You are advised to fully charge the before first use. I left a good hour to a USB port on the computer before the load is complete. We guess it through a discreet red LED which cuts once charged. Then you must hold down and hold the power button until the button blinks alternately red and blue to be able to sail. The smartphone detects as M04. We can then put his helmet on and fully control his music from the headphones. The play / pause button, volume + or - next or previous track are present. Best of all, you can even take calls using the on / off button as the headset has a microphone. When you hang up by pressing again on / off, music immediately picks up where it left off. In my test, the quality was good, with a little support, however.
His side, I am fully satisfied with the quality of the helmet. I listened to several very different style of albums, including some well seek low and I was quite convinced. At maximum volume, you can not hear any crackling, quality is at the rendezvous. The helmet insulates well enough and you have to remove the headphones when someone speaks to us, even at low volume.
Aesthetically, the headset is quite successful with her look all black. The materials are adjusted and foams well hold on the ears. They can rotate up and down and sideways. The helmet fits very well with a good stretch and well protected by foam headband. With its 210 grams on the scale, it is forgotten easily. In terms of ergonomics, an adjustment period is necessary because we do not intuitively located buttons (they are quite small and placed one beside the other, I would have preferred a knob for sound). When you arrive at its maximum or its minimum, a little noise we reported it but it is quite annoying. This allows in contrast to perfectly adjust the desired sound level; one can really put such a low sound in a quiet environment in the evening.
In summary, we take a great Bluetooth headset with an excellent quality-price ratio. It has become an indispensable companion of my smartphone.
Pros: - Design - Sound Quality - Built-in Microphone
