Antlion, known for their high-quality ModMic microphone, which offered a solution for gamers seeking superior audio without compromising microphone quality by attaching to existing headphones, is again addressing a similar challenge. The increasing adoption of In-Ear Monitors (IEMs) among gamers has highlighted a need for integrated microphone solutions, as most IEMs lack this feature. Antlion’s response is the Kimura series, featuring a built-in microphone. Today, we evaluate the premium model, the Kimura Duo.
While extensive literature exists detailing the distinctions between IEMs and traditional in-ear headphones, it’s generally accepted that IEMs are positioned deeper within the ear canal and cater to users with heightened audio expectations, such as music producers. This demographic typically did not require integrated microphone solutions. However, the shift of gamers towards IEMs has created a demand for this functionality.
What is Kimura Duo?
The Antlion Kimura Duo is an IEM featuring a dual-driver configuration, with one driver dedicated to low frequencies and the other to high frequencies. It includes a two-meter MMCX cable, with the microphone integrated into the right earpiece’s arm. The cable terminates in separate 3.5mm connectors for the microphone and headphones, and an adapter is provided for devices with combined input/output jacks. The standardized, detachable connectors on both the cable and earphones allow for versatile use. The microphone can be paired with other IEMs, or the Kimura Duo can be used with an alternative cable to bypass the microphone, suitable for music listening. The included carrying case is of marginal quality and somewhat detracts from the overall premium feel. The package also contains three sizes of silicone ear tips and one memory foam tip to accommodate various ear shapes.
The In-Game Audio Experience
How does the Kimura Duo perform during gaming? As expected, the soundstage is narrower compared to traditional open-back headphones. However, relative to other IEMs like the ZSN Pro X, the soundstage is surprisingly expansive. The sound isolation is exceptional, to the point where the low battery alert from a nearby baby monitor was completely missed. One minor issue encountered was a slight vacuum-like sensation in the ears, which caused some discomfort after approximately one hour of use and could be almost painful when removing the IEMs too quickly. Positional audio was accurate and natural across a variety of tested games, quickly fostering immersion. The dedicated high-frequency driver proved beneficial, enhancing the clarity of opponent’s footsteps, particularly in PC games.
When connected to the controller of an Xbox Series S, the audio quality experienced a significant drop. The sound became noticeably inferior, exhibiting a closed-in and somewhat tinny characteristic. Increasing the volume improved the sound somewhat, but at the expense of comfort. Furthermore, the absence of a physical volume control on the headset proved to be a drawback. While volume adjustment is easily managed on PC, in-game volume control on the Xbox is not readily accessible.
General Audio Performance
The Kimura Duo delivers impressive audio across diverse music genres and games, with particular emphasis on bass reproduction. The bass is powerful and present, yet retains excellent speed and clarity; fast bass drum passages, for example, remain distinct. While the bass is not overly emphasized, it may not be considered entirely neutral and could be a matter of personal preference. High frequencies are clear and well-defined. The tuning appears tailored for gaming, with the prominent bass and clear treble lending themselves well to impactful explosions, sharp gunfire, and subtle footsteps.
Microphone Quality
The microphone exhibits good recording quality with no major shortcomings. However, it demonstrates high sensitivity, picking up ambient sounds within the recording environment. Users with loud, clicky keyboards intending to use the Kimura Duo for PC gaming should consider alternative solutions or utilize third-party noise-filtering software to mitigate distracting frequencies.
Conclusion: Kimura Duo
Does the Antlion Kimura Duo provide a viable solution for gamers seeking IEMs with integrated microphones, or does it fall short? It is a competent product catering to a specific niche: PC gamers who prefer IEMs and require a decent microphone, but who do not use particularly noisy keyboards. Given the price point and target application, the Kimura Duo is a worthwhile option despite its limitations. For casual gamers who value good sound quality and do not aspire to be streamers, this IEM is a recommendable solution.
