Frequently Asked Question

The iEmatch is a purely passive device.

It cannot by itself produce distortion.

Any distortion observed is from the driving amplifier.

Question: I tested mine with an IEM that's sensitive also, it lowers the volume like an adapter, but it introduces distortion?

Answer: It may be that you used a lot of attenuation and then cranked excessively. The amplifier is likely to distort, this is not uncommon.
