Pro Lifetime warranty
Koss provides a lifetime warranty for these headphones.
Pro Can be folded down to a very compact size
The ear cups can be folded into the headband. This further reduces its already slim design into something that is much more compact. When folded down, these headphones can easily fit in small bags.
Pro Can accommodate a wide range of head sizes
The headband can easily be adjusted to fit a user's head. The assembly features sliding metal pieces which can easily be set to fit small to large heads.
Pro ComfortZone system allows extra fit customization
Aside from headband adjustment, users can also adjust the clamping force of the ear cups using the Comfort Zone system. This changes how secure the ear cups attach to the headband, which results in either a loose or tight clamp.
Pro Can turn heads due to their retro design
These are eye-catching headphones because of their retro design. The unusual shape of the driver case and the blue accents definitely make these look unique.
Pro Has a durable and reliable feel
These headphones may look thin and flimsy, but are actually much more durable than their look suggests. The headband is made out of metal and can take some flex without snapping. The plastics used also exude a quality feel.
Pro Carrying pouch makes these easy to travel with
When used on the go, these headphones get extra protection from the included carrying pouch. This pouch looks simple and is made out of pleather, which should protect these headphones from scratches.
Pro Well-built
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.
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.
Pro Wide soundstage
The audio from these headphones will sound wide and quite immersive, which can be attributed to the open-back design. This also results in good instrument separation, so you’ll be able to easily identify the directions where the various sound sources are coming from. The wide soundstage can result in a truly immersive music listening experience, and also makes these headphones a good choice for movies and gaming.
Pro Soft on the head
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.
Cons
Con Danger for hair
Hair tends to get snagged on the metal headband which can get quite uncomfortable.
Con Not much power to the sound
If you are looking for headphones that offer a lot of thump and a lot of detail then these are not for you. The headphone drivers are too small for big and detail-rich sound.
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.
