Intro…

It has been quite some time since I listened to a Tanchjim set of IEMs, since 2022 to be exact. The models I tried back then we probably more to my preference than to that of many others, due to a quite tame low end (except for the Tanya, which was quite elevated in the mid bass), and I found the performance at their respective price points to be a positive.

The 4U is a set that comes 2 years later but still aims at the reasonably priced category, available for just under 65€, featuring what they call a DMT-4 Ultra LCP Diaphragm dynamic driver.

What is a little different on this set is that they feature a 4-way dial that lets you choose between 4 different tunings, or rather 4 different bass levels, something that I will mention under the sound section.

Presentation…

Not much has changed since the last set I reviewed as far as packaging and contents. The outer white sleeve shows an image of the IEM on the front, with FR graphs and specifications on the back. This slides away to reveal a grey interior box with the Tanchjim logo on the top, almost identical to that of the Ola that I reviewed over 2 years ago. That is not a negative, the packaging is simple and elegant, so I am not complaining.

Opening the box reveals a sheet of anime stickers of a character named Asano, although I have no idea who it is, nor have I investigated 😉 Inside the box we get the IEMs, 6 sets of silicone tips (3 sizes of two types, large and small core), the cable, a small screwdriver to adjust the tuning selector and a small drawstring bag.

Again, almost identical to the contents of the Ola (except for the screwdriver and the stickers).

Build and construction…

The IEM construction also stands out to me as Tanchjim, even though it is a different shape to other models from the brand. It is a metal construction, using matte aluminium shells along with a shiny faceplate that sports the Tanchjim logo.

The shape I find is comfortable, they are fairly lightweight and they seem to be well built, something that I feel is the case with all Tanchjim products, at least those that I have seen.

The included cable is a simple lightweight 2 core braid that splits into individuals at the metal splitter. All the hardware is metal and matches the matte aluminium finish of the IEMs.

The rest of the contents are basically those that were included with the Ola, which is not to say that they are bad. They are not great but acceptable.

Sound…

When I first started listening to the 4U and playing with the tuning selector, the question that sprung to mind was “Why?”.

I understand that they want to give the users options, the same as other companies that include multiple nozzles or filters, and in this case, the fact that it is a dial that turns makes it a lot easier to change between tunings. However, the question of “Why?” Is more related to the tuning options they offer on this set.

As a picture is worth a thousand words (although I will probably still rack up a thousand words in this review), here is the graph of the 4 tuning options in relation to my usual reference:

As we move from FWD to UP to BCK to DWN, the tunings make less sense to me. I am actually quite fond of the FWD tuning, which I will comment on in just a moment, but the other tunings just give me the same sensation as losing a seal, with the bass just dropping off more and more as we go.

Now, you probably all know that I am not a fan of overly emphasized bass, as you can see from my preference target, although there are many sets with more bass than my preference and I still find to be great. In this case, I am quite happy with the presentation of these IEMs in the FWD position but I can’t say that I would choose to use them in any of the other modes. That doesn’t mean other people won’t, just that, for me personally, the FWD tuning would have been plenty.

So, starting off with the subbass, you can probably already guess that there isn’t a huge amount of rumble going on with this set. If you are someone who likes a deep rumbling bass, then these are not the choice for you, even in FWD mode.

However, where they do perform well is in the clarity and presentation of the midbass. I find them to lend themselves more to acoustical performances than electronic based music, with things like the bass on “No Sanctuary Here” being a little tame for those that seek a hard hitting low range. Again, that doesn’t mean it does it badly, the bass is there in quality, just not in quantity.

“Crazy” is pretty well balanced in the low ranges, with the reverb not being an issue as far being bloated or overly boomy. There is plenty of clarity and it fills in the low end of the rack nicely but without being the focus at any point. There is a little emphasis on Daniela’s voice in this track but it is clear and not harsh or too spicy, something that I am pleased to hear.

Listening to “Hotel California (acoustic)”, I would say that the guitar could do with just a little more body and warmth, but it is once again clear and nicely defined. With “Elephants On Ice Skates”, there is more focus on the plucks of the bass than on the low notes, yet the low notes are still there, the track doesn’t come across as “empty”, just a different presentation to that of so many other sets lately.

“Seven Nation Army” by Zella Day does seem to have a little more warmth in the body of the guitar but once again, the focus is shifted more towards the vocals. I actually find female vocals to be very enjoyable on the 4U, with them taking the centre of the stage but without becoming overly present or thin. They also deal fairly well with sibilance. There is still sibilance in the intro of “Hope Is A Dangerous Thing” but I find “Code Cool” to be slightly tamed in this regard, at least in comparison to what I would expect from this kind of tuning.

I find the upper mids to be smooth and enjoyable which moves into upper ranges that are not the smoothest but are certainly not a negative on this set, again, taking into consideration the tuning that the 4U are going for. There do seem to be some peaks that try to increase the sensation of detail, which is a shame because they can give a slight hint of being artificial at times.

The stage width is not huge but there is enough space for things to spread out a little, like the vocal layers of “Strange Fruit”, which are easily identifiable, although the main voice is slightly overpowering to the background vocals on occasions. With “La Luna”, the location of the instrument has space between them but they are not placed far away and the rear left guitar does seem to be more left than rear, but once more, not bad.

Conclusion…

It has actually been refreshing to listen to something that is a break from the majority of tunings lately, that seem to be aiming more for a warm and laid back signature. In the case of the Tanchjim 4U, it goes for a brighter more up front signature. There is more emphasis on vocals, especially female vocals, but they don’t become overly harsh or thin sounding.

I still have the same question though… why? I really don’t feel that the 4U needed that those extra positions that we get from the tuning selector. I could maybe understand positions 1 and 2, but I feel that 3 and 4 are unnecessary. In fact, I don’t think that even position 2 is necessary as those that are looking for this kind of signature will already enjoy the basic “FWD” position.

I think that if that tuning selector had been omitted, then maybe these IEMs would have dropped under the 50€ mark that I consider ultra budget and they would have been an easy budget recommendation for those looking for a tuning of this kind.

I am not saying that these are expensive, they are only 65€, and they are certainly a step forwards from the Ola, I just think that we are getting something that wasn’t really necessary. They aimed for a specific tuning and performance and got it, why add more bits that become redundant?
