Hello, I can see that I am the first one to put my review, well first of all I like this Jabra design of the ear gel and the rest of the headset is behind the ear.The new good thing about this new BT110 is simply that it works with AAA battery, this abolishes the defect of shortening of the life of the previous built in rechargeable batteries,imagine that you travel without a charger, when the battery is empty you just go and get anoter one from anywhere.the second good thing is the automatic power off after each call that made my first battery lasted for 12 days. Well I think i tried it for around 1.5 month now with my I-mate PDA2k and it worked perfectly.Ihope this help
