I know it's a slightly old thread, but I'm bumping it up again!
So far, the order in which I've bought my 'audiophile' headphones has gone as follows (from 1st (top), to most recent (bottom)) :
Beyerdynamic DT431 (unfortunately no longer with us
Sennheiser HD595 (still wear, in bed of all places!)
Grado SR325i (sold)
Sennheiser HD650 (sold)
Beyerdynamic DT990 Pro (selling)
Sennheiser HD600 (selling soon)
... and I'm back with my old AKG K701s, which I've constantly been a bit unsure about. Well, I've just shortened the cable to 5ft, reterminated it with a 3.5mm (1/8") Switchcraft plug, and I've completely fallen in love with them.
Maybe it's my current amp (iBasso D2 Boa), maybe it's insanity, but they just sound so good. My main annoyance with the HD600 which I was using up until yesterday was with cymbals on all my recordings. They sounded too unrealistic, jittery. With the K701 they sound lifelike. I even thought they lacked bass last time I used them, but again I'm finding the bass to be so perfectly formed - not exaggerated and unclear like the DT990 Pro, just right. It's there, it's not in your face, it's just how it should be.
Can't believe I've tried so many sets and ended up with them being my favourite set again - I think part of the problem was reading reviews which call them bass-shy... but at least I can put my hand up now and say :
I've owned a decent selection of headphones, and I reckon the K701 is awesome!
