Below are excerpts from the review:
I tested the DJ44S with a new IEM I happened to have on hand for review, FIR Audio’s e12 (review coming soon). Out the box and using its stock cable, this IEM is quite bombastic, revealing, and – for want of a better word – edgy. Some of its tuning quirks push the sound to extremes, which makes it quite easy to hear where the grounding changes occur.
With the DJ44S in play, I hear a cleaner sound. The slight grain I picked up in the midrange and treble frequencies using the WM1Z in its ungrounded state is significantly muted with the adapter in place. This results in a less fatiguing sound, and an easier appreciation of the e12’s inherent resolution. The darker background also makes some details easier to pick out, and stage feels slightly expanded in all dimensions.
