Very good helmet
As soon as I unpacked it, I put it through its paces for 12 km in the rainforest, with a fair amount of rain, and I was completely satisfied. The fact that you can hear your surroundings clearly while enjoying your music is really appreciable and even disconcerting at first.
Lightweight, comfortable, very good sound, even if there's a slight lack of bass (easy to correct using the settings on my phone). I chose these headphones so that I could clean them with clean water after each training session without worrying. We'll see later if I use the internal drive to store MP3s (only useful if I'm swimming or away from the phone).
So I can highly recommend it.
