Editor's Notes & Price Research
These feature a built-in lithium ion battery, microphone and one-touch call button. A microUSB charging cable is also included. -Corwin
Two colors (red and green)
Not a bad deal, currently sells for $20 at Amazon, I grabbed one since I needed a filler for the free shipping.
Also a great deal if you use coupons or shop your way points in conjunction with other items.
