BLON BL05

I was a little bias, because these had the name "Blon" in them, and it made me want to think that these were an upgrade to the 03's, and they're not, with that, they should have called them by another name.
After listening to them some more and putting away my bias, I decided to dress them up and start from scratch, something I should have done from the beginning. Tips(SpinFit CP100), Cable(TRN T3 Cable 2.5 silver 8 core), using a FiiO K3 Dac/amp.
They're somewhat balanced(not neutral), bass isn't a heavy hitter, but it's not without, and can reach deep but in a nice way, not impeding too much on the mids, I find that there is some treble roll off, but this makes the iem a little smoother sounding, granted there is an upper mid range boost but seems to have settled down after using them for awhile, still don't know about that burn in thing, if it's the mind or if its actually settling down, but they have settled in, and it's to the better this time around.
For a single DD, they have a nice wide 360 soundstage, good layering, mids are nice but these are not detail beast, but there is detail, vocals are still upfront, maybe a touch too much but lately I've been finding this to appeal to me, as long as it isn't shouty, and as I said, they've settled in.
Overall, they've become a nice relax pair to listen with for long periods, balanced for the most part, nothing really seems to be dominating anymore.

The blon 05 has better quantity and quality of the bass compare to t4, but against to blon 03, the 03 has more powerful, warm, thickness on the bass.
The 05 bass can go more deeper than 03.

The blon 03 has most mid bass( which can be bloated) body follow by 05 and t4.
The 05 has most upper mids boost(which make it shouty and vocal sound too thin) follow by t4 then 03

The treble on 03 does the best jobs for me, as the treble on the 05 and t4 are too bright(but it bring kind of detail and space feel)

Sound stage 05~03 > t4
Details 05~t4( through treble boost)~03
Imagine 03~05>t4
Separation 03~05>t4

Overall the tonality on blon 03 is my favorite, it has good low end, creamy and smooth mids, great treble, as the 05 are too shouty on upper mids and thin vocal make it not my cup of tea( it is even shouty and thin vocal compare to t4), and for t4, it is good, but too neutral, boring for me.

I will be getting he t2 plus soon , I think for under 60 usd dollar, the blon 03 will be my choice, and t4 is good, but for me bring, for blon 05, I think the tin t2plus will be really similar to that, with more better upper mids and treble.

compared to Tin T4,

Pros : Blon05 has better soundstage and powerful sound
Cons : eartip must be replaced, mid and high sounds dry than T4

for $40 price It is OK ,
If you could make it sounds more smoother , It could be used as all arounder,

This is not an upgrade to the 03's, it's a whole new different tuning signature, not warm, nor bright, balanced with a slight bass elevation, and a rolled off treble, and mids do have some detail, but there's no weight in them, making it a truly boring set for me. But if you're into something like the Tin HiFi T2's, this might be up your alley way.
