On Kindle, audible, whispersynch for voice and Immersion reading

--help:
Amazon.de ebooks are working just fine, but you must purchase the audio from Audible.com

-vvv

I've been very interested in Kindle's (not anymore) new features: Immersion reading sounded like a perfect accent training help, and given my short commuting  time and various activities whispersynch for voice sounded like quite a nice feature to have. Finally I could switch between book and audio seemingly, finally a reason to justify at least in part the purchase of closed formats... but anyways.

Wait, hold your guns, the first problems are already on sight.
I live in Germany, and I have both an Amazon account and an Audible subscription bound to the german sites - or for what it matters - not .com
For new amazon's feature this usually equals to a wait time of about a year.
I've been waiting for an official announcement for quite a long time, but nothing ever came.
Preparing for the arrival of my new shiny gadget, I decided to have a look again.
Now those options are indeed appearing in the FAQs of both amazon.de and audible.de, but are all pointing to a .com page explaining the concept:

I therefore decided to give it a try:
I had already a copy of "The Universe versus Alex Woods" and according to amazon.com it is already whispersynch for voice ready.
I therefore bought the matching audiobook on audible.de (after checking if the audiobook was really the same - I can't do much, but at least appears to be same length and same edition as the .com one).
Unfortunately this is not going to work for now (it's according to their support, work in progress)
While you can purchase the ebook on amazon.de, only the audiobooks purchased on audible.com are going to give you access to both whispersynch for voice and Immersion reading.
Yes, you can actually buy from audible.com even without a CC or address bound to the land of the free.

If you are just interested in trying it out, have a look at the classics 
The ebook comes for free and the audio is slightly more than a dollar.

If you happen to like the experience, but are not into making another subscription, audible.com still offers gift cards.
