Hi peeps !
I just bought this:

from this french site:
http://www.rueducommerce.fr/Telephon...duct_id=389168
and thought you guys might want to know that it is PRETTY DAMN GREAT, especially for bike riders like me !
It's almost "magical" in the way it works. The small end of the neck-band contains a vibration-sensitive mike that transforms your LARYNX vibrations into voice. No air-mike. And as a consequence, NO BACKGROUND NOISE, and no need to have it oriented towards your mouth !
And I'm *REALLY* amazed at how well it works.
Just made extensive testing, and the "pros" for the SNeck are:
- sound quality is *awesome* in work-type environments. My correspondants actually told me they were amazed at the clarity and absence of any noise on the line BEFORE I got the chance to tell them I used this. By far the BEST BT "headset" (which it ain't really) I ave ever had, and I've had top-notch stuff;
- sound quality is simply *flabbergasting* when riding a bike. At 60 mph (100 km/h), two of my correspondants didn't believe me when I told them I was riding, for they could hear only ME. In fact, it was the same as when at work, as stated above. At 90 mph (150 km/h), I was still completly understandable, there was just some "background hum". It is to note that the SNeck was NOT protected, and "full-face" in the wind.
The "cons" for the SNeck:
- build quality isn't near as good as sound quality. It doesn't feel cheap, but it doesn't feel like 150 € Nokia headsets, for instance. But it costs only 50 €, and they are VERY MUCH worth the price (at least in France
);
- for 45 mph (75 km/h) and higher speed bike use, "in-hear" silicon buds have to be added to the SNeck earphone, because if your correspondant hears you loud and clear, You won't hear HIM / HER at higher speeds. Using an in-ear silicon bud makes it very usable up until 120 mp (200 km/h) - I didn't test any faster; 
- not really a "con", but the answer button is a bit small for gloved-hands operations, and needs a little bit of training. A shame, they could have made it bigger pretty easily, as the BT head is not small itself;
- it's a bit strange-looking, but can be much more easily concealed than much smaller regular BT headsets.
All in all, one of the finest accessories I bought for my Athena, especially since I'm very often on my bike and can now have REALLY NORMAL conversations, without yelling or anything.
