Pros: Well balance, airier soundstage, give every detail
Cons: no deep bass, trebble highest frequency looses detail.
In few words: cheap, great neutral sound, very well built headphones and Soundstage is really great. I love to hear classic music and these were made to be classy. Also love caribbean rythms and let me tell you AKG found a really good detail con percussions and guitars. I found a lack of deep shocking bass, but theres a really defined bass it doesn´t looses any detail. The highest frequencies get some distortion, but the midrange is what they do best.
Great headphones, you need a lot of power to run them fine. I use a Schiit Audio Valhalla and a Cambridge Audio MagicDac100. I could say all together do a very descent job!.
