I have used these earphones for 1 year but after that, its one-side stops working and there are some problem occurs in the wire.
when you press or pull then it works. i bought this from Flipkart. it cost me around 1200 rupees now it cost very less.the sound quality is good but sometimes it is not properly working.
it does not have a noise cancellation feature. these are wired in-ear earphones.
if you needed good earphones then go for skull candy or JBL they are much better than this. overall i am not satisfied by this product.
