Query: nice, but..

after having for years the SONY pro HD series I purchased these for my home studio- they are compact, the fit nicely on my big head- the bass response was at first a concern, but I think that you just need to get used to them- the really only concern I have is the durability of them- they are tight- they have a spring loaded frame around them and they snap very quickly when you remove them together- I do not like that- it makes me wonder "when are these gonna break?"- besides that they are fine- watch the snapping though!
