100+ Head-Fier
Thanks for the reply,It is difficult to answer this question because, for example, I don't know how the device was used. If you used an IEM on the balanced output in headphone mode, the device operates at maximum power and is under the most load. However, this also means that noise and microphonics become more noticeable, especially since IEMs are very sensitive.
Again, I can't say exactly what you experienced because I don’t know the details, but if you were using an IEM, it would be convenient to listen in IEM mode, where the high frequencies are tamed. They are not missing; rather, you simply won’t get that piercing sound. Instead, the sound will be more similar to that of headphones.
Edit:
I just read your previous post, and I see that you are using the IER-M9, as I had assumed. They have a 20-ohm impedance and likely a somewhat higher sensitivity. If you used the device in headphone mode and pushed it a bit harder for testing (which you normally wouldn’t do), you might have experienced stronger microphonics. I can’t say for sure whether it would be audible through the music and to what extent—that depends on the volume level at which you listen.
The solution would be to use IEM mode, which we didn’t include by accident. I hope this helps at least a little.
Will schedule time to have further investigation on the unit and see how to make it "work" for my use case, can't forget the sound though ..
