They are good for home use,although after several months of use I came to the conclusion that they are overpriced and you can get something better with less money.
But if you like the slightly colored sound signature which is better to listen at moderate volumes,and your ears don't stick out much so you won't have comfort problems,then it's a quite good choise.But honestly,for me,my shure srh840 is an overall better headphone,better value,a bit better sound quality,better isolation.At least that's my personal opinion.
Sound quality wise I also think that at the same price,k550 is better overall. And for higher volume listening I also find my krk kns 6400 to have better balance/more natural sound at half the price.And to be really honest,I find my koss portapro to be more balanced too,although a bit unrefined sounding and not with so good imaging as the sony's...
I don't know why,lately I don't really appreciate this headphone that much...I think it's quite overated here.For me it's not 200 euro good...maybe at 130-140 euro max it would be fine for what you get.At least this is my opinion.
But again,if you like slightly colored sound signature,and low to moderate volume listening at quiet places,and your ears don't stick out much,then you'll probably like it as it's a decent soundning headphone with not bad overall balance,and nice imaging.
