I've tried both the white 680 ohm resistance filters and without filters at all, and neither sound as good as the stock brown 1000 ohm filters. The white filters do sound close to the stock, although the upper mids sound more emphasized and bass sounds tighter with less emphasis. With no filter, I heard more balance with all the frequencies (sometimes it sounded as if frequencies were bleeding into each other: lower/upper minds and treble) but less dynamics as if the life was sucked out. Treble was more splashy and a tendency towards sibilance.
I have an Ibasso CB12 cable that cost a total of $109 that I really think brings the best out of the UM 50 Pro. It's a copper/ silver plated copper-copper weave cable. It sounds to me like it adds some extension both ways without sacrificing the gorgeous mids. I would have loved to have sprung for the $200 CB13 which is silver/copper, but it's just too much for me to spend on a cable.
And if you are using foam tips, they do tend to muffle treble in my experience.
Obviously, I threw my caution from my previous post to the wind and removed the filters with the tool from Aliexpress problem-free. It was much easier than past experience. It just proved to be a waste of time. Removing them altogether or replacing with the white altered the tonal balance a little bit, but in each case it sounded "off" to me.
