Can you share how this unit is working with the 4s? I was a long time Blackberry user and recently converted to the iPhone 4s. I used a Voyager pro for a long time with my BB and it worked perfect. I ran it through the laundry one day and even though it still worked...the speaker was damaged and the sound was not as good. So I bought the Plantronics 975 and it was flawless on my BB. People could not tell I was on a headset and audio was great both ways. Now with the IPhone it is horrible! People tell me I sound like I am in a can, it cuts out, my voice goes digital, etc. I can hear them fine, but audio out is terrible. I am in sales so in the car many hours a day and on the phone. I don't like people holding a phone to their head and driving...been cut off too many times! So I always use a headset. But I need one that works perfectly! I am reading that no Bluetooth works well with the iPhone 4s due to issues with the phone. Well...first and foremost I need my phone to be a PHONE and work properly. Nothing else it can do really matters. After all, I have my iPad for everything else! I may end up giving my iPhone to my son and going back to a Blackberry Bold Touch...at least the phone and Bluetooth both work extremely well for their core purpose of being a phone.
So...how does the Pro HD work w you iPhone? Might be what saves my iPhone.
Thank you!
