After about 3 weeks of use, I think I can fairly make a first overall return:
+ Lightweight and comfortable, we quickly forget and we do not see the time passing
+ Bluetooth (very nice), my smartphone is safe in an inside pocket. The buttons allow me to change tracks, pause / play or adjust the sound without touching the phone. Tested with iPhone 5S and Galaxy Note 3, without any worry. Warning: a pairing of both, which makes sense.
+ Audio quality beyond what I expected for the price, even if he does not expect either to a Momentum or Spirit One, which is logical. Aficionados of neutrality, you are mistaken ad (and price!).
+ Beefy bass (it pulsates on infrared!), The atria vibrate at full volume, it's pretty impressive
+ Good insulation from outside noise, even without sound. The atria are wide enough to make a closed helmet.
+ Sufficient power (+ 6 hours without recharging need to think about it). Moreover, the refill is rapid.
+ Refill micro-USB / USB, the computer sound is also transmitted to the headset at the USB connection.
+ Ability to use a jack cable to continue listening for an empty battery or non-Bluetooth enabled device
+ Design simple and elegant. No fuss, no bling. Perceived quality very honest, it does not "cheap".
+ Her very affordable price: 39,95 when my purchase
- Holds a little hot (the atria are soft and comfortable, but can heat a little, depending on your sensitivity)
- Purists will say that there is perhaps a too-oriented bass emphasis, which is true. It is not as pronounced as on a Beats by Dre, but not as balanced a Spirit One (I've owned before, hence the multiple references).
- The microphone is a small hole in one of the atria. On appeal, I know you hear me wrong, because in public, I talk to rather low voice not to disturb others. A collapsible / retractable leg to the microphone would surely have fixed the problem, there, I sometimes get my phone to talk into the phone's microphone ... which loses its usefulness. But this use is not important for me. However, for people who telephone a lot, I might advise against this model.
- RAS for the rest.
For urban use, I recommend it.
[EDIT of 07.05.2014] No reliability concern after more than 5 months (still happy). My partner often monopolized, which led me to buy the same model for her in a different color. We are both to be satisfied.
[EDIT of 03.16.2015] Always so good, this helmet spread in the family. We now have three. However, with use, I found him another flaw: the battery end warning occurs at a level far too low battery, so I'm surprised every time, and at the first alarm, I understand I finish my ride without a helmet. Should the threshold be raised to allow time to finish a journey of about an hour (this seems reasonable) and then put the charging.
