MX666 Headphones The headphones are very excellent, with their original packaging, used for only one day. But I no longer need them because I received a gift and I have better ones. I opened it to try it, used for less than ten minutes. Its sound is fantastic and very excellent, and it is considered noise-canceling. On Noon and other websites, it costs more than 66 SAR.
