so it seems that brainwavz is a better option considering the build quality
Not really. I've had the exact opposite experience. I have SoundMagic PL-50 which I love, and are still serving me well for almost 2 yrs now. On the other hand, I've had BrainWavz M3 that broke in just 6 months.
Overall, I'm coming to the opinion that with most Chinese audio products (HiFiMan, SoundMagic, BrainWavz, etc), build quality seems to be hit & miss affair. There's no consistency to speak of.
