I have bought the Airpots, and I really like them. Yes, they are extremely pricy, but in my opinion, worth it, depending on what you wanna use them for.
If you are the kind of person who easily drop things, then do not buy them. You'll loose them in no time.
You need to control the volume and music playback using Siri, or do that directly from the phone. I'm not the kind of person who wanna talk to my equipments, especially not out in the public, so I use my phone for that. For me, this is not a big deal, but a lot of people hate it, and I do understand why.
I like the battery life and the awesome charging and caring case. The battery last for like two weeks for me, depending on how much I use them. They easily fit in all kinds of pockets, not like many other headsets I've seen which is also great for me.
Yes, you can easily hear things around you, just like the Tatainium headset, I have even walked out in the trafic and used my GPS with my Airpots without any issues.
All headsets have their good and bad things. No headset is perfect. If you don't like the Airpots, then just don't get them. It's very individuel what fits your needs. I could say a lot of bad things about the Titanium headset as well.
