no 50$ iem can beat any 1000$ iem
i agree some good cheap iem's may be better than pricier ones,sure but don't expect miracles here man.
and matter of fact is that both gr07 and vsd1 are manufactured by vsonic only which makes it even more difficult.
also vsd3 will have a detachable cable increasing its cost of production and its still going for just 60-65$ so yeah i am hopeful but not so much that its gonna topple gr07.
i hope it does,,,but i don't think it will.
as with every iem there will be initial hype just like mh1 hype but i think vsd series is their entry level series and gr series is the top of the line one so there ought to be distinction.
I've heard my share of poor/average performing 1000$ IEMs. Performance doesn't correlate to sound performance, build quality, yes, to some extent. MH1 is still better than say the Ultrasone IQ, which is 1000$
