Freedom bluetooth ...

Getting easy road, synchronization with multiple devices without the slightest worry.
These headphones come with:
2 sets of stabilizers: to strengthen a perfect fit in your ears.
3 sets of ear caps to s' adapt perfectly to the ear canal.
1 small charging cable: about 7 cm! a little courtyard on a traditional computer without remote hub.

NFC also works well.

Packaging announces the presence of low I Ralais finding that they were non-existent in reality the problem was me: headphones were poorly positioned in my ears.

So I took time to test each tip with each of the stabilizers. Result: I did not need it and that each has a different ear tip ....

Anyway now I am enchanted by the sound from the earphones.
The volume control only controls the headphone volume, not the volume of my phone eg unlike wired.

At the office, they will replace my MR Beat by giving me more freedom.
I can even leave my phone near the window sensor for the mobile phone network and get from my office: The range is given for 10 million I have only tested 8.
