@kenpachiroks, I agree. Back then, M2 was for $50 what RE0 had done for $100 a while back. But, now we have a few budget options around $40-60 with competition intensifying by the day. But, there is also a difference which must be highlighted when it comes to M2 and C-12. Brainwavz Pro Alpha, M1 and M2 were just re-brands of the Visang IEMs which were already selling in China. SA's IEM is made in China, but was independently conceptualized and designed in India. This requires lot more effort. I think I am going to stick to 'random thoughts' kind of impressions from now on. It is becoming increasingly hard to find those continuous, uninterrupted hours that I need for a proper review. With too many things clashing for attention, I find it hard to sit down and do comparisons. I therefore am officially announcing my immediate retirement from reviewing. Would need to send back C-12 at the earliest!
