There is a slight accentuation on the bass which gives it oomph and presence but is not overpowering. Mids on these headphones are recessed, but are still able to present a good rendering of vocals and guitars. The highs are not very detailed, which means that you will miss some of the more intricate sounds from the music, but they are good enough that the overall sound does not come off as too muddy.

Pros
Pro Good sounding bass with okay detail on the highs and mids

Pro Decent all-plastic build quality
Although it's made entirely of plastic, it does not feel cheap at all. The plastics used are of good quality. They can take a significant amount of flex with no signs of breaking.
Pro Can isolate sound well
With the closed back design, very minimal sound can seep into your music. Likewise, sound leakage is kept to a minimum so you won't be disturbing others near you with your music.
Pro Comfortable to wear for hours straight
The 202 II's are really light so you can wear these headphones for longer periods without neck fatigue.
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 Ear cup height adjustment is quite limited
The ear cups are attached to a fixed head band, with a ball socket as the connection. Users then move the ear cups up and down the stationary head band. Available adjustment is quite limited though, so these headphones may not be suitable for individuals with bigger sized heads.
Con Very long, fixed cable
The cable is around 10 feet long. While this can be a good thing for certain uses, the long cable can get tangled up pretty easily and can get quite difficult to manage if you decide to take these on the go. The included cable organizer can help mitigate the problem, but some might find it fiddly to use.
Con Ear cups are quite small
Despite being labeled as over-ear headphones, the cups are actually quite small. If you have larger ears, it is possible that these will fit a little too tightly, if not rest on your ears completely, which you may find uncomfortable.
Con Strong clamping force may cause discomfort
These press down on the head pretty tight, which some might find uncomfortable. With regular use and some stretching of the headband however, it is possible that the clamping force will loosen up over time, resulting in a much more comfortable fit.
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.
