Let me start by saying I owned the original ERA and I loved it, it was the smallest BT headset at the time and it is still one of the smallest, but the new ERA 2 takes it to another level.
The headset comes in a really fancy box with 4 eargells, charging cable and a manual.
It has only 1 button and an on and off switch which is good or bad depending who you ask, I however love it.
To pair the device hold the talk button down while turning on ERA. Keep holding the talk button until the LED light on the headset flashes white and red. When the LED light flashes red and white, the device is in pairing mode and you can release the talk button.
To control volume you press and hold the button while in a call, and the volume cycles up and down. Press the button once to hear how much battery time you have or during a call to hang up. Hold the button down to activate Siri.
The head set is very comfortable in your ear and doesn’t fall out.
The batterylife is around 4hr during use which is on the low side for most but the small size and audio quality make up for it. I have owned this headset for 8 months now and love it.
