aarong,

HBH-30 is not newer. It's sort like the 30 is consumer and 300 is buisiness.

I had trouble pairing mine too. Make sure you hold both +/- in to get it in pairing mode. Try different distances and environments (away from compute for example).

Sometimes had to try several times, clicking back and next, toggle bluetooth etc. Once paired it was fine. I was suprised other folks never had problems pairing.
