Not bad, yes, but that's all

In all cases: a nice product in hand, not too heavy, soft, comfortable, elegant and rather qualitative. The settings fall under the hands, it is well done. Autonomy bluetooth, a 20aine hours, has no equivalent on the market. To emphasize that it is well insulated, you do not disturb your neighbors in transport with your music ... not bad qualities in short.

Listening, I said that I spent a lot of time to hesitate with three other wired models. I finally chose to pay less, and have a robust, foldable, less flashy in transportation, and wireless ... so of course the Sony.

The other three models are the Sennheiser Momentum, the Bower and Wilkins p7 (foldable) and little French goes up in the name ... Nordic (Aëdle vk1). I also gave a good listen to the Parrot Zik (see end of review).

Let me be clear and simple: three wired headsets above are better than Sony.
The class above all. I would say that if you search neutrality, we will choose the Sennheiser. Clear, musical without weakness. But not charmer on the bass register. At least these are they pure and precise. The Sennheiser is however not comfortable and not practical. If it is the clarity of the midrange with a sound rather sweet that is sought, then the P7 is really enchanting. In a truly refined listening (I hesitated to take it). The Aedle helmet is really nice too, with a dose too strong low for my taste, but is a specific helmet, with the holding short again of very good level. But watch out for the latter is fragile, luxurious and not folding ...

And Sony?
- Well, if the other 3 are between 16 and 18/20, it approaches the 15/20 wired. It is not very powerful, it's not super musical, but it's clean and homogeneous. I appreciate the good dynamic range, precise stamps, chiseled highs and not at all aggressive, and insulation against the outside (fortunately also for its low power, which must result from an average )
- In blue tooth, let's be clear: it is really great .... for the blue tooth. It is even stunning. To emphasize that there by cons no power problem, there is juice! But where were punchy bass wired, it hums a little BT. where the amplitude of the sound and dynamics could seduce wired, it becomes more compact BT. In short, it is sometimes not far from a form of sound mush and my ears tired quickly if the volume is too loud. Blame it on two things: the Bluetooth signal and integrated amplification.
- Bluetooth signal (3.0) is sometimes a little chopped, "eat" little bits of pieces, including the beginning of tracks. Nothing insurmountable though. It is very well overall.
- Integrated amp is not bad at all. He hardly generates noise. But it can not compete with the original signal. This lack of dynamics and sound is less natural.

I would give here between 12 and 13/20, that is to say blue tooth. (15/20 wired)
Average: 14/20

In the balance sheet, far from being a bad helmet. It is especially convenient and not too expensive. I would recommend just to avoid comparing it with a real good wired!

To note:
- I also spent a few hours listening to the Parrot Zik. For me it is a little deaf in the midrange and treble. But may be less messy than the Sony in severe? I preferred the Sony overall.
- All this does not come at the ankle of my "old" Beyerdynamic DT990 good but it is a large residential and wired headset, one ...
