Pros:
Bass quality is good, gives softer sound.
Build is strong as I throw them everytime but nothing has been happend to the speakers.
Jack quality is good . Never got any problem with the tear of wires inside the head of jack.
Passive noise cancellation is present.
Very comfortable in ears, better than in- ear earphones as the cause pain in ears.
Cons:
Active noise cancellation is not present.
Passive cancellation is not as strong as in-ear earphones so there may be some background noises.
