Noise cancelling in ear headphone 

Description:

From Chinese audio experts ViSang comes the R02, a budget-oriented version of their upmarket R03 offering. Like its big brother, the R02 offers deep and natural-sounding bass, a warm midrange, and crisp treble due to the 10.7mm dynamic driver. The metal nozzles and a Cu-Ag alloy cable ensure longevity.

A uniquely patterned cable sheath provides flexibility and reduces cable contact noise while keeping the cord from tangling and reducing snags. The wide variety of included ear cushions means everyone will be able to find one that sounds, fits, and isolates best. Whether you are an audiophile on a budget or a casual listener, the ViSang R02 will help you enjoy your tunes in a whole new way.
