Summary: As a disclaimer, this pair of DT990 was a review unit from Beyerdynamic.
Arrived in a rather large box, beside a high definition picture of the headphones and a detailed technical spec, I always appreciate how Beyer guys honestly describe the sound signature and talk about the comfort without any hype or exaggeration.
Pros: Amazing comfort, revealing detailed sound, great bass response
Cons: no detachable cables, 32 ohm impedance still needs amping to drive from a phone
Summary: I'm in a situation where I generally can't try out headphones before making a purchase so I really have to do my research; and I did a ton before deciding on these.
I wanted a an "open" over the ear headphone with a large soundstage lots of detail and good bass extension. I wouldn't call myself a "basshead" but I know that I also don't care for cans that don't have any bass punch. My initial "wants" brought the 990's right into the picture.
Pros: Slight "V" signature (which I like), Excellent bass extension & soundstage. Great for Rock-N-Roll & Watching Movies.
Cons: Can be slightly fatiguing to some on the high end if not properly amped.
Summary: The DT990 is my first HiFi headphone after the AKG K181DJ and also my ticket into the world of Head-Fi. First off, I have to say that my impressions are pretty consistent with what seems to be the mean impression out here on the web; I tried out al sorts of headphones that were comparable in price before deciding on the DT990. And I know now what it was that made me do it: the amount of detail and air between the different instruments.
Summary: I would make it short.
1.This headphone has strong resonance in 80~100Hz, you would need a very strong amp to overcome the emf, or would got a notable unnatural bump in upper-bass.
2.About the infamous recessed mid- I guess it's a slight,but critical QC fault:
Inside leather bag, the humidity is been lower than normal condition by desiccant,makes the damping coating on the diaphragm lose it's function, just need sometime to got proper work.
Pros: Total clraity tone、ultra transient, froward,focus,but relex present
Cons: Very pickly (about amps), Headband permeant sweat,sensitive about environment humidity
Summary: These are my first audiophile grade headphones so forgive my vocabulary.
I use them primarily to listen to Trance.
I have no other headphones to compare.
They are paired with a Millet Hybrid MiniMax Amp.
I will just say that for my listening choice these headphones feel perfect. The bass is mostly clear and precise and goes as deep as necessary. They bass isn't too much where it hides the rest of the music. It feels natural and just a part of the flow.
Pros: Vibrant, Deep clear bass, sound stage is huge and very accurate, precise no wasted enegry.
Cons: Some sweat and slight ear fatigue (room is hot). Highs can be too high for some.
Summary: It's been a long time coming this headphone, and I've finally pulled the trigger on this pair.
I'm in Australia - where the retail prices of these cans were ludacris (AUD$347) - and they were on 'sale' for AUD$249 when I got them. Still daylight robbery, but I thought for the comfort and convenience of local warranty...
Pros: Soundstage - amazing. Good bass, great separation of instruments, and beautiful albeit recessed mids. Comfort!
Summary: I had this headphone for more that 8 months. All that i have to say is that this headphone have a beautiful look and a very good Quality of materials, and sound that exceed that of the nice "Hifi" sound system of my father and my other headphones (the Beyerdynamic DT770pro/80) for a very good margin and in all the areas.
Summary: Ok lets get one thing straight, these are one of the few headphones that have a realistic and unaccented bass/sub response- something that really gets on my nerves with cheaper models. The pro version is open aired, meaning they arent great for recording musicians, but excellent for editing and pre mixing. I also highly recommend them for any other listening purpose.
Summary: When I first used these headphones they were very bright and the bass was heavily layered almost enough to be described as woolen. But as with all Hi-Fi products they need to burn in, they can’t perform properly until you have about 72 hours of audio burn. I’ve used these for about 20+ hours and they are getting better and better. I own a pair of HD-590's and these are coming close.
