if I have to describe these headphone in one word it would be `` impeccable '' . you would be hard press to find a more comfortable pair of headphone with this kind of extraordinary sound quality for anything short of $ 500 . if that be not a testament to the value of these headphone , then I do not know what be . I could go on about how you should use a dedicated amplifier , how the sound be lively and exciting without be overpowering and that you low bit-rate mp3 and aac file will not do these headphone justice , but I 'll leave that to the expert who have already post incredibly detail and thoughtful review . point being , the sound will only be as good as you source file and choice of amplifier to drive they . unless denon release new model or the price of the ah-d5000 or the ah-d7000 model drop significantly , I would recommend these headphone to anyone shopping for a closed-back design with a modest budget .
