Very correct headset

I took advantage of Cybermonday and a Flash offers to try to replace my old Philips SHB-9001, which I love but little by little from leather and plastic poles broke in places.
Test after 2 hours of use (3 trips in transport).

Strengths:
-Helmet very light, we almost forget once on the head
-coussinets very soft, good contact. Only question, how will they grow old?
-good sound (no compensation option as the other, but it seems pretty balanced)
Quickly tested several genres (pop, rock, classical, acoustic guitar or various BO, no discomfort. I do not listen or rap or techno thump thump, I can not speak for these genres)
-volume satisfactory (no need to push it fully, it may well be immersed in his music without disturbing a neighboring office)
-design sober a more angular hair (although I would have preferred to have only the brand, without the words "Bluetooth stereo headset"
-cable micro-USB, mini more common than now, with smartphones
-Key to play / pause / call / pairing smaller and easy to find blind, the SHB9001 we quickly tend to inadvertently initiate a call (entire area served loreillette button)

Negative point:
-no jack in case of flat battery (I knew with the description, but it's convenient if you forget the usb cable)
-more sensitive to wind (meaning a "frouch" while with the other, nothing, tested the same day)
-no buttons previous / next, only the keys that double as fast forward. No biggie either.
-The sound of its control keys precisely, with jurisdiction makes a nice 'dong', and can disrupt according to music. At worst we play with the volume control directly on the smartphone.

Other remarks;
- No foam / leather on the headband, but it seems to be stiff at once adjusted, we do not feel the contact on the skull. Well it should not be an extravagant hairstyle;)
- Headphones provided "naked", with only its cable, where its predecessor had with a cover and the jack cable (but useless here)
- Easy pairing with an iPhone 4S, nothing special. All Bluetooth equipped device will do the same.
- Microphone for calls not yet sufficiently tested, usually one is fairly well understood by the caller.

Autonomy announced 9am, against 15 to 18h for my other headphones, to see after several days. But obviously as it is lighter, autonomy will be reduced.

In the end I think it will not replace my 100% SHB 9001 (which will eventually crack completely one day), but the majority of functions and ergonomics are there. 50 For it is a bit expensive, but promo normally 42 or even 29 in flash offers is very correct.
I put 3/5 a star less for smaller defects observed in use, and another less because I lose some functions or facilities as compared to my previous headset.
