HISENIOR is certainly not yet known to many, at least outside Asia. Among other things, this description of the company can be found on their website:

"The Brand Hisenior combined by two words "Hifi" "Senior", which means every Hisenior In-ear monitor is masterfully tuned and carefully customized.".

Admittedly not very creative, but I take the professional claim from them. It is also reflected in their IEM offers, where attention is paid to assign a theme or a musical use (drummer, singer, guitarist etc.) to each IEM and to match it with the underlying idea. In addition, many models are available as universal or custom versions.

The T2(U) is the first in their line-up and is comparatively cheap, considering that you can also get it as a custom (T2) for 20 € more.It is a well-balanced all-rounder that does its job very satisfactorily, without the really big ambitions.


The T2(U) is cast in resin and makes a professionally manufactured impression. The fit is very ergonomic and offers a very good comfort.

As for the accessories, I was surprised by the waterproof transport box, the adapter to 2.5mm and the large number of foam and silicone tips. This is really more than I expected. Only what I should do with the glasses cleaning cloth is not quite clear to me yet, because a fingerprint magnet is the T2(U) certainly not, but better to have than to need. Even though I am not allowed to make great demands anymore, the cable is just average. But if a 16-core cable with silver/copper mixture had been included here, I would doubt whether the company would make any money at all.

Because of the ergonomic and closed design, the T2(U) isolates passively very well. With running music one then isolates oneself almost completely from the outside world.


The T2U is certainly not an IEM that inspires you right at the first note. It is more of an IEM that you can rely on in a variety of applications without expecting miracles from it. Solid, mature, mellow and detailed.

The CI-22955 from Knowles is a popular BA driver for the bass because it already has good technical features. However, it is also important to find a way to implement the driver well and to tune it with others. The 22955 is characterized by a punchy and quite firm bass, but where you have to rein in the upper bass and generally keep him a bit on the leash so that he doesn't drown out the signature too much. The T2U does that quite well, but the bass could be a bit more crisp and structured. This is where the driver itself comes to its limits at some point, and so the best is almost done out of it, resulting in a firm and warm bass foundation without pushing itself too much into the foreground. In the subrange, however, something is still missing and sometimes it is a bit too grumpy, especially in low male voices.

I would describe the T2U as warm and neutral with clean, clear mids that are only slightly influenced by the bass. One could assume they are a bit lifeless, but I find them quite natural and mellow. Here and there I would like to see a bit more steam, but I also appreciate them for their linearity and also intimacy. Vocals have a good weight and a realistic timbre, but without sparking with energy or developing a great dynamic. Emotions are therefore rather less built up.

The highs are on a par with the bass and mids. They don't have the greatest extension and a slight sibilant emphasis. Otherwise they are pleasant to listen to, but without that certain extra. Certainly an advantage for the stage and the audibility, but not to analyze every detail down to the bone marrow. Good, although not outstanding, which underlines the extremely solid overall impression of the T2U and gives a coherent sound image.

You can't expect an all too wide stage with expansive dimensions in all directions from the T2U. It has a pleasing scale, but focuses more on intimacy. Nevertheless, the imaging within the created space is quite precise and three-dimensional. Here, too, the word "solid", which is positively meant in this context, is appropriate.


The T2U is a really good and balanced IEM, which can also meet professional requirements. Of course it is interesting that the T2U is also available as a custom version (T2) for about 20 € more and therefore it can be an inexpensive introduction to professional in-ear monitoring on stage. It doesn't have any area that really stands out positively, but it's solid and a good tool for consuming or analyzing music, with some slight drawbacks, whether in the bass, midrange or high frequencies. Nevertheless, he convinces me over the whole range with his minimalistic approach. An IEM, where you know what you get. Solid all-rounder!



Here the processing plays a role and the usability of the scope of supply. Additionally the appearance, wearing comfort and robustness.

Here I evaluate for me subjectively the price/performance ratio - does not flow into the evaluation!

Z: No Brainer

A: money well spent

B: all right, you can do

C: gives better for less money

D: overpriced

E: collector's price

Daily life:
Here, I focus on the long-term audibility and whether I can hear it well out of the box. This is of course very subjective and therefore only a minimal deduction or bonus.
