TANCHJIM has not been on the IEM scene for too long and therefore still has a manageable IEM selection. Nevertheless, they seem to know their craft very well and already made us happy with the (MR. HARMAN) OXYGEN, or the small but fine BLUES.

The HANA seems to be a descendant of the OXYGEN with a new driver and adapted tuning, but even if they have sonic similarities, this can't be said in such a general way.


Everything we get from the OXYGEN, we also get from the HANA. However, the HANA looks as if it came directly from a fashion boutique. White and gold are certainly a noble combination, but plain is something else and one inevitably has the feeling that the HANA is not only addressed to the female population in its name (sorry for gendering, I don't care about that and I put everything into my ear as long as it sounds good!), because in addition there is a white (jewelry) hardcase in leather look and a 2-pin cable, which of course also shines in the "color combination".
Actually quite chic and homogeneous, but also a bit thickly applied.
The cable has a wonderful feel and makes a filigree but robust impression.

The elegant appearance of the HANA is of course also continued in the materials used (metal housing) and in the workmanship. There is nothing to criticize here and the Hana is very comfortable and safe to wear despite its weight.

However, a small point of criticism here, as with every TANCHJIM-IEM, is the isolation, which is rather average.


What does the HANA have in common with the OXYGEN? Well, if you compare the graphs, you might think it's the same driver, where you just forgot the filter, which attenuates the frequencies beyond 1kHz and reduces the peaks in the upper range, because up to this point, at least on paper, both IEMs are very similar. It's not quite as simple as that, because the drivers are made of different materials and differ slightly in their specifications. Nevertheless, you can clearly hear that this is a TANCHJIM product, even if you had the opportunity to hear the OXYGEN before.

In the end, I could use the OXYGEN again for the bass. I actually don't really hear any difference as long as I don't have to imagine it. Of course, this is where the subjective listening impression comes into play, because the HANA is tuned a bit brighter and the new driver has the better technical features, so the HANA sounds a bit cooler and more generous in comparison, which makes the bass sound a bit tighter and punchier for my taste, as long as you listen to music with it that serves the whole frequency spectrum in a balanced way. But if you listen to beats or bass-heavy music with it, it is very difficult to distinguish between the two IEMs in this range. Here I think I can hear slightly more level in the sub-bass of the Hana. So we get a very controlled, homogeneous and natural bass that doesn't feel attracted to the extreme or the subtle, but can develop pressure if it has to!

Due to the elevations in the upper mids and highs (similar to the BLUES) the HANA is a bit different from the HARMAN curve and the OXYGEN. For me this gives a welcome directness and clarity in the mids, which brings out the vocals more strongly and ensures a sharper separation and liveliness. At the same time, the HANA loses some of its naturalness and boasts a crisp, technical sound rather than musicality. Don't get me wrong, the HANA is not at all a shot in the dark in the mids, or too artificial, but here I like it a bit more puristic, without the "beauty" mobile phone photo filter with a bright blue sky and juicy green. Here it might sound a bit softer and more organic. I know I sometimes contradict myself here, for example when I wish for more assertiveness with the OXYGEN, but I wish for more relaxation with the HANA. Somewhere in the middle lies my happiness. Nevertheless, the Hana is sometimes too technical/analytical for me, just like the BLUES, but they are still bursting with quality and energy, which is fun, with a slight tendency to cross borders.

In the higher frequencies the HANA approaches the OXYGEN again. Clear, transparent, detailed and open, with a pleasant extension without overdoing it. The sibilants are more carried along than with the OXYGEN and from time to time it gets a bit more intense. For me it's just within limits, because they keep highs very clean and resolve even better than on the OXYGEN, without becoming artifacts. They have a bit more emphasis and sound a bit more lively, but for some people they can be too much of a good thing. They are also not micro-detail monsters.

What is there not to worry about with TANCHJIM? Right, the stage. Open, wide, deep and sorted. The separation is wonderful and we get an out-of-head experience, but it never sounds lost. Great!


The HANA is not a saving variant of the OXYGEN, as it is the case for example with the STARFIELD in relation to the KXXS. Despite the common sound characteristics the HANA is not automatically recommended if you like the OXYGEN. You should have a distinctive tolerance for pushed upper mids, where the Oxygen, or generally the HARMAN curve already has not too little of it. In addition one should of course like the bright tuning and enjoy technical details rather than leaning back and relax. For me the HANA is a very good IEM, which inspires me again and again with its clarity, voice presence and open stage. Every now and then I have to turn down the volume to keep the mids under control. Overall the OXYGEN is the more mature and natural IEM.

Thanks to OARDIO for the review unit.



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.
