Great headphones with great acoustics.

Absolutely phenomenal headphones for the price. Definitely more treble-heavy, but its not ear-piercing so I'm happy. For hi-fi listening, these are insanely good. Cannot say much more, if you got the money, buy these suckers.

Love these Cans

Great cans love how replaceable the parts are. Great Stuff and comfortable.

My go-to choice of headphones!

I would easily place this pair of headphones at no.1 out of every pair of headphones I have ever tried, or ever will try. The DT 990 Pro's offer an excellent frequency response and accuracy (though the high ends are quite sharp, for users who are constantly switching between headphones). The comfort factor of these headphones is second to none, it is incredibly comfortable on the ears which is vital if you're working on / listening to stuff for pretty much the entire day. One observation on the DT 990's for me is that you could leave them on and not even realise they are there: being open back headphones, you can hear your surroundings much clearer and louder than closed back headphones.

I wouldn't recommend using these headphones in a busy and loud environment (i.e in public, a studio where musicians are practicing and such) as you may not be able to pick up on every detail on whatever it is you're listening to and monitoring- which is exactly what these headphones are designed to do and do so quite incredibly. For someone who is always on the road producing (which is a great idea, if it works for you), this may not be the best for you for the fact that these headphones pick up a lot more surroundings and noise than others.

I very strongly recommend these headphones if you are a bedroom producer, a mixing engineer or whatever the sort for all round studio work, but especially for mixing and mastering to pick up on every detail in the mix. As someone who works in a bedroom and a quiet household, these headphones suit me perfectly and honestly? I would be willing to pay a higher price for these amazing quality headphones from Beyerdynamic.

Best at the price range,

The stereo separation is amazing and it has a decent bass response. I felt the highs are really ear piercing and they should be tamed down for a better listening experience. This is probably the most comfortable headphone I have ever come across. I can go with it for almost 8 hours straight with minimal listening fatigue.

Preferred Settings + Usage:

Very good sounding headphones

The 990 is an open headphone with its advantages and disadvantages. While the sound quality is unbelievable, great response, balanced frequency response it lacks isolation. Using it for monitoring applications while recording is not a good idea as your microphone will pick up whats heard in the headphone. Nor does it perform well in noisy environment. Or might disturb your sleeping girlfriend in the room. :) They are perfect for mixing and mastering (as perfect as headphones can be) where no isolation is required.

Great Quality Mixing Headphones

Because these headphones are open back, it is not well-suited for recording. However, it is one of the best budget mixing headphones because of its open back construction. Also, these headphones will considerably be lower in volume than other commercial headphones because it has a much higher ohm level.

Too much High-End

Use these only for Mastering. My ears are severely damaged and these headphones really hurt, if you use them for extended periods. Better use Headphones with a flat frequency response.

Takes breaks and protext your ears!

Stunning

After having a cheap and broken setup for audio for years I finally invested in these. And I was floored by the quality I was getting as compared to other headphones I had used in the past. Outstanding quality for the price.

highly recommend

For the money I think they're the best there are. Make sure to plug them do a decent source with enough power to properly drive the 250 ohm drivers.

Great headphones for mixing and mastering!

I really enjoy both just listening to music and producing music on these headphones. Not much can be said about them, except that they produce clear, neutral and detailed audio quality. They can also hit the very lows and the highs for precise mixing. They also come at a pretty fair price, and are constantly on sale, so if you can, please consider getting a pair of these amazing headphones!
