I have a set of these, my boss and Scrapegoat have them as well
The sound quality is great, plus they stay connected to my iPhone and don't get all jacked up like my old BT headphones. Phonecalls are reliable and have good sound on both ends.
Scrapegoat ordered a Scala Rider Q2 when we got back, and while it's a cool unit, it doesn't want to play music over BT from his iPhone or any adapter I have. Works fine for calls though.
