If in ear is what you're after Jaybird Bluebud X are highly recommended. They seemed good to me but had to return them as they simply didn't fit my ear.
I use the Plantronics Backbeat Go 2's, half the price and have been really good the year I've used them. Zero audio lag. Only 4 hours battery life though, negated somewhat by the charge case.
