Meet the ERA by JawBone: a lightweight, small, and comfortable headset for iPhone and Android devices. It is designed that uses the natural contour of the ear to create a secure fit. It offers 4 hours of talk time. The charging case more than doubles that. The ERA uses military-grade NoiseAssassin that eliminates background noise, so the other side can hear you wherever you are. The companion app lets you customize your experience and locate your headset. Want one? Sets you back under $130.
