Very good sound and made very low correct (I work in an acoustic service) can be easily connected with my SGS3, several tips neat design, but even with the smaller ones that fit well in my small ears (certainly) and small hoops above, given the weight and size of the headphones, they tend to slip qd moves. The large wire very wide and not very flexible or very light can be contributed to also ... but it has the advantage of being robust. I also found that the handling of all small buttons was not easy, and I did not large fingers! In summary a sturdy helmet that works fine but not convenient to use, for my ears to me! it would be nice if there was the possibility of adding horns that pass above the ear ... I'm trying to return against refund because not used.
