A helmet for sports.

I rather appreciated that helmet, which currently is less than 20.
Overall I like the sound and is in any case much better than the "Ace KitSound Earphones" in the same box and an equivalent price. It seems to me by comparing it with others, that the bass is slightly amplified (which is not necessarily a well, unless you're a fan). Details of his correct.
I compared it with KitSound KSRIBBK (which I prefer even if I struggled to decide between them, which seemed more focused on acute but more detaillé) and a Sony MDR-ED21LP unfortunately we do longer and in my opinion surpasses (but his old caps hurt the ears).

This helmet is not a headphone like no other:
- It is supposed to be resistant to sweat or rain droplets (etanche I doubt), and is designed to accompany you during your exercise
- For it is secure when you exercise, it has a fastening system by ear a little special.
For now, I find this system really well: it does not hurt, and it blocks the headphones very well: absolutely no drop or slip out of the ears headphones, even supported the movements of the head.
Moreover, even without talking about sport, it seems that this binding avoids the noises that some helmets are in motion.

So for twenty Euros, we have a headset with its correct and very good resistance to ear at all times, even sporty, and is supposed to withstand rain and sweat.
It seems for now the goal is rather well done.

To note:
Right connection.
Durability: to assess but no obvious defect.
There is no left or right headphones, they are interchangeable.
A clip allows you to hang up on a wire clothes (certainly to limit their movements during sports)
