disclaimer:
I'm fairly new to the audiophile world so some expectations might be unreasonable / too high
My expectations:
highly extended treble without (or hardly any) sibilances, probably also a bit of nice sparkle, no piercing or uneasiness both for young and older listeners - thus highly detailed yet enjoyable (over longer times) listening
mids are important for a more holistic experience (found that out with the TIN HIFI T2) due to the often existing v-curves on IEMs putting mids/voices in the background rather than in the center (right in the middle), a balanced and nicely detailed "sound environment" that feels coherent and natural (but also can be use for analysis).
I'm curious how the layering, separation, depth, etc. will be in practice
earphones that I finally can also hear on more louder volumes (due to the mentioned "Custom Air Hole" and the great tuning) without pain, ringing or fatigue for longer periods of time (and in the longer term saving my precious hearing capability, which I'm dependent on in my profession)
My vision (for the long term ? or already the HE100):
that the dynamic driver technology can more and more catch up towards planar driver technology - quicker movement without the disadvantages of planar tech (better bass)
I don't have the ES100 right now but it looks very interesting in case I switch away from LG-based Android smartphones (currently owner of LG V30)
Keep up the great work !
Looking forward to either test & review the HE100 myself or reading & watching the reviews
