The headband also features similar cushioning materials and minimizes pressure spots on the head.

The open ear cup design allows the sound to blend with your surroundings, giving it a natural width. It will also be easier to identify the direction of sounds, which can really help immersion.

Pro Headphone cable can easily be replaced
While the cable connectors are proprietary, they can easily be removed from the ear cups with a firm pull. The popularity of these headphones means that there are a lot of aftermarket cables that can be bought.
Pro Full and rich bass with very detailed treble
The low frequencies are what stand out from the sound signature. The bass is powerful, deep and tight so you get a lot of thump without muddying up the overall sound. This is complemented by very detailed and airy high frequencies, so you should be able to easily hear the fine details from your music.

You can wear these headphones for many hours straight with little to no issue, as the head band and ear pads have thick padding. The ear pads have a suede cover which allows some airflow to the ears, and helps minimize heat build-up.
These headphones should be able to withstand minor impact and drops, and will last you years of use. The headband and yokes are made from solid yet lightweight metal, so they won’t break easily. The ear cups are made of plastic materials which, while not as durable as metal, are strong enough to not come off as flimsy.
Con Sound leak can be a distraction for others
The open design means that a lot of sound can leak out the ear cups. Other people in your immediate vicinity will be able to hear your music, movie or game, which can be annoying for them.
Con Requires a headphone amp for optimal sound
Plugging these directly to your computer or phone will most likely result in audio that is lacking in volume or may sound too thin. To get the best listening experience, you will need to run these with a capable headphone amp.
Con Requires a headphone amp
You won’t get a lot of volume and a good music listening experience from these headphones when plugged straight to your phone or computer. These have a high impedance rating so you’ll need a powerful amp to run the DT990 properly.
Con Leaks a lot of sound
The DT990s are not ideal for use in an office environment, if you share your space with others or when traveling. These headphones are fully open, so they leak out a lot of sound, which can be annoying to others.
Con Tight clamping force
You may find the clamping force to be quite tight, especially if you have a fairly large head size. This can make wearing the headphones for hours straight uncomfortable, even if the padding on the ear cups and headband are quite thick.
Con The highs can get quite sharp
too boosted and harsh, which can feel fatiguing.This can be apparent if you listen to more aggressive styles of music like rock or metal, or music which involves a lot of cymbals and high-pitched instruments.
