The microphone works well for remote call or change music, saw no difference in quality of the microphone over to my old pair of yet more expensive headphones.
Sound by listening to music is very good value. The in-ear noise cut well, it is a treat in transit and allows not to sound too loud.
A nice enough in the box, there were spare bits and two other metal ends to replace a portion of the earpiece.
For the price, they are all for the sound quality for aesthetics.
