It really depends on what you're after. The VC02 is brighter, clearer, and more balanced while the VSD1S has more bass and a more v-shaped sound signature. The MH1C is bassier, warmer, and smoother than both these. They are all about on-par with each other in sound quality, just different signatures. Keep in mind also that the MH1C remote only fully works with certain Sony Xperia devices.
I dont really understand those sound sinagtures,sorry for being so noob. Within that price range, can you just tell me which IEM is best for classical music,(symphony, violin, and especially piano, i love Chopin), anime songs, frank sinatra (songs that focus more on the voice of the singer, without heavy background music)
Thank you for the remainder, as I look up about it, Mh1c remote does not suit with my nexus 4.
