Usually retailing at $60 USD IMO these are easily the best in ear monitors at their price point.
The sound reproduction VSonic was trying to emulate was the Westone 4R ($500+), to which they came strikingly close.
Some good reviews:

Got one about 1 month ago and I love the high on this phone, you can feel the strings of the guitar and the bass is powahhhh and not muddy. Anyway hope they can release VSD5S in the end of this year.
For anyone love music grab a pair HAVI-B3 PRO (Old Version) for 59$ and it is…. too good to pass….
