Wow I was so excited about these headphones and all the good reviews that were posted. I got them and tired them on but only one ear works and the sound is horrible not high quality what so ever. These are definitely defective. They are weird in the sense that you have to use an aux output cord to connect these, granted the cord is included but with my experience sound quality of aux isn't the greatest. I also bought a pair of matix domepiece headphones and they are by far superior than the Nixon's.
