Ok. Just got my ED10. I`ll make it shortly...
OOTB (with smallest black tips), ED10 are very good and definitely in top 3 of KZ latest IEM`s. Imo, by SQ, best after modified ATE, followed by ED9(brass) and ANV.
Now, this will be littlebit unfair since I have modified ATE but I`m going to be objective as I can.
ED10 vs. modded(m) ATE-b:
* ED10 has
littlebit more sub-bass
* ED10 has
littlebit V-shaped sound signature
* mATE-b has
littlebit better mids and thus more natural vocals and more dynamic sound
* ED10 soundstage is very good and I would say on par with mATE-b but latter has
littlebit better separation and transparency (result of modification)
* mATE-b has
littlebit better microdetails through FR including highs (result of modification). Maybe except sub-bass because ED10 has more quantity on it.
* mATE-b has
littlebit better balanced/neutral and natural sound signature
As You noted, I underlined word
littlebit because difference is quite small.
Source gear used to compare was hardware/firmware modified iBasso DX50 which has very neutral and detailed open sound with slight hint of warmth (naturality). For more details about source gear check profile.
I was expecting much more V-shaped signature from comments I have read from here.
I think they are actually quite source dependent, thus some users have different result with these.
So, in conclusion, I would say ED10 is a
must have in KZ lineup. Personally I rate KZ IEM`s as following:
1) mATE-b
2) ED10
3) ED9 (brass+foam)
4) ANV (only gripe with this IEM is little lack of sub-bass, otherwise would put it on 2nd/3rd place)
Hope it helps someone
