Well, that probably means i should look around once more, for portable headphones under 300$ ... thanks for your opinion.
If you could weight them, how heavy they really are? I also forgot to mention, that i'm looking for allaround headphones, i can take with me. That is what i do now with my ATH-M50's at least.
P.S. if those modified fostex are comfy enough, i can disregard the weight i think.
The ZMF (Fostex T50RP) is not really heavy for me, specs indicate 330g +/- the dampening materials they put inside so roughly 350g (don't quote me on that
So I need to correct my statement a bit, The T50RPs are not that "heavy"
The only thing left to consider is if your portable rig can power them up nicely and you can have Ortho goodness on the go.
