woah.... 90hz roll-off is pretty high. Well above what I consider sub-bass.Just received the OPUS1. Very neutral sounding indeed and unlike anything I've heard before from a single ba iem. They are not very powerful or forward-sounding and sibilance is almost absent, thereby minimising ear fatigue and making the iem comfortable for long duration listening. Soundstage is wide and spacious with a sense of surroundness most probably due to the slight echo effect that can be heard. Bass is lean and somewhat detailed but fans of the FAD BAM effect (comparison to single ba) will likely be turned off by the OPUS1 less
impactful bass.
One point to note is that the
unique wavy shape might create a fit issue for some people affecting the bass and noise isolation. Foam tip (non stock) solved this issue (semi-full fit) for me but due to the thinner then usual nozzle, you will have to force the tip further up the sub-housing to secure it in place.
Personally, I found the OPUS1 to be a little tad boring which is expected of a flatly tuned iem but this would be my choice of iem to bring onboard a plane and fall asleep with. At around US$217, I would say there are better value for money iem out there but if you are a sound purist collector in search for the perfect single driver iem, this very unique OPUS1 is definitely a keeper.
