I really never knew Bose was making these BT headsets until I began a search for the best one a few days ago. I currently own a Jawbone Icon, Blueant Q2 and a couple of high dollar Plantronics headsets. All are very good at something and not so great at others. IMHO the Bose Series 2 has gotten it right.

First off fit is everything to me. I have a set of Bose headphones, with the same designed ear piece, and I love the fit so I was hoping this would be the same which it was. Just make sure you use the correct size, start with the headset turned down and just rotate it towards your mouth. The soft rubber piece slips right under the middle fold of your ear, holds it very secure and you will not know it is there.

Second is sound quality. I am talking about outgoing and incoming, clarity and volume. The volume of this ear piece is special. I know that sounds flaky but I have had enough of these headsets to know that most do not have adequate volume if your hearing is not like it use to be. Absolutely great with this headset. Noise cancellation is also top notch. I have not tested it in a too many of different environments, but have done things like driving 70MPH with my window down while leaving a message on another phone. Also I will crank up the music while doing the same since other voices can sometimes cause issues. So far, I have not been disappointed. The messages I listen to are right up there at the top of all sets I have tried and probably surpass them. Incoming clarity is just as good. First off, they are Bose so listening to music from your phone (if you have a phone that allows this) is superb for a BT headset. I did have some slight static on calls when I first got it. I went ahead and removed the Bose from my iPhone 4 memory and rebooted the phone. Then did the setup again and I no longer have any issues at all.

Third is battery life and options. I don't really know about battery life yet so I cannot comment. Options is a personal thing so I will explain why I was looking for a BT headset that did not have built in voice commands. I have a new iPhone 4S arriving tomorrow and if you have followed this at all, you know about "Siri". It is Apples new, and extremely advanced, voice recognition/personal assistant. Since I will be working with this a lot, I do not want the extra moves needed to get me to the phones voice commands. This set fits the bill perfectly.

Oh yeah, one thing I really like (and I know others do this as well) is the ability to wear this while using my iPhones Garmin navigation. It will send upcoming turns to my BT headset so I don't have to worry about hearing it from my phone's speaker over any music. The Bose does not block out all sound so you can easily have a conversation with the person next to you while wearing it.

Ok...long winded I know so I will wrap things up.

This BT headset is expensive compared to others, but well worth it IMHO. Is it perfect? No. Is it the closest I found for fit, volume, clarity out and in etc? Absolutely. Will it be for you? No idea. LOL

** Side note. I am impatient so I ordered express shipping (actually ships from Bose when ordered through Amazon at the time of my purchase). It was listed as 1-3 days for this. Bose shipped it overnight priority which was great.
