Pros: Amp optional, Value, Comfort, Sound
Cons: That plastic feeling.
I could not recommend these headphones more, they sound better than anything else i have had the opportunity to listen to for more than five minutes. They take the best parts of the headphones i owned previously and puts them all in one package and refines them even more. More controlled lows than the m50, better highs than the ad700's and keeps their sound stage, and the mids of the MS1 with more detail. Just an incredible headphone.
Buy these now.
ALSO: I bought my pair from videopro in Australia, and they arrived the next day with free shipping. There was very minor damage to one corner of the beautiful packaging but for the most part I am a very, very happy customer.
