Noise canceling anecdotal, painful bluetooth, very limited battery

To sum up:

The pros:
It is well built, is robust enough (compared to the Bose QC15), excellent finishes, accessories provided comprehensive, no complaints at this level.

The -:
- The noise canceling is really anecdotal. When put on the way, hard to be surprised by it, you really turn it on, turn it off, turn it on, turn it off, to make a difference. The headset looks a little better naturally isolate noise that the Bose QC 15 (insulation and more efficient foam?), But the noise canceling "active" is useless limit.

- Limited maximum volume. Where the Bose QC 15 can saturate the bass level when I put strong, the MM 550 X is not likely to have this problem as the volume often seems feeble bluetooth. It is less in filiaire but buy these headphones for use in filiaire no sense (and even if you have to like lugging the wire with you and never forget ...)

- Anemic Battery: 8h announced, this may be true. But as there is no charge indicator (green LED just indicating that it has finished loading when it is supported), we quickly found to have a helmet that emits painful beep beep every 15s for that it is unloaded. I tested four days and found myself empty twice, without the audio cable with me to continue to use it. This is certainly the lot of most bluetooth headsets have a range like this, but have no indicator, it is painful. Impossible to know if we will take a ride leaving in the morning ... On the other hand the micro USB connection is particularly poorly integrated, always fiddling before you get to connect headphones (even by removing the battery and using the supplied cable), the grip of the battery system and the small plastic cover almost leaving no room for an outlet.

-Free Bluetooth lousy? Here I will not be too critical because I do not know if it comes from the helmet in the background ... The assocaition goes perfectly with my HTC One (one of the few that manages the Bluetooth phone APTX compatible with this headset, so priori any glue), but when using I often find myself with popping reminding all the time we are in and that the Bluetooth connection is not perfect. Hard to say if it's related to the headset, my phone or bluetooth in general, but I have absolutely never had this problem with my car phone bluetooth listening to music, so amazing.

-Interface Painful enough: where the Bose QC 15 has a single on / off button, turn on and off the MM 550 X goes through 4s trustest. This may sound trivial, but it quickly becomes painful to have to rely 4s to turn on or off his helmet. The best is when the headset is lagging in, and we do not know if it is on (so we want to turn it off), in this case, hop, 4s is pressed to turn it off, and then, m **** ah no, it was already extinguishes, hop, 4s to re-extinguish.
I stopped to serve me on the helmet controls (pause / forward / backward) because the lag 2s it there to control Spotify (not to mention the fact that it works two out of three, the worst frustrations) is very painful.

I turn on my Bose QC15, it's a shame because I really wanted a new helmet, but then clearly the MM 550 X is not at the top. The Bose QC 15 as its default (though not top finish for the price mainly), but is much more effective for the active noise canceling and less frustrating to use.
