techPowerUp posted a new article on the Yuin OK1 Earphones

Yuin OK1 is the name of Yuin's brand new top-of-line earphone. The OK1s are rather special since they can both function as a pair of regular earbuds or as in-ears. The design is also completely revamped. When driven by a proper amp the sound is lightyears ahead of any other earbud we have previously tested.
