I use this headphone recently and am very pleased, indeed, I'm bassist, I play with and, finding it merely makes excellent bass, with little spill over into other frequencies, plus it is so closed that completely isolates ambient noise (live great), unfortunately the jack connection is very long and very thin, so easy to break, and it is also unfortunate that the jack is not directly format, 6.35 mm but that we should put an adapter (provided).
In conclusion, this headphone is a very good headphone that has all I would recommend for its superb quality price ratio
