Pro Fairly detailed and rich sound
The highs are quite detailed, yet do not get harsh. The mids are slightly forward, so vocals and instruments can easily be heard. The bass is not very powerful but is tight, so you’ll get decent punch from your music.
Pro Detailed sound
The CXC700’s sound signature puts emphasis on the treble. It is very airy and detailed, so you’ll be able to hear the nuances of the music. The bass is controlled rather than boomy. The mids are slightly recessed though, so vocals and guitars are not up-front.
Pro Talk Through Mode allows easy conversations

Pro 3 active noise cancelling modes to choose from

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 Control module is bulky
The noise cancelling module can be distracting. It is quite large and heavy, and may pull the headphones down. There is a belt-clip integrated into the design, which may help minimize the issue.
Con The audio may sound lean
If you prefer a rich and powerful sound, then these may not be to your liking. The bass does not have a lot of thump and the mids are recessed, so the sound may seem thin for your tastes.
