KRK KNS 8400 Professional Monitoring Headphones
KRK KNS 8400 Professional Monitoring Headphones is rated 5.0 out of 5 by 1.
Rated 5 out of 5 by from Wow. I get to rediscover my music collection!Wow. I get to rediscover my music collection all over again. I had pretty good headphones before this set, but these are so revealing of subtle details in the music that they are a treat to listen to. These beat the heck out of my old Koss pro recording headset that cost me over $350 I got a few years ago. They seem to disappear when listening. I like that. For their size they are pretty light and very comfortable, one of the more important things with full size headphones. As expected, they are a bit inefficient, but all good speakers and headphones need power to be able to do their job right. They also need some break-in time too. Give it about 20 hours of so.Whoever says these have no bass is full of baloney. The extension on these headphones is impressive and yes they really DO go down to 5Hz without any false or overdone character and the level is consistent regardless of frequency. Dang. I'd like to see a good set of speakers do that. Sounds very similar to my Dahlquist DQ-1W for its neutral sound that any seasoned audiophile will appreciate. At first they may SEEM to have less bass but what you are hearing is what is actually in the recording as truly good headphone should be, with as little coloration as possible and no sound of their own. I played a few tracks from my Michael Murray pipe organ collection and the low end is pretty staggering in how low they will reproduce bass and do it with no effort and the detail is extremely accurate. Lee Ritenour's 6-String Theory came to life. Percussion sounds spot-on and exceptionally clear and hits you like a brick if you got it turned up. Kick drums come though with a superb low end that is not bloated or false. Male vocals sound like they are there singing to you in person. I was able to hear the sounds of Lee as be breathed while playing a solo of Caprices, Op-20 No 2 and 7 and his sleeve moving on his guitar. Never heard that before until now. The highs are crystal clear with no harshness and again, very neutral.Dawn Upshaw's album World So Wide was a good test of female vocals. Her vocal range can sound a bit screechy on a lot of headsets and speakers but again, she came through in full detail with NO screechiness and sounded like she was there singing to ME.Just for fun, I tried Mobile Fidelity's Thunderstorm on CD. It sounded so clean and real I started to feel cold and wet from just listening to the rain. That's creepy. But that's what I was looking for.These headphones definitely will do justice to all audio. KRK got these right. Do these headphones justice and get a good headphone tube amplifier worthy of these. You will be amazed and enjoy rediscovering your music collection too.If you want to hear what is really there as the artist and engineer intended, BUY THESE. YOU WILL NOT REGRET IT.
