I am considering the QKZ DM300 which is 96 Ohm and has a good rating on Vidal's site. I want a higher impedance IEM for the Zishan Z2, which reportedly has a higher impedance output. It's only $6.01 at Fasttech. Unfortunately, I still haven't seen any reviews on the DM300 paired with the Z2.

I would be willing to bet that was supposed to be 9.6ohms (wherever you saw that 96ohm figure). I have a number of QKZ IEMs (including the DM200 as well as the DM300s predecessor the W1 Pro), and they are all 16ohm and under.

So it looks like my observations about Rock Zircons are pretty spot on with the review on aproear.co.uk
http://www.aproear.co.uk/rock-zircon/
Rock Zircon—a strange unnatural sound with exaggerated, pounding bass, thin (though clear) treble and no midrange whatsoever. Lots of folks seem to love these, so maybe it’s me.

And I quite agree on the rating for Swing IE800 which I received today. Been listening to these for a while. I love the soundstage and airiness.

How is BossHiFi B3? It looks pretty and the review on aproear is good too.

The BossHiFi B3 (original model with brown cable) was one of the first earphones I ordered from AliExpress, in late-Summer of 2016.
I really like the way the B3 sounds (it's a smooth and comfortable sound, especially with acoustic instruments & vocals).
Since I wear my earphones & earbuds with the cable over-the-ear, the angled nozzles on the B3 make them a bit harder to fit - but they're small & smooth, so they're comfortable in the ear.

You may be right, and with your extensive knowledge in audio, I would never wager against you. I was just going from the specs shown on both Fasttech and Aliexpress listings. The QKZ W3 uses the same housing and claims 96 Ohms as well. Do you suppose there's any way to verify this?

Well, you could ask @Vidal, since he owns it from the review he did. He could test the impedance quite easily.

I would trust him and his ability to physically measure it, over Aliexpress/Fasttech descriptions (which are notoriously inaccurate).

If you can't directly get a hold of Vidal via PM, get in touch with @loomisjohnson, as he has ways to get in touch with Vidal.

Thanks for the suggestion. I'll try to contact @Vidal to see if he is willing to test the impedance.

Would be amazing if the qkz have 96OHM. Are there no other (affordable) IEMs with high impedance, just earbuds?

I don't know, but I have been searching for some higher impedance IEMs for a while now. Hopefully we'll get an answer as to whether the 96 Ohm claim is correct on the QKZ DM300 and QKZ W3. They are the only ones I've seen with that higher impedance claim.

Man, if something sounds too good to be true, it usually is.

Campfire Comet is 48 Ohm and does require a fair amount of power to really push them. Not exactly a Chi-fi, but one of the few iems over 32Ohm I know of and about the only single BA I know of at 48 Ohm.

Here are some with 32 and above ohm rating:

SoundMagic E80 64 ohm

VSonic VSD2 S 40 ohm

VSonic GR07 Classic 40 ohm

VSonic GR07 Bass 40 ohm

Havi B3 Pro v1 32 ohm

HiFiMan RE 400 32 ohm

i.Valux Hybrid 32 ohm

i.Valux Hybrid Wood 32 ohm

96 Ohm would be a nice option.
