Sound:
The sound quality is really miserable (height to limp and basses I can hardly find any)
Sound isolation:
The sound isolation from the outside is so miserable that a TV peep Ender man my music from 5 feet away could still hear.
Processing:
The ear pads are made of a kind of artificial leather, these now crumbling off after some time, so everywhere flying around little black piece in the apartment and on the head.
Now I've got birthday AKG 518LE. These have now tasted anything at 50-60 euros, but have a definite added value. The outer screen is well done, full of the bass (but not overdone as in beats), otherwise very balanced. The processing is of course not made of cheap hard plastic.
So who are Philips NOT A RECOMMENDATION value, who claims otherwise simply have no idea of sound and workmanship.
