I have 2 years, it is comfortable and trs does not fatigue the ears. I find it quite prcis, even if the reputable boost a little too serious, I was fine with me. We can remove the cable, for those who are used to walking on the wire! I find this perfect for open headphone costs an hifi and monitoring. and even if not perfectly neutral (considering the price, it must still be reasonable ...), it allows to work long hours without finishing his mix with the headache.
