• 𝕊𝕦𝕓-𝕓𝕒𝕤𝕤: It is not extremely deep, but it is firm, it adds a feeling of ephemeral envelopment and convincing width, but without muddying the other ranges.

• 𝔹𝕒𝕤𝕤: Powerful and with good fast punch, it provides pleasant and technical impact, adding rhythm without saturating due to its agile decay.

• 𝕃𝕠𝕨 𝕞𝕚𝕕𝕤: Recessed, but with enough weight to support the base of instruments. They are not tremendously textured.

• 𝕄𝕚𝕕𝕤: Slightly back, but clear and defined, they do not dominate the mix since they prefer not to be the protagonists. Even so, their presence is pleasant.

• 𝕌𝕡𝕡𝕖𝕣 𝕞𝕚𝕕𝕤: Boosted and crisp, they give clarity to the instrumentation and provide a sufficient amount of detail, adding presence without losing definition.

• 𝕋𝕣𝕖𝕓𝕝𝕖: Correct extension and bright, they add air and resolution to the sounds, although they can become tiring if you are very exposed to tracks with these characteristics or are sensitive.

• 𝕍𝕠𝕔𝕒𝕝𝕤: Deep male voices are perceived with body, but somewhat far away and thin, mid male voices are clear and female voices stand out for brightness and detail, standing out in the mix without losing clarity.

• 𝕊𝕠𝕦𝕟𝕕𝕤𝕥𝕒𝕘𝕖: Spacious and open, with good lateral perception and good depth. It caught my attention before any other characteristic.

• 𝕀𝕞𝕒𝕘𝕚𝕟𝕘: Precise and defined, it allows sounds to be located easily within the space. Very accurate and intelligent.

• 𝕃𝕒𝕪𝕖𝕣𝕚𝕟𝕘: Layers correctly separated; in complex scenes it can feel a bit saturated but I do not think more can be demanded for this price.

• 𝔻𝕖𝕥𝕒𝕚𝕝 𝕣𝕖𝕥𝕣𝕚𝕖𝕧𝕒𝕝: Really high, it reveals nuances and textures in treble and transients, making small details perceptible.

Always seeking the most cinematic experience possible, testing narrative and action-intensive titles. Check my blog to see the specific games and the conditions of audio analysis in video games. Source used FiiO K11 with filter No. 5 (neutral) and mid gain.

• 𝔸𝕔𝕥𝕚𝕠𝕟: Explosions and gunshots feel powerful, but not very enveloping, with bass that hits fast and highlights each impact, but without an overwhelming rumble that favors adrenaline-charged moments.

• 𝔻𝕚𝕒𝕝𝕠𝕘𝕦𝕖𝕤: Clear and distinguishable voices, although with a bright touch that makes them stand out more than natural.

• 𝕀𝕞𝕞𝕖𝕣𝕤𝕚𝕠𝕟: Environmental sounds and minor effects are captured easily, creating a sense of a living world, full of layers, but without reaching a cozy feeling, rather a cold one.

• 𝕃𝕒𝕪𝕖𝕣 𝕤𝕖𝕡𝕒𝕣𝕒𝕥𝕚𝕠𝕟: Music, voices and effects keep some distance between them. It is easy to identify each element even in not too complex moments.

• 𝕊𝕥𝕒𝕘𝕖: Wide and enveloping, it helps to perceive large and detailed environments within the game. An experience that turned out to be quite above its competition sector.

• 𝕊𝕚𝕓𝕚𝕝𝕒𝕟𝕔𝕖: It is noticeable in intense high-frequency sounds, and can be somewhat incisive. Careful here: lower the volume.

• ℙ𝕠𝕤𝕚𝕥𝕚𝕠𝕟𝕚𝕟𝕘: Clear directionality; sounds are located precisely, making it easier to follow the action. Static sound elements satisfactorily revealed their position.

The video games used to draw these conclusions were: 𝑪𝒐𝒖𝒏𝒕𝒆𝒓 𝑺𝒕𝒓𝒊𝒌𝒆 2, 𝑨𝒑𝒆𝒙 𝑳𝒆𝒈𝒆𝒏𝒅𝒔, 𝑪𝒂𝒍𝒍 𝒐𝒇 𝑫𝒖𝒕𝒚 𝑾𝒂𝒓𝒛𝒐𝒏𝒆 𝒂𝒏𝒅 𝑩𝒂𝒕𝒕𝒍𝒆𝒇𝒊𝒆𝒍𝒅 6. The source used was Fiio K11 with filter No. 5 (neutral) and mid gain.

• ℂ𝕠𝕦𝕟𝕥𝕖𝕣 𝕊𝕥𝕣𝕚𝕜𝕖 𝟚: Enemy footsteps are very clear, even on noisy surfaces, and gunshots are placed with great three-dimensional precision. Thanks to layer separation, weapons and reloads can be distinguished from sounds produced by allies or enemies, both near and far, allowing you to anticipate positions and plan your tactics. The treble boost helps detect movements at a distance without losing the impact of nearby explosions.

• 𝔸𝕡𝕖𝕩 𝕃𝕖𝕘𝕖𝕟𝕕𝕤: The wide and detailed soundstage allows you to locate mobile enemies and teammates easily. The effects of abilities, shields and gunshots stand out without masking stealthy footsteps behind obstacles or at height. This facilitates tactical decision-making and strategic positioning in chaotic combat.

• ℂ𝕒𝕝𝕝 𝕠𝕗 𝔻𝕦𝕥𝕪 𝕎𝕒𝕣𝕫𝕠𝕟𝕖: The conditions of this KZ highlight important gunshots and explosions while keeping footsteps and minor noises perceptible, crucial for detecting hidden enemies. Spatial coherence and precise positioning allow you to calculate distances and directions quickly, obtaining a really superior experience to react to surprise attacks or changes in cover.

• 𝔹𝕒𝕥𝕥𝕝𝕖𝕗𝕚𝕖𝕝𝕕 𝟞: On large and open maps, vehicles, distant gunshots and explosions and enemy movements are clearly perceived. Layer separation and directional definition allow you to mentally organize the information of the environment, facilitating defensive and offensive strategies, and maximizing the advantage in combat at any scale of depth or laterality.

𝐙𝐒𝟏𝟐 𝐏𝐫𝐨 𝟐 is a monitor with a fast character and good energy at both ends. Particularly, for my personal tastes, it is somewhat far from my preferences: a more marked presence in the sub-bass and mids in a more forward position would have made it a more refined product, especially for electronic music.

Nevertheless, in my favorite genres, such as 𝑪𝒍𝒂𝒔𝒔𝒊𝒄 𝑹𝒐𝒄𝒌, 𝑴𝒆𝒕𝒂𝒍 𝒐𝒓 𝑵𝒖-𝑴𝒆𝒕𝒂𝒍, 𝑰 𝒐𝒃𝒕𝒂𝒊𝒏𝒆𝒅 𝒂 𝒇𝒂𝒏𝒕𝒂𝒔𝒕𝒊𝒄 𝒆𝒙𝒑𝒆𝒓𝒊𝒆𝒏𝒄𝒆, where I only needed more presence of voices in sung tracks and it never stopped showing very gratifying technical capabilities in terms of stage, positioning and details.

As for 𝒗𝒊𝒅𝒆𝒐 𝒈𝒂𝒎𝒆𝒔, in single player, it would not be an IEM that I would use, it lacks body in the sub-bass to impress or in very dense scenes I evidenced a lack of clarity, as well as somewhat recessed dialogues.

As for 𝒄𝒐𝒎𝒑𝒆𝒕𝒊𝒕𝒊𝒗𝒆 𝒗𝒊𝒅𝒆𝒐 𝒈𝒂𝒎𝒆𝒔, I think they perform very well, being a great option due to the excellent three-dimensionality when representing the stage and the almost perfect placement of every sound element that is happening.



𝑹𝒆𝒄𝒐𝒎𝒎𝒆𝒏𝒅𝒆𝒅 𝒇𝒐𝒓: rhythmic instrumental tracks and/or with little or no vocal presence, competitive online video games.

𝑵𝒐𝒕 𝒓𝒆𝒄𝒐𝒎𝒎𝒆𝒏𝒅𝒆𝒅 𝒇𝒐𝒓: vocal tracks, classical, electronic and single-player video games where you need powerful effects or have a large amount of dialogue.

This set of monitors has been sent by 𝐊𝐞𝐞𝐩𝐇𝐢𝐟𝐢. I sincerely appreciate the opportunity to be able to test one of their products at no cost and that no conditions were imposed when making this analysis.

Despite this, my priority is to be as impartial as possible within the subjectivity that analyzing an audio product entails. My opinion belongs only to me and I develop it around the perception of my ears. If you have a different one, it is just as valid. Please feel free to share it.
