Pros: very airy, pretty balanced and detailed sound with huge soundstage and great midrange
Cons: hard to drive
Setup: EMU 0404 -> Corda Aria -> K501 (ver. 1.0)
This headphone is ideal for acoustic and classical music. I love the airy character of the sound that makes lively. Great for quality live records. Overall detail is very good especially on the midrange. The bass is punchy and full with a powerfull amp.
