Question Ranking
Pros
Pro Not tiring to wear
The HD681 will not put a lot of strain to your neck and head, even for long periods. Coming in at around 220 g, they are relatively light. This is due to the use of plastic as the primary build material, along with small metal tubes on the headband frame instead of large plastic or metal parts.
Pro Bass and treble are emphasized
These headphones have what is called a V-shaped sound signature where the bass and treble is boosted while the mids take a backseat. The bass is powerful, deep and satisfying. Listening to bass heavy music will certainly be a good experience. The boosted treble makes audio detail up front, so nuances in the music can be clearly heard.
Pro Fairly wide soundstage
Due to the semi-open design, the sound is not completely trapped inside the ear cup housing. This gives the sound a wider, more natural feel.
Pro Full and warm sound despite the small size
The drivers may be small and thin, but there is good bass presence.. The mid-range may not be the most detailed, but there is a smoothness to it that gives the sound a warm and pleasing quality. There is a slight roll-off to the high frequencies yet detail and extension is still good . Overall, these headphones can give a fun listening experience that can work well with all genres of music.
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.
Cons
Con May feel cheap and flimsy
The plastics used in the construction of these headphones are not of the best quality. They feel flimsy and will often flex and rattle.
Con Thin ear pads may cause comfort issues
The ear pads are made of cheap feeling synthetic leather which can get warm rather quickly. To potentially add more discomfort, the cushioning inside these ear pads is quite thin, and can hurt the area around your ears when worn for many hours straight.
Con Mids can be lacking
Some may find the mids to be inadequate. Vocals, guitars and other sounds in the mid-frequencies may sound distant or too soft.
Con Treble can be harsh
While the bass benefits greatly from the V-shaped sound signature, the highs are boosted by quite a lot, and can make the treble sound too harsh for some. Cymbal hits for example can be too washy and near distorted and can be fatiguing.
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.
