The VSD1/S has better sound quality. GR02 has the same cable and as far as the build quality of the housing it's a bit more solid given it's bigger and the front part is metal while on the VSD1/S only the nozzles are metal. On the other hand, the GR02's housing sticks out of the ear while the VSD1/S' is flush with the ear and has the cool rotating nozzles.
I have the GR02 bass edition and the VSD1. The GR02be has colder and clearer sound; while the VSD1 has darker and warmer, therefore muddier sound. What I don't like about the VSD1 is the extra midbass, I consider it a bit bassy for my personal taste, I should have gone with the VSD1S instead. My music preference is rock/metal.
I have 2 friends (own cheap $10 in-ears) try on the GR02be and VSD1, and they prefer the GR02be. Their music preference is main stream pop, k-pop.
If you don't want to spend an extra $10 I believe the GR02be will be good enough, or get the VSD1S. You won't go wrong with either. Also, check out lendmeurears.com, they're having a sale on Vsonic models.
what exactly is the earclip for? is it to make the earbuds behave more like these so they fall out less easily? I'm leaning towards the VSD1s cuz of the earclip, this thread, and seems lighter than the GR02
