Disclaimer, what I share is just based on my own perceived hearing and experience when compared to past IEMs I'm very familiar with. YMMV.

In point form;

- Soundstage and imaging that surpasses triple fi 10 and vsonic gr07

- Balanced and slightly U shape signature. But odd enough sound signature changes based on what music/quality you feed it.
  Especially the mids. Sometimes its forward, sometimes recessed, sometimes just right.

- Sparkling and airy highs, might be a tad bit to bright or hot. More than 100 hours of burn in a must to fix that up.

- Accurate and smooth mids.

- Bass that is better than Sony XBA-4 and triple fi 10 but still not basshead IEM.

- Sounds as if I'm listening to BA iem even though this is dynamic.

- Black background, instruments and voices are spaced apart in a very interesting manner.
  At first this may be weird or people might mistake the IEM to be muffled or veiled. Brain burn in needed.
