Cool. Thanks! Do you guys know of a glossery to help understand the whole audio-terminology better? I don't find the one here on the forum to be very good.
Try Glossary of Audiophile terms., perhaps
Thanks to somebody on this forum, now I totally understand why certain headphones make people tired while others don't. Human ear has resonant frequency around 6000 Hz. This is way headphones designed not to be causing fatigue have a drop in this freq. range. My Grado SR 225 was making me very tired in spite of having awesome sound which I still miss expecially for heavy metal. Now I have Ultrasones HFI 780 which have exactly same drop around 6000 Hz, but they just don't sound as good as Grado. I've listened to Denons AH D5000 few on Saturday and I have to say that these are one of the best cans I've ever heard. They are also way more comfortable than Grado, exceptionally comfortable I would say. But looking at the frequency response I realize now that they will also be making my ears tiring. And looking at the graph below you can also see why somebody said in this thread that he finds Denon AH-D10001K most comfortable.
He also mentioned Bayerdynamic to me as headphones for professionals which have same drop around 6000 Hz for very same reason. The question for me is which headphones really provide the best of both worlds not causing fatigue while having great lively sound at the same time. Any ideas ?
That will change. The 650 are one of the most comfortable cans in Christendom. Also one of the best sounding.
