The Dunu Kima 2 IEMs are a compelling choice for those who prioritize both build quality and sound refinement in their audio equipment. Designed with an external magnetic DLC composite diaphragm dynamic driver, these earphones manage to strike a fine balance between rich, textured audio performance and the robustness needed for daily use. Manufactured by Dongguan Dadian Electronics Co., Ltd., the Kima 2 showcases advanced engineering without overwhelming the listener with unnecessary complexity.
Build Quality and Materials
The Kima 2 features a sleek shell made from S316 stainless steel, providing a sturdy yet lightweight design that feels premium without adding undue bulk, weighing in at approximately 10.5 grams per side. This material choice not only ensures durability but also offers a sophisticated aesthetic. The earphones come with a modular cable system, featuring a four-core single-crystal copper and silver-plated OCC cable, which enhances both signal transmission and durability.
The 1.2m cable includes a 0.78mm 2-pin connector, allowing for easy cable swapping and customization. The Q-Lock Mini interchangeable plug system is the same found in the Titan S2 IEM, further increasing versatility, as it comes with both 3.5mm single-ended and 4.4mm balanced plugs, catering to a range of listening setups.
When it comes to audio performance, the Dunu Kima 2 offers an impressive frequency response of 5 Hz to 40 kHz, far exceeding the standard human hearing range. This ensures that even the most subtle nuances in music can be appreciated, while also delivering ample headroom for high-resolution audio.
With an impedance of 20Ω and a sensitivity of 108 dB/mW (@ 1 kHz), these IEMs are easily driven by most portable devices, but their true potential shines with more powerful sources, thanks to their compatibility with 4.4mm balanced output. The Kima 2 is rated for Total Harmonic Distortion (THD) of less than 0.3% at 1 kHz, ensuring minimal distortion even at higher volumes.
Bass, Mids, and Treble
In terms of sound signature, the Kima 2 excels in delivering a balanced, refined listening experience. The bass is tight, offering good texture and depth without overwhelming the mids or treble. Sub-bass performance is notably enhanced compared to previous models, providing a punchy, fuller sound that remains well-controlled. It manages to stay slightly north of neutral, giving listeners warmth in the lower frequencies without overshadowing the rest of the spectrum.
The mids are clean and natural, with vocals and instruments sounding clear and well-separated. Dunu has tuned the mids with a slight forwardness, ensuring that vocals come through without sounding shouty or overemphasized. This balance makes for a comfortable listening experience during long sessions, as the Kima 2 avoids fatigue commonly caused by excessive mid-range prominence.
The treble performance is another standout feature. The Kima 2 offers smooth treble reproduction, which is often difficult to achieve in single dynamic driver designs. This smoothness is paired with a touch of sparkle that adds air and openness to the sound, particularly noticeable in high-hats and cymbals. Despite this added clarity, the treble never becomes harsh or sibilant, making these IEMs ideal for listeners sensitive to high frequencies.
Accessories and Usability
One of the key strengths of the Kima 2 lies in its extensive accessory package, which feels well-considered and practical for users. Included in the box are four different types of ear tips, each in multiple sizes to ensure a comfortable and secure fit for a wide range of ears. The earphones also come with a sturdy case that’s large enough to accommodate not only the earphones but also a small dongle or DAC, making the Kima 2 ideal for on-the-go audiophiles. The modular cable system allows you to quickly swap between 3.5mm and 4.4mm plugs, adding another layer of versatility for different audio setups.
Additionally, Dunu provides small thoughtful touches, such as a cleaning brush to maintain the IEMs and a clip to secure the cable. While the included ear hooks are designed for comfort, the cable itself is robust, though some may find it slightly springy. The braided design ensures that the cable is durable and resistant to tangling, a common issue with lower-quality alternatives.
