Offered as a gift to a person with some problems of purely physiological ears and supports no helmet enveloping .... except this one! Quality and comfort as she now discovers a deep pleasure she did not even suspect in his favorite songs. This massive model (and this is the least we can say) almost frightened by its size at first but becomes almost immaterial once placed on the head. Magic! Which spoil nothing, the quality of the reproduced sound, accurate bass and treble is very good, all for a very attractive price. Ear problems or not, I recommend.
