Comfort
Jabra is all about making sure that their products works w/ you and the Stealth is no different. They made sure to provide you w/ multiple ear gels in different sizes to ensure maximum comfort while using the Stealth. As well as ear hooks for additional support if you feel you need it. I was fine w/ just the ear gel setup and it quite comfy in my ear. FYI: it works in either ear (left or right) as well. I can leave it in all-day w/o any type of discomfort of sorts. I was even able to get a light jog in w/ it on as I forgot to take it off and it stayed in w/ no problems. So Jabra gets a thumbs up for comfort.
Battery Life
With it sporting a new smaller design than what you might be used to from Jabra, they have utilized a new microPower battery technology. This allows them to not cut corners like skimping on the battery life to sacrifice for its new look. The Stealth is quoted to have a battery life of 6 hours w/ consecutive talk time. For a Bluetooth earpiece, that's pretty good. Also, there's no charging cradle or special way to charge this. As small as this is, there is a micro-USB port on the inner side of the earpiece for you to just pop open the cover and charge it w/ ease.
Sound
Moving on to the audio side of things, the Stealth performs quite admirably. They have a feature on-board called Noise Blackout which is a cooler way of saying noise cancellation. It utilizes a combination of sound enhancement software + dual mics to better pick up your voice and drown out everything else. The end result: clear sound when talking on the Stealth. I could be driving w/ the windows down and still be heard w/o the listener having to compete w/ the wind in the background. This also works well when hearing GPS navigation directions and streaming audio as well. Works just as advertised.
