So, I have about 20hrs use on the T800 so far..
I've been running quite a few sound tests as well.
One test of note: I was able to hear/feel a 14Hz Sine wave.
14hz is REALLY LOW!
Nothing else I own can do that.
However, "usable sub-bass" on the T00 doesn't come in till around 35Hz...
The T800 does bass quite well!
Bass is rather quick, but -
slightly- slower than typical BAs.
It's gets quite intense on EDM tracks, and is just about right on "bass lite" Classic Rock tracks.
Unfortunately, I do not like certain aspects of the T800's signature...
It has that typical 2khz-4khz boosted "ChiFi signature".
Sadly, Cable/Tip swapping are just not enough to correct this either.
Oddly enough I have found that it's 3.5khz peak doesn't bother me nearly as much as it's 2khz peak..
I ran several sine waves through the T800 at very low (near inaudible) volumes, and the one tone that I could hear far above anything else was 2khz.
Once I get the Knowles filters in, I'm sure I'll be more content with the sound.
It seems like the "white 680 Ohm" filters should work perfectly for me.
For now: It's nothing a little EQ can't fix.
Here is my currant favorite all around EQ setting for the T800:
Now keep in mind, this EQ curve is based on:
Tips: Comply Audio Pro (wax guard)
Cable: NICHCK High Purity Copper 16 core.
Source: Sabaj Da3
Player: Foobar2000 + 31 Band EQ addon
EQ settings are slightly different (of course) with my LG V20/Neutron Player and my old Ibasso DX50.
Now, just so you don't think I'm EQing the schit out of these; there is really nothing that adds/subtracts more than 2db within my above posted curve.
On brighter tracks, I will occasionally pull the 2khz down to 3db, even 4.5db.
As you can see the 2khz's neighboring frequencies, are also slightly reduced.
The Mid Bass is also very slightly pulled out.
The Mids are very slightly boosted as well..
Nothing above/below 1.7db though.
This EQ curve brings the T800 very close to neutral reference signature, with slightly boosted bass (just how I like it!).
Soundstage:
Soundstage tests were conducted using:
"The Ultimate Headphone Demonstration Disc"
Stage is really good on the T800, but my ToneKing T4 is better honestly.
The T800 is a bit wider than the T4 but not as much Height & Depth as the T4.
The T800's stage stays on the far outside left/right of your ears,
But does not extend above the upper back part of your head..
So, it's like you are listening to a concert with your back facing the stage...
Sounds never seems to get onto the top front or even center of your head.
With the ToneKing T4 (same: tips/cables/sources) I can get center stage sounds onto the upper top of my forehead!
The T4 is a pretty amazing IEM for below $200.
I HIGHLY recommend the ToneKing T4 for stage and mid-range (as long as you are willing to use some Sub-Bass EQ, and maybe a little treble reduction for some folks).
I have tried several tips/cables/sources on the T800 and I can't seem to improve the stage much beyond what it already is.
However, the T800 beats the T4 hands down in Bass response and overall micro-details.
The T800 goes into "Nano-Detail" territory!
And with mild EQ (and possibly Knowles Filters) the T800 can have an very good signature that I can be quite satisfied with.
The T800 does what it does, quite well!
I have been hearing nano-details that I have never heard with any headphone or IEM..
For that matter; even my $5k Q12 studio monitors can't reproduce this kind of detail.
So yeah, the micro detail on the T800 is quite impeccable!
All in all, I'd say it's a nice quality IEM for a $300.
However, I really wish it had a lower mid-treble peak, along with 25% more stage -depth- (width is great!)...
Okay, that's it for now...
Once I get my filters in I'll post some final thoughts.
