This one also has the gigantic spike, perhaps similar to the first one.

I still think they're doing something incorrectly --- it's clear that guy is "SoonJa" as quoted in the Seeko reviews. One criticism I have about what they do is that they push the drive power far too high, at 1 mW, which sends everything into distorting madness, ruining a useful look at distortion profiles.

Also, I'm no rabid Jerry Harvey fan, and especially because of their business practices I won't be getting anything from them any time soon or ever, but I just can't plausibly see the Roxanne looking like that in a real ear. It doesn't measure like anything I've heard it sound like, and the choice of drivers, although excessive and definitely does tend toward that way in measurements:

Allow me to slot in my impressions:

Roxanne (Universal) vs JH13Pro (Demo):

Roxanne has this kinda weird hi-sound, like for eg. the hi-hat sounds too splashy compared to JH13Pro, which is to me an alright quantity. The bass is weird too, like felt smaller sounding yet not so tight. The stage has somehow widened because every instrument sounds "smaller" to my ears. 13 sounds rather clean and every instrument is clearly in place. Even the vocals have good breathing sound which i like very much.

The store advertised it as the Rock star IEM. I guess YMMV.

I heard the bolded parts opposite from you for some reason. Hi-hats come off less splashy in the universal Roxanne than the JH13FP demo, while the Roxanne at bass minimum still has more quantity than the JH13.
