Excellent helmet, attention to your audio source!

Some important points:
- Can be awkward for eyeglass wearers, the strong greenhouse headphones on and the helix flag (outer edge of the ear) can be compressed against your branches, helmet adjustment and limb straightening and is nickel.

- Your sound source must be of good quality, it's limit boundary with a mobile phone (Nexus 4), the helmet really gives his potential combined with a good source. To give you an idea, the sound is at about the same volume when it is at third on my Macbook Pro and fully up to my phone ... and quality suffers, a laptop has more wrong with emphasizing the dynamic. This does not stop listening with his phone in nomadic course :)
Quality also requires your files and your digital source, forget all your mp3 320kbps below, choose the lossless (but it is not always easy), you will see, you will become very demanding! An internet radio or a poorly mixed live will be difficult to apprehend ...

- After a long listening or if you ride too sound to enjoy, eardrums let you know that it was a taste, it can be a gene or a light thud for a few seconds when you stop the clear sound (insulation plays a lot). Keep your ears, take breaks!

Finally, the headset looks very solid, and in any case the cable let go long before the speakers, a good point because it is replaceable!
