Pros
Pro Fairly neutral sound signature
Sound signature is quite accurate, almost flat. Bass is much more controlled instead of boomy, while there is a slight elevation on the highs, resulting in extra energy and detail up top. These offer a nice middle ground between a fun sound and a more reference/analytical sound signature. This sound quality makes the headphones quite versatile as music enjoyment headphones or studio-use cans.
Pro These have a high quality and durable feel
The M40xs feel solid and are known to be quite durable. The plastics used in the build do not easily flex or make creaks, giving the impression that these can last quite a long time.
Pro Can be used in noisy environments
The over-ear, closed back design along with the thick pleather ear pads can block out quite a lot of ambient noise, and will help users to focus in on the music. These make the headphones great for travel or for mixing/monitoring use.
Pro Comes with two detachable cables
The headphones come with a straight cable and a coiled cable, making them useful in the studio or while walking.
Pro Wing tips improve fit
The X2 comes with wing tips that you can attach to the earpieces. The tips enhance the grip of the headphones in the ear, and will help keep them secure even while you are running.
Pro Fun sound signature with lively highs and punchy bass
The highs are crisp, airy and forward so detail presentation is very good. Bass is fast and controlled instead of boomy, so it does not muddy up the overall sound.
This sound signature works well with a wide range of genres and rock, pop, hip-hop and EDM will definitely sound great with these headphones.
Pro Allows taking calls
Integrated into the remote is a microphone, so you do not need to pull out your phone should a call come in. Mic quality is pretty decent, and your voice should be easy to understand on the other line.
Pro Stable wireless connection

Cons
Con Incompatible with cables from other brands
Only Audio Technica cables can be used with these headphones.
Con Spotty battery life
Jaybird claims it has 8 hours of playback time, but many users get only around 6 hours. There have been instances where the X2 gives even shorter battery life, with some users only getting around 3 hours of use.
Con Awkward mic/remote settings
Coming from the iPhone's mic/remote can be a bit awkward. The Jaybird uses a long press and hold on the volume up and down to skip songs.
