I have a love/hate relationship with my AirPods. On ios11 I've had a lot of issues, so it might just be that (didn't have them before the beta). Here are my issues:
1. With 1 in my ear and 1 out of my ear, but not in the case, music still seems to stream to both AirPods. This messes with the stereo output. I have to physically put the unused one back in the case to get stereo out of one side. With 'auto ear detection' I don't see why it operates this way.
2. Occasionally, pulling the 1 AirPod out of my ear doesn't actually stop the audio, so listening to an audiobook gets frustrating because it keeps playing and it's hard to figure out where I actually left off.
3. I thought auto-pairing would be a bit nicer. Switching between watch/phone/ipad should be more seamless. While it auto-pairs to the iPhone correctly about 95% of the time, if I pair manually to my iPad, and later try to pair to the phone, I always have trouble. Just thought W1 would be cleaner than it is.
4. Double-tap to play/pause only works intermittently. Seems the app being used behaves differently. Some apps will play with a double-tap, but not pause, others pause but won't play. I think Apple Music is the only one that reliable plays and pauses with double-tap.
5. Wish you could slide your finger up and down the side to raise or lower volume, like a touch panel. Having an Apple Watch makes control with Now Playing MUCH better. I can't imagine liking the AirPods as much without an Apple Watch.
