Specs
Ranked in these QuestionsQuestion Ranking
Pros
Pro Neutral and detailed sound
Treble is quite detailed, but lacks a bit of sparkle on the highest frequencies as they are rolled off. The mids are just right, not too forward and not too rich. The bass has good presence and punch, but is not very powerful.
Pro Very good passive noise isolation
Its closed back design along with the fairly thick, leather-surfaced earpads are very effective at keeping the music in and the ambient noise out. This is very useful in tracking situations, and will also help you focus on the audio even when in a busy, noisy place.
Pro Fairly comfortable on the head
The headband and ear cups have fairly thick padding to ease the pressure on the head. These are covered with leather material so they feel smooth.
Pro Sounds great even without an amp
A headphone amp is not required in order for these to pump up good volume and sound details, so these can work well off of portable devices. There is a noticeable improvement in sound quality and volume when used with a proper amp though.
Pro Build is solid and feels durable
A combination of high quality plastics and metal are used for these so there is minimal flex and rattles. The headphone joints and yoke also have smooth movement, which make these feel premium when held.
Pro Cables are easily replaceable
The cables can easily be detached, with 3.5mm jacks as ear cup connectors. This makes looking for new/replacement cables very easy.
Pro Can be used for taking calls
Stock cable has an in-line microphone. Not only is this convenient for taking calls while listening to music, but the mic's sound quality is good, with voices sounding clear, full and with good volume.
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 Headphones may feel warm and sweaty quickly
While the leather surfaces feel soft and smooth on the skin, they also trap heat very well. You may feel the warmth building up quickly around the ears and on the head. This can also be an issue if you sweat a lot.
Con Ear pad openings are quite small
If you have large ears then the small ear cup opening may be a problem. They may feel tight around the ears, or even sit on your ears instead of go over them, which you may find to be less than ideal.
Con Weight is on the heavy side
The use of metal and quality plastics on the headphone construction, as well as the magnets in the drivers contribute to a hefty weight. While this is not a problem to wear for short periods, you may feel some head or neck strain when using the headphones for hours. This also makes the headphones an extra challenge to bring on the go.
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.
