This sound review will be based on the NOS setting activated, with HDR: ON. I have only used IEMs during evaluation. (HDR: Off makes FC6 too susceptible to noise from the source (phone/laptop), introducing artifacts such as pops, crackling and a very loud noise floor. It is only really useable together with a VERY clean source.) + Rich, Velvety, Natural, Analogue, Liquid R2R NOS Timbre When HIBY FC6 is run in NOS mode (No-Over-Sampling), it takes the signal as is and peddles it forward to your connected IEMs/headphones without tampering with it...

+/- Transforms When Given Power: This is both a pro and a con. Well, I guess it is more of a con than not. You cannot judge this IEM driven by a dongle off of a phone. This IEM will not fully wake up even if you plug said dongle to your laptop. Sure, it gets loads better, but it is still only halfway of the performance it is capable of. It scales very nicely with more and better power and gear. This is why I refer to it as the Sleeping Panda, because It really wakes up when fed and I suspect many people have only met the Sleeping Panda so it is...

+Wide Open Headstage: Since the Wind is open-backed, notes can decay naturally and infinitely without a sense of hitting and bouncing off the backplate. This adds to the timbre decay which ends up being so natural that you've never heard it. It has a circular headstage where it is as tall as it is wide, and it is very wide with quite good depth. What is more, it is incredibly open-sounding where you can't sense an obvious end to the stage, beating out even full-sized headphones such as HD650 or Hifiman Ananda in terms of how notes decay outwards.
