HiFi Boy is a new Chinese company that started not too long ago. They produced the HiFi Boy OS V3 as their first iem. Next, they produce the OE8 as their flagship iem.  I would like to thank Penon Audio and HiFi Boy for this loaner unit. At the moment, you can purchase the HiFi Boy OE8 from Penon Audio .
