Comfort, design and construction:
The faceplate goes for a very distinctive aesthetic, with a combination of dark and reddish tones that give it an aggressive appearance which I personally think fits the name of the product very well and, above all, its character. It is not a set that seeks to go unnoticed and I understand that it may appeal more or less depending on each person’s tastes, but I have to admit that the final result seems quite successful to me.
As for the construction, I think Punch Audio has done a good job. The shells are made of resin and have a uniform finish, without burrs, imperfections or joints that particularly draw attention. To the touch they convey a fairly good sense of solidity and, although we are not dealing with a metal body, at no point did I have the feeling that I was looking at a fragile or poorly made product.
As for ergonomics, here I have to make a small warning. These are large monitors and those with small ears should take this into account. In my case, I had no major problems achieving a stable fit, although I wouldn’t say that these are IEMs that completely disappear inside the ear. Their presence can be felt and it may be necessary to slightly search for the correct position so that the points of contact are properly distributed.
Once I found the appropriate eartip size, the fit seemed firm and secure to me. During my prolonged listening sessions I did not experience pain or particularly annoying pressure points, although I would not place them among the most comfortable monitors I have tried. The included eartips do their job correctly, providing a good seal from the first moment, although I consider it worthwhile to experiment with other options until finding the one that best adapts to our ear canal.
The cable seems like another one of the strong points to me. It is thick and robust, conveying a fairly good sense of quality to the touch. It is not the lightest cable I have used and it can feel somewhat bulky for those who prefer thin cables for situations involving more movement, but in my experience I had no major problems with tangles or pulls.

-Stock silicone eartips.
-Stock 4.4mm cable.
Sound signature:
To focus this analysis of the Martilo on the prominence and dominance of its bass region, I think, would be to oversimplify the set’s proposal, although I have more than enough desire to praise this characteristic.
Its soul is quite simple to interpret: to offer a clearly warm and V-shaped response, where the lower region takes on enormous prominence, but while trying to preserve enough cleanliness, resolution and organization so that the set does not end up becoming a simple bass-producing machine.
Starting with the lower region, the sub-bass has simply spectacular extension. Its depth is easily palpable and appears with an authority that we rarely find in this segment. There is a very evident sensation of physical pressure, especially with electronic music, hip-hop or any recording where the lowest frequencies have enough prominence.
As a curious fact and something I did not expect, the sub-bass does not end up becoming a completely uncontrolled mass. I always perceived a fairly convincing sense of cleanliness and the notes maintain good definition. These monitors achieve precisely what I consider the most difficult thing with this type of tuning: offering an amount of bass that could seem excessive on paper without immediately giving us the feeling that everything else has been buried underneath it.
The mid-bass performs spectacularly under my criteria, although here we find an even more evident impact. The impact is forceful, physical and with a fairly convincing texture. The kick drum has an extraordinary presence with a body that can be especially addictive in certain genres. I do not consider it a dry or particularly fast bass, but neither do I find such a prolonged decay that it generates a constant sensation of slowness and poor transparency.
And this is where one of the main virtues of this Punch Audio model lies. The tuning does not try to hide the amount of bass; on the contrary, it turns it into the main argument, but it maintains enough control for the response to preserve a certain structure. It is a warm, large and enveloping bass, with a clearly superior physicality to what is usual, but one that does not need to completely sacrifice definition to achieve it.
Even so, I do not think it would be fair to present this behavior as perfect. In particularly dense recordings or those with a large accumulation of instruments in the lower region, the Martilo can convey a certain sense of congestion.
The transition into the midrange is carried out in a fairly progressive manner. The bleed coming from the bass exists, but it is sufficiently controlled so that the tonality does not end up becoming ridiculously muddy. The instruments show generous note weight and a certain warmth that fits perfectly with the overall philosophy of the set.
This is not a monitor that intends to offer particularly transparent or prominent mids. The instrumentation appears slightly behind the lower region and this makes the Martilo have a clearly more fun than analytical presentation. However, we also do not find any worrying loss of information. The resolution is sufficient to easily follow the different instrumental lines and the timbre maintains fairly convincing naturalness.
Male vocals enjoy considerable body. The combination between the mid-bass and the note weight generates a fairly full presentation, with good articulation and a sensation of physical presence that especially benefits deeper voices. They are not the protagonists of the scene, but neither are they completely buried behind the bass.
Female vocals, on the other hand, receive somewhat more clarity and openness. They retain good articulation and appear with enough presence so that the tonality does not end up becoming excessively dark. Even so, those looking for an especially vocal-focused IEM will probably find more appropriate options. The Martilo does not want to place vocals in the foreground; it wants them to form part of a large, energetic and enveloping presentation.
As for the highest frequencies, we probably find the area that most clearly reveals the philosophy of this set. Extension is correct and there is enough information to avoid a completely dull sensation, but the energy is quite restrained. The Martilo does not produce a sensation of artificial sparkle to increase the perception of detail and this has a very positive consequence: listening remains very comfortable even after several hours.
This decision also has its negative side. Lovers of more incisive tunings will probably miss some more air and presence in the upper region. Micro-information does not appear as easily as it does in other sets more oriented toward analysis and certain small details can remain slightly behind the main instrumentation.
Detail retrieval is therefore quite good considering the philosophy of the tuning. We are not dealing with a monitor that dissects every recording nor with a tool especially suited to discovering all the small details of a mix. However, the information appears in a sufficiently natural way and the overall cleanliness allows us to enjoy complex recordings without having to constantly make an analytical effort.
The overall dynamics also left me with good impressions. The transients retain enough speed so that the set does not end up sounding excessively heavy and the notes disappear with reasonable agility. This is especially important considering the amount of energy present in the lower region, because a slower response would have turned the Martilo into a much more difficult monitor to enjoy with certain genres.
Separation is another aspect that I find particularly interesting. Considering that we are dealing with a clearly basshead set, I expected a greater loss of organization, but the Martilo manages to maintain a fairly logical structure between the different sound planes. The different instrumental lines can be followed with ease and the stereo image maintains convincing precision.
The soundstage conveys fairly generous width. I would not say that it is an artificially huge stage, but there is a sensation of width and depth that complements the physical presentation of the bass very well. The result is a fairly enveloping stage, where certain elements can appear clearly differentiated in front of and behind the central position.
When the mix becomes especially complex, however, this is where some of its limitations appear. The Martilo can maintain a good level of organization in most situations, but recordings with an extreme amount of sound layers end up showing that we are not dealing with a monitor designed exclusively for technical dissection. Some elements lose a little of their separation and the stage can feel somewhat more compressed.

If during the music analysis I already commented that reducing the Martilo solely to its enormous amount of bass would be to oversimplify its proposal, in single-player video games this characteristic becomes precisely its greatest strength. The response of these monitors manages to build a large, physical and tremendously spectacular presentation, making action scenes take on a dimension that few sets manage to convey so easily.
In moments of greatest intensity, where explosions, collapses, gunshots or other large effects occupy the scene, the Martilo feels completely in its element. The extension of the sub-bass is simply spectacular and provides a sensation of depth and physical pressure that makes every explosion have a truly convincing impact. The mid-bass completes this experience with a forceful punch, making hits and impacts acquire extraordinary body. The Martilo makes you feel all of this really strongly.
Dialogues also receive a fairly convincing presentation. Male voices enjoy considerable body, while female voices provide somewhat more clarity and openness. They are not particularly prominent within the scene, but at no point did I have difficulty following conversations or understanding the narrative even when the action increased considerably in intensity.
Where I consider the Martilo to stand out once again is in environmental recreation. The scene conveys fairly generous width and the separation allows details such as wind, echoes, water or the movement of vegetation to be appreciated. The enormous sense of scale provided by the bass also works in its favor, making certain environments convey a truly convincing sense of space.
Technically, it continues to leave good impressions. The stereo image is precise and positioning makes it easy to interpret the surrounding space correctly. The separation between effects, music and dialogue maintains a satisfactory level even when many sound layers come together.

If there is a scenario where the Punch Audio Martilo shows a different side from the one offered in music and single-player video games, it is precisely in competitive titles. Its enormous presence in the lower region, which previously was so spectacular, does not play as clearly in its favor here. We are not dealing with a bad IEM for competing in this type of game, but neither do I consider its tuning to be the most appropriate when we need to extract every last detail from the soundscape.
In Counter-Strike 2, footsteps, reloads and utilities appear correctly defined and the stereo image makes it fairly easy to interpret the direction of opponents. The problem appears when the bass becomes prominent, as it can take some attention away from certain secondary sounds. Distance is also fairly convincing, although other more balanced and brighter sets make it somewhat easier to read distant sounds.
In Apex Legends, where verticality and the enormous amount of simultaneous effects considerably complicate interpretation, the Martilo maintains fairly good organization. Abilities, gunshots and movements remain sufficiently separated during a good part of the match, although the amount of energy in the lower end can make the moments of greatest load somewhat more difficult to interpret. It does not become a serious problem, but it does require somewhat more attention.
In Call of Duty: Warzone it once again shows a fairly similar situation. Explosions, killstreaks and gunshots acquire considerable spectacularity thanks to that very physical bass, but precisely that energy can end up competing with footsteps, reloads or nearby movements. Fortunately, the good control prevents everything from turning into a completely muddy mass and the important information remains accessible.
Finally, Battlefield 6 is probably where its limitations become most apparent. The enormous amount of vehicles, explosions, gunshots and destruction puts the Martilo’s separation capabilities to the test and, although it manages to maintain a fairly reasonable order, I would not say that it is a competitive prodigy. The image remains precise and the positioning sufficiently convincing, but other IEMs with a response that is less loaded in the bass make this type of soundscape easier to read.
Final conclusion and personal evaluations:
Having reached this point, I think the Punch Audio Martilo is a monitor that is difficult to judge solely from a technical perspective. Its proposal is tremendously clear and without a split personality: to offer a warm, huge and physical response, where the bass takes on extraordinary prominence, but without completely giving up cleanliness, separation and resolution. And I consider that it achieves this with considerable competence.
What has surprised me the most is precisely its ability to control such a quantity of energy. The sub-bass is spectacular and the mid-bass provides a forceful and addictive punch, but I rarely had the sensation of being faced with a completely uncontrolled set. There is some congestion when the mix becomes especially dense, and the mids and highs do not seek prominence, but they form part of a coherent and tremendously enjoyable presentation.
It is a monitor that manages to convey scale, body and physicality with extraordinary ease, while its wide stage and good separation provide enough organization so that all that energy does not end up becoming tiring.
Ultimately, the Martilo seems to me to be a very particular proposal and, above all, a very fun one, and although its limitations appear when we seek maximum transparency or dissection, I consider that its ability to offer such an impact without completely losing control is, under my criteria, its greatest virtue.
