Although for limited use

I bought this helmet mainly for sports indoors (outside I prefer my intra who do not move a muscle), where I can put my phone in a corner or tablet with a series on while bluetooth.
The headset works well. Do not hesitate to keep pressing the button (until the appearance of a flashing blue / red) to pair your devices.

Good afternoon, do not get carried away. The sound is not bad, but it's still a headset to "troubleshoot". If you are looking for a good headset for listening to music, not already looking for a Bluetooth headset you never have a good sound reproduction (bluetooth compression forces).
Here, the bass is too present, and mediums withdrawals even after adjusting the equalizer as it should. But ... BUT ... Is that why you buy this kind of product?
If you're like me, you are looking for some things to do sport while having a clear head, or even in transit in a pinch, this helmet will entirely the case. Although the sound reproduction is not at the top, he manages pretty, and the insulation is pretty good for this kind of attachment (even if in the end, I prefer the more traditional headphones with a headband). After a few minutes, the headset is even forget!
