These are hard to review - the sound quality is excellent, and the physical design is amazing - these stay on through even my toughest runs and are extremely comfortable. The deal breaker for me: even paired with my phone in my arm-band, less than a foot away, there are continual skips and drops in connection, resulting an a lousy experience. It seems to correlate with 1. outdoor running in an urban environment and 2. sudden head-turns (a necessity when running on busy streets). I can use them easily in gym, but not out for a run. These could be great, but the inconsistency in audio isn't acceptable.
