Pros
Pro Impressive isolation and minimal sound leakage
These Beyerdynamics offer impressive sound isolation, keeping exterior noise out and your music in.
Pro Sits well over your ears
The DT770s are very comfortable to wear with deep and spacious ear pads. The velour material used on these are smooth and breathable, and the thick foam provides ample cushioning. These headphones can be worn for long periods of time with ease.
Pro Good soundstage for closed back headphones
The DT770 Pro, when amped properly, creates an open feeling sound stage that is very impressive for a headphone with a closed design.
Pro Great sound quality with deep and powerful bass
The bass is not overpowering. Instead, it is clean and controlled. The overall sound signature is focused on the bass but the mids and highs are in no way lacking either.
Pro Good sounding bass with okay detail on the highs and mids
As expected of their price, these headphones are not able to deliver a lot of detail, clarity or accuracy in terms of the sound but they're still quite fun to listen to. 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.
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.
Cons
Con May require extra power/amplification for optimal sound
Depending on which model is purchased (16/80/250-ohm), your system may have trouble powering them to get a full sound and comfortable volume. 16/80-ohm should work fine in most systems. If not, you may need an external amplifier.
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.
