I bought a pair of the Rockaway's a few days ago. They're spectacular. I managed to get 4 hours out of the battery, which is great, as I only need about an hour and a half on the train commute. I was looking at the Plantronics Backbeat GO, but they're not available in Canada until June. They lost my business doing that. Go with the Rockaways. The only issues I have with them is when you first turn them on, the volume is preset to be pretty low. You have to crank them up every time. Also to turn them off, you have to hold the button for about 6 seconds. Not much of a complaint. They're pretty good.
