i received my AKG this morning and all what i can say is OMG!i am not from the type of guys who say wow these sound wonderful and after one week i go sell them!i evaluate my gears carefully and before i make any purchase i read tons of reviews to see exactly if it will fit my needs.i bought the 701 because the most important thing for me in music is soundstage,airness,vocals.the first impression i got when i opened the box is how big these headphones are.wow.super duper big and first class build quality and asthestics.they look extremly wonderful and world class.then i put them on and i was lost in them.all my ear was inside the pad and the pads covering all my ear,super super comfortable.i then connected them to my micro amp and played "The unforgiven"for metallica because i know this track extremly well and because it is excellently enginered.the first thing i noticed is soundstage and airness.The soundstage and airness involved in the music is breathtaking,literally jaw droping.guitars,cymbals,hihats all sound crisp and very natural,i can hear the pluq of the strings with ease and is very noticable.then comes the bass line about 1 minute i guess and i was afraid of this part because of them being described as weak in bass department.NONSENSE,the bass is very very very very accurate,well controlled,the deepest i have ever heard,impactfull..my sennheiser bass is uncontrolled and bloated and fat in comparison but is more powerful.all over this is one of the best bass i have ever heard,the only iem that i have and can compete with is the fx500 and its wooden house.next up i fired classical music from mozart and Alfie Boe and some jazz and i was stunned.the amount of details that are present and these headphones show is trul unbelievable.they are truly brutaly detailed,every page turn is showed,every one taking his breath or coughing is shown,every blow in a saxaphone is shown...these headphones are extremly detailed.all my classical music is from linnrecords.com.the synergy with the micro amp is out of this world,i use my micro amp with the highest gain around 9 or 10 oclock,these headphones are power hungery and they need powerful amp like the micro orultra micro...aimlink if you have any doubts about these headphones,they should vanish by now,this headphone is extremly neutral and with your headroom amps they will shine.if you have any question let me know and i will gladely answer them.i plan to make a full review because these headphones dont deserve all this bashing,but now because i have exams.
