Received this morning, on time. It is the first helmet of this type that I purchase. I have it on good ears for two hours. It is lightweight, comfortable. Certainly, it's a little out low, for those that gene. The relationship between quality and price makes this headset a must. The sound is very good. I can hear the details completely masked with basic headphones mp3 player. There I am not at all disappointed with my investment. I highly recommend for those who want a headset at a reasonable price, but a light helmet, worn long and sound good bonus. The only flaw, if it is one: it does not fold. Let us add that the wire is thin, which weakens the helmet (the underlined default Internet), especially if (like me), the goal is to be able to use in transportation. What to see in use. All the same, I put 5 stars because, after I learned about the different hats, I think it Sennheiser HD 419 Headphones HiFi (2 year warranty) is part of the top of the low end.
