DT-1990 Pro 250 Ohm : I love these headphones!

These are absolutely amazing! They will reveal any issues in the mix very accurately. They have that peak at 8khz but it will only be present on too trebly records. You have to keep that in mind when mixing though. They have amazing bass response up to those very low end. The clamping force is strong so I personally stretched it a couple of times to loosen that grip and they are perfectly fit now. I feel like on most cheaper beyerdynamics the clamping force gets too loose after some time. Here it may be just perfect after a couple of months, I guess thats why its such a strong grip to begin with, its supposed to be more comfortable over time. My clarett pre usb drives them very well. My phone drives them easily as well, but they lose (about 7-10% I would say) of the soundstage and detail they have. My computer direct audio drives them ok, but you can hear the audio card is cheap when plugged into, the sound feels slightly more robotic. I made a comparison side by side of those against the Audeze LCD-2 which is twice the price, and they sounded pretty similar in terms of overall audio quality. Of course the Audeze had a 5-7% wider soundstage (as you would expect from planar headphones), but the details and stereo reproduction was at the same level. You can tell exactly from which angle comes an instrument with both with the same accuracy. LCD-2 sounds darker, they dont have that 8khz peak. The dt1990 overall sounded more exciting due to that peak, which may be a good thing for solely listening to music, but may be a slight disadvantage in terms of mixing audio. The sound is a little colored in the treble which may result in producing slightly darker mixes if this feature is forgoten. This is why its always recommended to mainly check audio from monitor speakers or use eq passive or active eq while using the dt1990. Nevertheless compared to a classic with twice the price (Audeze LCD-2) those headphones did not feel any worse, just slightly different. I think this says a lot about them. I love mine and the fact that they come with lots of accessories is incredibly convenient. I let my girlfriend use them a couple of times, and now she wants them as well... :)
