A good amount of noise will be blocked from mixing in with your music. Loud, low-pitched sounds may still be clearly heard though

Pro Exceptional mic
The microphone has good clarity and can actually be used for tasks other than talking on the phone - like recording podcasts on the go for example.
Pro Comes with two different cords
One cord comes with an inline mic and with controls, and the other cord is your standard audio cable. This inclusion not only allows you to pick a cable to best suit your use-case for the headphone, but this also ensures that you have a spare cable should one get damaged.
Pro Good bass reproduction, warm mids and smooth highs
The bass of these headphones is pretty good. Bass drum hits have good power to them, yet they do not muddy up the sound. The mids are warm and forward, and should present vocals and mid-range sounds quite well. The highs do not have a lot of sparkle, but they are clear and present a good level of detail.
Pro Can effectively cancel out noise
With these headphones it will be much easier for you to focus on your music, or whatever it is that you are listening to. Combined with the closed back design, airplane/train/bus engine noises are effectively cancelled out.
Pro A good number of accessories are included
Along with the two headphone cables, you get a carrying case, an airline adapter and a 6.3mm plug. These should help make the headphones easier to transport and also make them compatible with a wider range of audio sources.
Cons
Con Limited inline controls
The inline remote only allows you to play, pause, and skip tracks. You can’t control volume levels though.
Con Requires an amp for optimal volume/sound quality
If you really want to get the best sound quality as well as volume from these headphones then you will need a decent headphone amp. The impedance of these headphones is quite high at 300 Ohms, so these require a good bit of power to function optimally.
Con Can get uncomfortable for people with larger ears
The ear cups of these headphones are quite compact, and may rub against the ears of some users, which can get quite uncomfortable.
