First time poster here, I have been looking around for a good pair headphones for listening to music specifically HipHop RnB and Lounge/Chillout stuff while blocking outside noise while I work. My choices were narrowed down to the AKG K550 and the Beyerdynamic Custom One Pro, the Beyerdynamic's are easier on the wallet but all the positive reviews on the headphones is what skewed my decision towards the Custom One Pro. Based on my music preferences, do you guys reckon these headphones would be a good choice? I also had a question regarding the replaceable headphone cable, would any cable be interchangeable or does it have to only be a Beyerdynamic cable & if so does anyone know where can I find the cables as I was looking to buy one in red. Also what amplifier would you guys recommend as I need something portable that I could take to work as well in order to properly break-in the headphones and use it to it's full capacity. I am interested in the AKG K550 as well but may think about that later, I see a lot of mixed reviews on it so I don't really know what to make of it, just wish the cable on it was replaceable.
Any help/feedback would be much appreciated.
