Hi there!
 
I'm trying to purchase another budget iem at the moment to add a little variety to my collection of one iem so far (the vsonic GR02 bass). According to the forums, these two iem's are extremley praised
 
I'm thinking about picking one up, but the thing is, two variants of these exist (MH1 and MH1C) and I'm just trying to know the differences between the two. I prefer the look of the MH1 because of the logo and where I can get it, it comes in white (which I prefer) unlike the MH1C. 
 
But I really wanna know what other differences are there? Especially sound quality differences between the two, as that is the sole purpose for this purchase
 
Thanks for the help!
