BS AUDIO. I find the name a bit daring if you don't know its meaning and I assume that this is the case for the majority of potential buyers, at least outside China.
No it is not for Bullsh** but for "Brainstorm". Figures, doesn't it? :D

The SUPER ONE is an interesting single dynamic IEM, which has fallen for the MOONDROP KXXS in design and doesn't seem to be averse to the HARMAN curve. Okay, that they stick to the mainstream curve is their right and also a good idea, but these "light" design déjà-vus from the land of the rising sun don't have to be approved of all the time, although they didn't have to look that far over the edge of the earth's disk to do so, but only wait until the moon drops.


Actually it is enough to look at the picture of the Super ONE and you know what phase is. Polished metal with a well-known bend in the look. BS AUDIO jumps on the MOONDROP hype train with the design, but without copying one to one. The SUPER ONE is more angular and not quite as filigree (if you can say that about the KXXS). Nevertheless the housing seems indestructible, but not clumsy.

I can't judge whether the accessories incl. the IEM are delivered in the meantime, or even in a proper packaging, because I received the SUPER ONE together with a good 4-core silver-plated copper cable and 3 pairs of silicone tips in a plastic bag (well packed in air foil of course). The silicone tips take some getting used to, because somehow they are cut quite strangely and feel interesting, but seal excellently.
The isolation is okay in this context, but you can still see the environment well, which can be positive for one person, negative for another. But with music you are as good as sealed off.

Whoever is well-disposed towards the STARFIELD or KXXS in terms of comfort is also well-disposed towards the SUPER ONE. I personally have nothing to complain about.


The tuning of the SUPER ONE is based on TANCHJIM and MOONDROP's single dynamic IEMs, which like to use brighter Harman-sounds with pushed upper mids and also attach importance to an appealing transparency and stage.

The bass is quite smooth, with a fun punch and a decent sub bass extension, but doesn't quite reach the quality of an OXYGEN or HANA. It's mostly controlled, but sometimes it's a bit too soft on the road and a bit too verbose for me, but still quite authentic and detailed. He doesn't quite knock me off my feet, because I miss the firmness for that and he also doesn't always act precisely, but he sounds natural and doesn't overdo it.

The bass doesn't leave the mids virginal, but doesn't use them shamelessly either. The mids are pleasantly warm and have body. They don't let themselves be forced and counter with clarity and assertiveness. They are soft and relaxed in the lower range, but unfortunately become a bit forward towards the top, which makes the SUPER ONE an IEM that is better enjoyed at moderate volume, no matter how well you like the song. Vocals are nicely highlighted, which you are positively used to by the typical harman peak between 2 and 3 kHz, but get a bit too much presence by another 5 kHz peak, which makes them sound a bit unpleasant sometimes. This can be controlled quite well with the volume control, but the driver tends to exaggerate a bit here. So spare your hearing a bit and the mids will pay you back!

The highs, on the other hand, are again as soft as butter with a natural sound reproduction without reaching the very high peaks. I always find this quite pleasant with the HARMAN signature, even if it seldom has an analytical claim, but can still score with airiness and transparency without being exaggerated. This also applies to the SUPER ONE.
Of course, the technical ace in the driver's sleeve also plays a role here, of which the SUPER ONE doesn't have many, but is very pleasing and a good team player.

I really like the stage, which is neither too intimate nor too wide. It could be better, but with a Budget IEM you should also keep your feet on the ground a bit. I like the 3D image, within which I find the instrument separation just as successful.


Is the SUPER ONE now super? It's good and to be honest I can't really blame him too much if he doesn't come out as a screamer every now and then.
But there are also songs where I raise my eyebrows and think: "WOW", it's not only good but really good and memories of the KPE or OXYGEN come back.
Add to that the seemingly indestructible case and certainly the nice looking optics.

I can definitely recommend the SUPER ONE if you like HARMAN, a focus on voices and details in all frequency ranges. In addition the SUPER ONE can act mostly relaxed and an equalizer would give you a really good IEM for little money. But my evaluations are not based on mods or a 31-band EQ, but on Out-Of-The-Box. Nevertheless I would like to mention the potential!




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.
