Its pros: Sound quality. I use several "ears" of famous brands in everyday life and work, there is something to compare with - for films and music, Audeze is still the best of what I've heard in terms of sound. Some cons: After 1.5 years of careful operation, the left earpiece crackled and began to work twice as quiet as the right one. I can somehow understand mechanical breakdowns, but I didn’t expect this from ears for 30K at all .
