I still havent bought my headphones, im starting to look into the DT 770 250 ohm but my only concern is the lack of a detachable cable, as i said before i will use them mainly on my computer, but up to two times a year while traveling. What do you guys advise me? The DT 770, momentum, v-moda, MDR 1a, solo 2 or ath m50x?
