Moved to Bluetooth Connection.
Here is my breakdown of the best I have used:
Jabra BT530 :
Noise Reduction: 7/10 - Good in moderate noise.
Fit/Comfort: 9/10 - Ear gels and removable loop, quite comfortable after 2 hours of use
Local Audio: 8/10 - loud and crisp audio, no echo or static
Recipient Audio: 7/10 - minimal echo, digitized effect
Look: 9/10 - discreet, flat black
Battery: 8/10 - lasts through 2 works days of moderate use
Misc: I absolutely love the dedicated on/off switch located on the underside
BlueAnt V1 :
Noise Reduction: 6/10 - Average overall noise reduction, "Voice Isolation" causes digitized sound and echo
Fit/Comfort: 9/10 - Ear gels offer good comfort, and the sliding loop creates a custom fit.
Local Audio: 9/10 - as good as I have heard
Recipient Audio: 8/10 - very good with limited background noise
Look: 7/10 - slightly bulky, and the loop looks industrial
Battery: 6/10 - requires a charge after each day of use
Misc: the in ear voice prompts are a nice feature, and the buttons are easy to use
Jawbone 2 :
Noise Reduction: 9/10 - Excellent reduction in the noisiest of conditions. Has a tinny effect when activated.
Fit/Comfort: 7/10 - my ear was sore after a few hours, constant contact with my face is a nuisance
Local Audio: 7/10 - occasional echo
Recipient Audio: 7/10 - echo, and muffled audio
Look: 9/10 - hidden buttons and LED, pattern is nice as well, multiple colors available
Battery: 6/10 - lasts about a day with moderate use. Noise cancellation appears to drain the battery quickly.
Misc: nice looking device, awesome while driving in the car and delivering clear audio, easy to bump the exterior and end calls by accident
Plantronics Discovery 925 :
Noise Reduction: 8/10 - Very Good in moderate noise.
Fit/Comfort: 8/10 - no loop, well designed ear gel, secure fit
Local Audio: 9/10 - as good as on the handset
Recipient Audio: 9/10 - recipients thought the audio was improved from the handset audio
Look: 9/10 - basic chrome, and simplistic design, many color options
Battery: 10/10 - comes with a case that has a small battery inside to charge while on the go, this extends the battery life
Misc: The included case is something all BT devices should come with. The fact that it also adds some battery life is a pure bonus
