Audio123 described the Nova as technical and thats a fair assessment, as some described the Andromeda as holographic.
It is a fairly even IEM overall.
Bass and treble are moderate.
The bass can be increase or decreased via tip rolling.
With the stock tips the highs are airy and realistic than extended.
I had a good listen yesterday on my many commutes and found I could use the M tips instead of the L size. Much better.
I also fell asleep on the train twice....with the Novas in.
An IEM you can sleep on? I'm happy to hear that, I often slept with my IEM on during commute.
