I've narrowed my choices down to 3. They are: 1.) Altec Lansing/Plantronics Bacbeat 906/903 (4/5 stars - CNET) 2.) Motorola S9-HD (3.5/5 stars - CNET) 3.) Jaybird Freedom 200 (3.5/5 stars - CNET) I will be buying one of the following to use with an iPhone 3GS. Basically, I want a stereo bluetooth headset with great sound quality with good bass (obviously). I will proably use these to workout in the summer, so I assume sweat will be an issue. I'm less concerned about call quality, but want to know how good these 3 headsets fare in that department as well. Price is not an issue for me, since they're all around ~$100. Oh, and also, I want easy to use music controls on the earpieces. Also, I have a slightly larger head, so is fit an issue with any of the 3? Which of the 3 has the best? Which headset, OVERALL, is the best for performance/quality??? P.S. With regard to the S9-HD, does the iPhone support AVRCP yet for the track switching key on the earpiece? Thanks Also, late additions to my buying choices are the Plantronics Voyager 855 & the Sony Ericsson HBH-I800 (However I heard you can't control the volume at all with my iPhone??? Has this been fixed?) So which out of the 5 is the best????
