So I really like the EP10 the more and more I use them. This is easily my favorite 11.11 purchase, and worth every penny of $4.80!
Here's some observations:
1. The comfort is off the hook. The angled nozzles allow the IEM to sit at just the right angle, and the straight leg on the bottom of the shell tucks securely into the intertragic notch. I have been wearing them for hours with no discomfort whatsoever.
2. The EP10 are perfect for music that is traditionally bass light, such as 60s-80s rock. They fill in just enough additional low end to make the songs sound more modern and fun. For example, Paul McCartney's Pipes of Peace, Sade's Diamond Life, and The Housemartins' London 0 Hull 4. These albums can sound dull and boring on IEMs like Tin Audio T2 and even the KZ ZSN. Don't get me wrong - the T2 and ZSN are awesome IEMs, but this is a perfect example of why I like having different gear for different genres. It really makes a huge difference in listening enjoyment.
3. I also noticed some micro details in the bass, that I usually only notice in full size headphones (not IEMs):
- In Dirty Work by Steely Dan, I can actually feel a subtle vibration/pressure from the kick drum reverberating, like if my head was very close to the kick drum.
- In Michael Jackson's Rock With You, I can feel the same subtle pressure effect from the snare drums and even from the finger snaps.
- In Michael Jackson's Don't Stop Till You Get Enough, I can feel the bass guitar strings vibrating. Again, very subtle but it's there.
At 1st I assumed this was simply due to the EP10's v shape tune. But I tested the same tracks back-to-back against some other v shaped IEMs and the effect was not the same. Very cool
4. I do feel that the EP10 tuning has noticeably cleaner mids and tighter bass when amped. When played directly from my iPhone SE and unamped, it sounds somewhat mushier (like there is a thin layer of glue or honey smeared on the drum heads).
5. Mids can be recessed (more noticeable on some tracks vs others). For example, on Michael Jackson's Thriller, the background guitar that comes in at 0:28 is buried to the point that it's barely noticeable
6. The chin slider is useless. I'm glad the EP10 even has one, but it's too large to be effective, and slides back down after a while. If it continues to bother me, I may give it a whack with a flathead screwdriver (or a gentle pinch with some end nipper wire dikes) to shape it more into a figure 8 and making it tighter.
Have any of the other EP10 owners noticed any of these things?
