Seems they finally did launch a Mk4 version.

Also, you used the worst filter (red) in your Mk3 review. You should have tried the black filter (most tamed and neutral) to assess this IEM.

@Bitsir yes, they launch a MK4, they look nice in term of design.
about filters i use them all...let say NX7 whole serie isnt for me. I hate them all. im sensible to timbre, bass roundness-impact and treble control...its just my subjective hearing you know.

@NymPHONOmaniac I'm one of few, it seems, that quite enjoy unique sizzling energy of piezo and not very sensitive to timbre.

I bought the MK4, will try with the TempoTec V6.


By the way I loved this review, very entertaining!
