I occasionally have dropouts, but it's happening much less frequently than before the last few updates. And to be honest, in always wearing a smartwatch that's connected to Bluetooth, so I think that could be contributing to it. But overall, great ear buds.
The only think I wish they had was aptx. I had to connect an old LG headset into my Chromecast with Google TV to get audio and video to properly sync. Seriously? C'mon, Google....
The buds sync up fine on my phone, though. No lag there.
