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 Great build quality for the price
These headphones should last you quite a while, as they are built well. The hinges and the headband adjustment are made of metal, with sturdy plastics on the earcups. These should survive being thrown into a bag and minor drops without issue.
Pro Fairly neutral sound
The sound is on the neutral side instead of boosted bass or highs. Overall the sound has good clarity with okay details on the treble along with tight and low-end. The mids are slightly recessed though.
Pro Okay noise cancelling performance
You won’t easily hear engine noise and the like. The active noise cancelling is quite effective at filtering out low-pitched, droning noise.
Pro Can function as Bluetooth or wired headphones
You can continue using these headphones even when the battery runs out. Aside from Bluetooth connectivity, these also come with a USB Type C to 3.5mm cable, so these can be used as wired headphones. You won’t get active noise cancelling without battery power though.
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 You’ll still hear high pitched noise clearly
You may still hear high pitched noise like female voices and sudden bursts of laughter. The noise cancelling is not very effective at filtering mid to high frequencies.
