Looks much larger (and I suppose heavier) than the AirPods. No matter what they say about the design I doubt it can be confortable and fit securely for everyone.
Also the experience of charging/pairing/connecting them in the Apple ecosystem won't be as seamless.
Only possible upside I see is that given the design isolation should be quite better and that the *might* produce better sound (this remains to be seen - or heard - but the AirPods are quite basic in the sound quality department and shouldn't be difficult to beat).
Actually to be honest .... Bragi, Jabra (Sport Elite's) and about 5 other smaller 3rd party truely-wireless headset earpiece makers are following the same charging/case design principle. Lightning Cable vs MicroUSB is the same as before.
The sound quality we really know nothing about, along with active noise cancelling or spacial sound pass-thru if that'll come along on shipping day of the AirPods. Nobody but Apple employees involved.
I'm more concerned if Apple will allow someone to buy just 1 replacement earpiece that in the case and via iOS/macOS will repair into a new paired sync with the non-lost half of the original pair.
We need foam accessories to colour or flag the AirPods and loops to give them a more rounded universal or custom fit.
Then Next year Apple will release these in Jet Black, Black, Space Grey, Silver, Rose Gold, and in Gold to match our iPhones, iPads, MacBooks and of course our AppleWatches so that we can ALL co-ordinate.
PS: I watched the pilot show of NetFlix's Original Series Broken Mirror (which is exactly like The Twillight Zone in many ways). I'm afraid Apple is getting so such a future with FB, Insta-whatever, and such as ratings tied to ApplePay will be the end all and be all of the kids sandbox where fake personalities and populatories win.
But again, trade offs. With the AirPods it is unfortunate that Apple requires Siri to do so much. And of course the whole fit issue. I just hope the Bragi's are a good product.
