Hello friends, i'm new here in head-fi and I'm from Brazil, I'm using Google translator to write this review in English, so I ask you to forgive any mistakes you find.
I come here to bring my impressions about the in ear from hisenior audio, the T4 acquired by me at the end of November on Aliexpress and received in February of this year.
The Hisenior T4 is an IEM with 4 Knowles balanced armatures, with a choice of its UIEM and CustomIEM versions (you send your impression of the ear canal to the seller and he manufactures the molded earpiece to your ear), which has numerous customizable options To meet the aesthetic preferences of each one. The Hisenior T4 has a 4-way crossover and 3 distinct sound "holes" for the low, medium and high frequency outputs and uses the Knowles CI-22955 for the bass, the Knowles CI series is "known" for its use for low frequencies in EMI. The medium and high frequencies are handled by Knowles ED-29689 (who do a fantastic job in this region) and Knowles TWFK-30017 (double BA, the smallest double BA in the world).
The iem comes in a waterproof case, the unboxing experience is not "exciting" but if you are like me this is not what matters, but the sound.
Well here we are dealing with a $ 240 in ear (depends on the configuration that choosing the ciem costs more) mine was the universal version with two-pin fitting (you also pay a little more for the two pins).
You choose between several types of shell and faceplate available in the ad (some different ones have a value charged outside).
Remember that the signature can be "personalized" when contacting the seller. Yes, the handset is handmade, the seller knows a lot about the subject and this was simply the best shopping experience I have ever had, it is no wonder that he has almost 100% positive reviews.
As for the tips, there are many options (as you can see in the photos) I believe it will not be difficult to find one that offers a good seal.
As for my preferences for sound, I told him to have a considerable amount of bass because I came from a headset with the **** h5 that used the same Knowles ci 22955 that really didn't have the bass that I would like and I was afraid to get this new phone because of that and the same told me to be calm about this issue.
It is worth remembering that because it is made by hand and until the signature is customizable to your preferences, the seller asks for a time to manufacture and adjust the signature for about 10 days.
Build quality
We have an excellent job, I asked for that specific color but the seller didn't have real photos of the phone with this color option, but depending on which one to choose it will send you real photos taken from a smartphone.
The cable that came to me is an upgrade cable, which is very good, it feels solid and malleable in the right measure (different from the **** h5 cable which was hard and did not return to its original shape)
It has no steep corners, everything is rounded and with a perfect fit of the front panel with the phone body, the phone body is filled with resin which makes the phone solid.
Comfort and isolation
Well here is a strong point, its solid body provides excellent insulation, and very good comfort. The earphone never presses directly on the ear regardless of the tip I use, but it also leaves no space that impairs the isolation (as in the zsx for example). It is not a big phone, there is not much difference in size for the **** h5 or kinera idun for example.
Stage and image.
The stage is deeper than wide, there is no sensation of unwanted extension that leaves a wide and false sound stage, but devoid of presence. The images are fantastic and the vocal and instrument placement is also great. The panning motion from left to right is noticeable, but not so focused.
Low
Here we separate the men from the boys. As I said before about my conversation with Garrett from his senior about the bass, when listening to this earphone even without warming up the feeling was wooh here in there is even a ci 22955? It is just fantastic the bass produced by this phone, both in quantity and speed, texture and extension of the subwoofer (of course it does not have as much extension as the kz zsx for example) but it has the same depth as the sub and quantity of the attack bass (100hz ) of CCA C10 for example without that tremendous hole in the midfielders that we will talk about later.
And it has more extension in the subwoofer and a lot more bass in general than the kinera idun for example which is a phone that I like a lot too and is a hybrid phone with 1dd of 7mm pro bass and 2ba from knowles too (of course more series cheaper than those in t4)
Medium
Here again it was a victory, which are those produced by Knowles ED-29689.
And look, I came from a **** h5 that is a reference in medium.
The midfielders here have a good weight, male voices have a good vibration very naturally, without ever seeming to resonate, instruments that work in this range are very apparent and clear.
The female voices are presented in front but without that feeling of incomplete because the in ear has a reproduction too thin.
Treble
Here we have a clean and impeccable reproduction, which leaves the hearing in great detail without any type of fatigue.
The sound of the cymbals and the simbal on this phone is divine, you feel it from beginning to end of each ring without bothering you with time
The treble has a good amount of air without looking "artificial"
Far from simplicity and fatigue, I can hear this phone for hours and it was without tiring.
Conclusion
It is also worth mentioning that this phone needs a DAP (digital audio player) or at least a dogle DAC in the cell phone, not because of the need for "power" but because an ordinary cell phone or PC cannot show what this phone has to offer and it's a waste.
My dap is for entry, it is a m0 shanling that costs around 100 dollar
I don't have any other headphones in this price range and in fact from what I found on it I don't even need it.
You may be asking yourself: but no negative points?
The answer is no, this is how a in ear should sound. This is a phone for all types of music and all tastes.
