Title says it all. Basically my source device (PCM-D50) is way too powerful for low-impedance stuff. 32 ohm full-sizers, such as the HD215 and even the DT880-32 that I tried once, hold up well (probably due to mid-to-low sensitivity). But not IEMs. Which is why I'm selling the Coppers...
This isn't a problem in winter as I listen indoors or in-car. But in summer I go about with a boonie hat, the round thing with wide brims so full sizers can't fit over them. Besides it gets really hot with the all-black and such.
So my goal is to get high-impedance IEMs. I know that there aren't a lot. Apart from what I listed, what else?
 
PS. The ER4P with the conversion cable really doesn't count. Adding resistors in-line would alter the drivers' response since resistors are not flat overall.

RE262, RE1.
 
ER4P and 4S are only different in the resistors inside the cable pod, and 4S and 4B is different in the addition of small caps.

HiFiMan? No thanks. After their fiasco I'll never deal with them (not that I ever wanted to deal with them in the first place, but still).

What fiasco are you referring to?

Also, maybe the Phonak PFE 121, supposedly it likes power.

I cannot really divulge that since I do not know the authenticity of the source(s) and I do not want to risk legal action. But it was not through espionage, neither did I pay for such information. I personally am negatively biased towards HiFiMan anyway.
But let's get back on track.
Whole thing is that the Coppers, while on D-32, are very balanced. Monster probably tuned up the bass to compensate for (or against) the lack of power in today's DAPs (D-32, while a CD player, pushes a mere 9mW at 16). But when it meets a really good one (PCM-D50, AD8662, 25mW at 16) the "real nature" of the bass shows: Absolute in-ear cannons. The HD215, sounding tinny on the D-32, actually sounds quite balanced (still slightly treble-heavy) with the PCM-D50.
So. Choices? High-impedance.

Well, you are the one that is saying 'what else?'....

Indeed, however I did not know that HiFiMan is going to come up...
