First, I do not practice running but the freestyle slalom skating and freestyle skiing.
So I have no shocks when I practice my sport like stride joggers. Keep this in mind when reading this review.
Let's start with the sound.
It is rich with clear and very deep bass treble for non intra helmet is surprising and significant.
The helmet, being open type, allows you to hear the sounds of the environment around you (which is the purpose of the helmet) and therefore when you take speed (rollerblading, cycling or even running ) you'll also hear the wind noise in the ears, that makes sense given the config of the helmet. If you do not want this, orient yourself to a rather ear headphones.
For the slalom, as the moving speed is almost zero, no problem. If I do freeriding, I hear a little wind.
That said, it is absolutely not annoying.
The cable and the control on it.
I was hesitant in buying this helmet that the control on the wire is troublesome given the number of negative comments about it. When unpacking the product, I laughed ... so its size is small and light weight.
Specifically, we do not feel absolutely, is very easy to access and commands to run (press 2x for the next song, 3x for the previous ...) are very easy to remember. This works very well with my iPods (nano and classic). However, I have not tested the telephony features, with no iphone.
The cable, he is very strong and the small clip comes with keeps it on some of your clothing. In slalom during quick rotations entraiant action of centrifugal force on your clothing, the cable does not move absolutely. Happiness.
Clothes.
If the headset can be worn under a helmet, a neck garment amount (polar style) will hinder you.
Tip: bend the neck 2, otherwise when you will report the head, the helmet will abut on the collar. This fact, more than discomfort.
Finally, the glasses.
I wear glasses permanently correction. My legs are medium thick (3-4 mm).
The helmet, bypassing the ear and passing between the ear and skull, lightly touches my branches.
This is absolutely not a problem so the pressure is low. The sound is in no way altered by grinding noises as the helmet does not move absolutely.
I can also remove and replace my glasses to wipe my sweat. Again, the glasses are recovering smoothly even if the headset is still in place.
Summary.
An excellent product meets its specifications and which pleasantly surprised me.
It has a very good sound, is extremely lightweight, well designed, fits comfortably in place and adapts well to wearing glasses.
I would buy without hesitation.
