Hi Friends! This is my first post in the forum. Nationite is a nice re-branding company based out of Hong Kong. If the pictures are indeed of Brainwave M3, then it is indeed a Visang VS-R04, a popular OEM Chinese manufacturer. R04 were touted for their high quality material as similarly found in the flagship model of Denon IEMs. Here is the details from R04 and can be seen they match exactly the specs of M3....
