I'm upgrading from base level pair of Audio Technicas,
and am stuck between two great pair of cans; the Audio Technica ad900x and the Beyerdynamic DT990 Pro250. Both have excellent reviews and can be bought for about 150-200 US dollars. I understand the drawbacks of open ear phones, but I am very interested in the detailed highs and open "soundstage".
I will be using a cheap e06 fiio driver and mp3s for the time being. I will be listening to anything from light rock to electronic soundtracks.
What kind of sound upgrade am I looking at from my old, but reliable cans, and which do you guys think is the better choice. Please excuse any of my ignorance toward the subject, and all help is greatly appreciated!
