discussed in this thread, but I'm not regretting the purchase.
