The energetic frontier woman
>> 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! <<
