Compatible with any type of camera smartphone / tablet / MP3 player these headphones immediately exude an excellent quality when printing unpacks. They are a manufacture that has no defects and seem built to last. Equipped with a remote control, so they show very convenient to use. But beyond these initial good "physical" prints, they really make an impression by the quality of sound reproduction. They really make the difference with their competitors: I compared with the same Creative price range and they bury them on all criteria: strength of bass, midrange detail and treble finesse. The NOCS are really in the high end and they prove it with a musical quality excellent. In addition bits provided in several sizes, placement and ensure optimum comfort. You really consider this if one wants to invest in high-quality headphones.
