Went to the Apple store this morning to try out a pair. The Apple Genius paired up a set to my iphone. The process was easy. Soon I was hearing really great sound quality. I honestly didn't expect such dynamic range as my older wireless BT ear system is extremely tinny. As with most things Apple the operation and quality is very high. The cool think is when you want to do something like turn up or down the volume, select a different piece of music, you use Siri and just ask. Turn them on by inserting them in your ears. Turn off by removing them. I'm impressed and it looks like they will be on my next Apple order. Now for the bad part- As usual I always ask whet seems to me to be a simple question and it stumps the Apple Geniuses. Since the Air Buds shut off when you remove one from your ear, can they be used with only one, say for mono sound, like an audio book? 3 of them didn't know the answer. Called the super Genius from the back and it took awhile before he understood my question. He didn't know either. So I'll need to ask Siri. During the demo I could not figure out how to use just one at a time.
