Pros
Pro Balanced sound signature with a good level of detail
There is no harshness to the highs, the mids are clear and the bass has good oomph without the bloat. Detail from these headphones is also good, with instruments and voices sounding clear and well-defined.
This sound signature can work fairly well with all types of music, though if you really want boosted bass or highs for certain types genres, then these might fall short of your needs.
Cons
Con Stock ear tips are not great
The included ear tips are quite thin and squishy. They are not able to provide a good grip while in the ears, and can make the earpieces prone to falling off. These tips also adversely affect the sound so using better quality ear tips will result in noticeably improved audio.
