- as mikew above has said, you have to put the earphones in pairing mode

- the instructions indicate that this happens automatically when you first power on the earphones so it may not work if you are tying to connect to a second device or something like that, which was what went wrong for me

- I found that by pressing the two volume buttons simultaneously, the earphones went into pairing mode (though i'm not sure if it just factory reset the earphones or manually started pairing mode)

Plantronics Backbeat Go 2 Pairing Mode

Plantronics claims the case can add an additional 10 hours to the BackBeat Go 2's 4.5 hours of listening or 5 hours of talk time, making the extra $20 for the carrying case a very good deal. Together, the headset and case package retails for the same as the original BackBeat Go did at.

- you will know that it is in pairing mode because the voice says 'pairing' and there is a light on the right earphone that flashes red/blue intermittently
