I don't like to rush to conclusion as often I started raving about some iems that ended few weeks later in the sale forum.
It is really impressing so far. Incredibly transparent and revealing....maybe too much. It has been described as neutral but I think the treble is quite present. Very good recording sound wonderful but I had issues on some albums with slightly "splashy" lower treble. Quite an unforgiving iem. The bass, which I was concerned might be too lean, is in fact absolutely perfect and superb, IMO.
I have been trying many tips but always get a slight discomfort after listening for few hours.
It sounds great through the Z but unfortunately it does benefit from an amp despite being very sensitive and easy to drive (probably due low and uneven impedance) unlike my PFE232.
