Sometimes, in the somewhat hectic and fast-paced ((C)HI-FI)-world, one should take a break and reflect on what you own and appreciate in search of faster, higher, better. If we break this down to the topic of in-ears, we are talking about two copies, which I have owned for more than half a year now, use daily, but haven't put my impressions on paper yet. Probably because I didn't think it was necessary by integrating it into my everyday life, or because I wanted to keep this treasure for myself. These are the IKKO OH10 and the TIN HIFI P1. Let's start here with the OH10, for me the perfect all-rounder with fun factor and sophistication.


2-pin cable, 6 pairs of silicone tips (vocal/balanced), leather case and cufflink. Sounds good? It is, but: the leather pouch is practically useless, at least not for in-ears, yet nice to look at and the cable is, carefully speaking, so lala. Up to the Y-split everything is still good, but then it becomes no longer appropriate to the purchase price. It does what it should, but if you compare the in-ears with their excellent workmanship and haptics with the cable, you wonder how it could have gotten lost in the box. It just doesn't make the valuable impression that is given by the in-ears themselves.

Well, the in-ear itself is not only visually well done despite its considerable weight. The wearing comfort is without criticism, but one should definitely use cables with ear stiffeners (provided with the included cable), because without them their center of gravity is too low, so that they could fall out of the ear, because the cable would not provide enough hold. The OH10 weighs almost twice as much as the OH1, which doesn't bother me personally, but certainly not everyone is that tolerant.

The isolation is the same as with the OH1: 1A! Jeez IKKO, why this CABLE!


Let's come to what has made the OKKO IH10 my daily companion and that is its uncompromising, dynamic and balanced sound.

Although the OH10 has a stronger V-signature than the OH1, it is more detailed and the mids are not as reduced as one might expect.

The bass is almost 1:1 similar to the OH1, but I would describe the bass of the OH10 as a bit softer and more balanced concerning sub and mid bass. It has noticeable depth and a nice dry punch. It doesn't have a bass head level, but I suspect that for purists it's already too much elevated. I don't count myself among them and am more than satisfied with the bass presentation of the OH10. It can really bang on electro, or hip-hop, but it can also hold back when not badly needed. This means that he can find exactly the right impact for the music in each case and always stays in control. Is there any criticism? Always: Although the bass can shine with texture, details and pleasant punch, it could be a bit tighter and really swing the hammer. The bass of the BGVP DMS, for example, has a better range.

Even though the OH1 has the more prominent mids compared to the OH10, they are even better for my taste with the OH10. They sound more defined and natural. The bass has no influence on the mids, since it also drops significantly in the upper bass, which mainly contributes to clarity and avoids boom. Vocals sound wonderfully natural and mellow, without exaggerated hardness or sharpness. No matter if man or woman, voices are always in the center of attention, but without jumping directly into the face or disappearing in the musical background. They could have a bit more body in some parts, but that's grumbling on a very high level. The mids are also very clear and transparent, probably the biggest plus here. No matter if guitars, saxophone or piano, everything sounds realistic and free of sealed nuances. The sibilants are well suppressed, but without having to accept any loss of content in the frequency range.

A further advance over the OH1 are the trebles. If I have criticized the stability of the trebles in multilayered music a bit, this is no longer the case with the OH10 as long as you keep the volume in mind. With too much level, the OH10 also reaches its limits, but only if you want to go to an ear, nose and throat specialist afterwards. The trebles are wonderfully airy, have a slightly larger extension compared to OH1 and bring a certain lightness to the way they present the music. Details are reproduced without any problems and even in the very high range a level increase provides clarity and brilliance. There is really little to criticize here. If you want to take a very critical view, you could wish for a bit more energy in the high frequencies.

The stage of the OH10 is remarkable. In width and depth, a spacious 3D image is created, so that you partly have your hands full with sorting and locating all the small details, which is meant positively. Because an amazing amount happens and you can still find a new detail in some corner during the 3rd song repeat if you concentrate on it. Sounds good? It is, but wait for the P1 ;)


The OH10 easily made it into my in-ear heart, even though I had some starting problems with it at first. This was because, for example, with the BGVP DMG, I had a very hard, punchy mid-bass treble monster (positive) for the most part in my ears. So the hearing needs a short time to get used to it. I am writing this only so that the OH10 is not written off right after the first hearing impression. I appeal to give it some time and you will not regret it! It rewards you with a detailed, warm, balanced V/W signature and will never give you problems with the sound, no matter what genre. Compared to the OH1, there are small but useful improvements towards balance, with some loss of liveliness. If you already have the OH1, you don't have to upgrade to the OH10 and are afraid to miss something. Who has no IKKO experience yet: ... take the plunge!




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.
