Finally ... 201

- Fast delivery, received with 1 day in advance.
- First and events have yet nothing to complain (running). The Bluetooth connection is excellent and does not cut (iPhone on left wrist) unlike the competition.
The helmet is forgotten but beware, the atria may Intra can start to worry because the plastic is quite rigid and create a small little discomfort (slight pain). However, after an hour of racing no discomfort.
It will take me several outputs to me really realizing it.
For now, and despite a somewhat high price I can only recommend the product (including micro-program can be updated via the application of the manufacturer).
I will return post another notice a few runs and muscu sessions.

---- Update ----

After a month of use earphones I am delighted.
Except once, a very strong during a sizzling spark that disappeared in the clutching and on, I remain fully satisfied with this product.

The Bluetooth to an amazing extent.
The sound quality is quite sufficient for its use.
Autonomy is good about 4 to 5 hours (depends on the user and usage)
The semi-rigid cable which prevents sticking to come in the neck when you sweat, preventing a voltage / draw on the atria, turning his head (bp I met with the Jabra Sport)

If we had to find a fault I would say the comfort of the atria, which can, after a while, become slightly painful, again it must depend on the users and their ears ...
