I can agree with the above post I have the 558 and have used the 598 and the only difference is the fact the 598 have a wider soundstage which can fixed by removing a bit of foam on the 558s
What are your thoughts on the b&w p5 series 2?
Does anyone have any experience with them?
Any other headphones you would recommend?
Will be used as my portable headphones as already have a pair of sennheiser hd598s for home use.
