more seriously I have recently and no complaints, very good sound, excellent soundproofing, discrete, can be an unpleasant can after 2 or 3 hours of use ... I want to say normal for intra. flat cord works really well in terms of the fact prevent the nodes for strength it remains for me to wait to see if they are as resistant as what I hoped by purchasing them.
In short very good product I recommend especially vis a vis its price
