I use this everywhere now. I have a noisy suv (Mercedes G-Wagon) and people can't tell I'm even in the car. frankly I'm blown away. I never knew...I would have picked this thing up years ago. My only complaint, if there is one, is that if I have my Mercedes radio on, the headset won't connect.

as reported, quality of sound is brilliant, noise reduction very good...Had a glitch in that if you interrupt conversation by turning off bluetooth on mobile it sends an annoying buzz which only seems to resolve if you put headset on charger...

I only need to charge the battery once a week! I used this every day and find it super comfy. The thing I love most is that I can switch between my work phone and my personal cell phone without even touching a button.
