Just 5 mins in my ear. i was like, WOW! this is effing good. unbeliavable. I bought HD381 and HD381f, but didnt test the HD381f yet. Yo trio, you said the bass is not that boomy, this is punchier and boomier than beyerdynamic xp1! and it pickups the low freq bass in bass i love you - bassotronics and how low - ludacris. with MYR65, there's nothing to lose. i want to write more, but i'll just keep it and do full review if i have time. ONE SUPER HAPPY BUYER HERE. proud to own one!
