Got my BT-S2 from GearBest (IIRC), but the recommended seller would be fine too.
The bluetooth "quality" is crystal clear driver/passenger, , and my brother was on a bike more than half a mile ahead and we chatted clearly, , ,at 3/4 mile to a mile he began getting "scratchy". Remember though, ALL overcrossings, underpasses, big buildings, hills/mtns and stuff will reduce its range.
Taking phone calls, or making phone calls at 70+ on the freeway is a breeze, , and the other person won't be able to tell you're on the bike, , clear voice with minimal wind noise. My dentist's secretary called and almost fell off her chair when I told her to confirm my appointment and that I was doing 75+ on the freeway. She said I was crazy as hell to be on the bike at that speed, , , but dam the voice signal is clear as a bell.
