Hey
@Mimouille! Just noticed you online viewing this thread. As, AFAIK, the only SE5U owner apart from Nic in this thread,
1) How would you compare it to the Zeus-XIV and Zeus-R, and the VE8?
The VE8 is comparably enjoyable, more colored, more fun, and technically just as proficient, but in a less reference way. The R I dislike...it is like the XIV without the good stuff. The XIV is lovely but overly sensitive to me. It beats the SE5 in overall resolution I think. The SE5 sounds more refined and delicate than any, IMHO, due to unique combination of great extension, non agressive ultra detailed sound and natural tone.
2) Do you find statements regarding the SE5U's lack of treble or speedily-decaying treble to be true? Not at all
3) Do you find yourself listening to the SE5U with louder volumes than the aforementioned three IEMs?
Higher volume notch but comparable volume. The SE5 is much less sensitive.
4) When listening to stuff like cymbal crashes, do you find the SE5U's darkness to induce a dulled, veil-like effect? Not at all.
Please do keep in mind that I'm inferring these aspects of the SE5U from other posts, but I'd love to know the answers to these questions (as would, I'm sure, most on this thread). Thanks in advance!
