Awful. This is the worst version of my favorite ear buds. I'm so disappointed! Left ear bud intermittently fails and has no charge nor the ability to charge, so frustrating.

Excellent sound quality, the noise cancellation is wonderful and the addition of the Aware mode is an awesome feature for not isolating yourself from your surroundings. The only disappointment is that they seem under powered when compared to others in this price range.
