The tap controls on AirPods never seemed to work for me or anyone else i knew with them.
I think the big flaw with all airpod is no volume control, and you have to ask siri to increase or decrease volume, and isn't possible if you are somewhere that you must remain quiet. IMO that is essential. Some sort of capactive touch slide control IMO would make sense. The new squeeze control also doesn't look like a great solution from the reviews, especially as they have decreased the length of the storks. Kind of reminds me of that failed ipod shuffle that didn't have any buttons on it, and only had buttons on it, and I think it only lasted one generation before it they put the buttons back on.
