Unboxing & First Impressions
Kiwi Ears maintains a minimalist and functional approach to packaging, and the Airoso is no exception. The box design is clean and professional, featuring an illustration of the IEMs along with basic specifications.
Inside the Box
- Kiwi Ears Airoso IEMs
- Detachable 3.5mm cable
- Branded hard case for protection
- Three sets of ear tips
- User manual and warranty card
The redesigned hard case provides more space for travel, though the included cable is basic. Users seeking a premium wireless audio experiencemay prefer upgrading to a higher-quality cable.
Design & Build Quality
The Airoso features a resin and CNC-machined aluminum/titanium alloy construction, striking a balance between lightweight comfort and durability. The resin shell provides a smooth, ergonomic fit, while the metal faceplate adds a touch of premium aesthetics. One notable design feature is the ventilation system, which ensures pressure relief inside the ear for a more natural and comfortable listening experience. This also helps reduce unwanted driver flex.
With its lightweight body (12g per earbud) and ergonomic design, the Airoso sits snugly in the ear without causing discomfort. The angled nozzle and medium-sized shell ensure a secure fit, though users with smaller ears may need to experiment with various ear tips to achieve an optimal seal. Overall, this IEM offers an excellent combination of comfort and isolation, making it well-suited for extended listening sessions.
The Airoso features a detachable cable design, offering users the flexibility to upgrade or replace the cable as needed. This customization option ensures compatibility with a wide range of audio equipment and allows users to tailor their audio setup to personal preferences. Equipped with 2-pin connectors for secure and seamless connectivity, and a 1.2-meter cable length that provides sufficient reach for both stationary and portable use, the Airoso appeals to audiophiles who prioritize versatility and long-term usability.
However, based on user experience, the included stock cable is a drawback. While functional, it tends to tangle easily and lacks the premium feel expected at this level. That said, the fact that the cable is detachable is a definite advantage — it allows users to easily upgrade to a higher-quality balanced cable, which enhances handling and durability.
Sound Performance
The Kiwi Ears Airoso features a five-driver hybrid setup, including a dynamic driver (LCP + PU diaphragm) for deep, punchy bass and four balanced armature drivers for detailed mids and highs. Precision Crossover Technology ensures seamless frequency blending, resulting in a well-balanced and engaging sound signature.
- Bass (Low Frequencies): The Airoso delivers deep, controlled bass that enhances the listening experience without overwhelming the mids. The sub-bass extends well, providing a satisfying rumble on tracks like Hunter by Björk, while the mid-bass offers a defined thump, giving drums and bass guitars a natural presence. However, bass heads might find the quantity a bit restrained compared to some V-shaped IEMs.
- Mids (Mid Frequencies): The Airoso excels in midrange clarity, making vocals sound forward and well-articulated—ideal for vocal-centric music. Male vocals carry a warm, natural tone, while female vocals benefit from a slightly boosted upper midrange, adding airiness and extension. Instruments like acoustic guitars and pianos have a rich, organic timbre.
- Treble (High Frequencies): Crisp, airy, and well-extended, Airoso's treble brings out fine details without harshness or sibilance, even on bright recordings. Cymbals, hi-hats, and strings sound natural and textured, making it an excellent choice for jazz, classical, and acoustic genres. The treble also enhances the IEM's spacious soundstage, creating an open and immersive experience.
Based on extensive user impressions and listening sessions, the Kiwi Ears Airoso is widely regarded as one of the most musically satisfying in-ear monitors (IEMs) within its price range. Listeners consistently note its lush and balanced tuning, with a sound signature that caters to a broad range of genres.
The bass has been praised for its depth and texture, delivering a full-bodied response that is controlled rather than overwhelming. Vocals, especially in acoustic and jazz tracks, are described as warm, natural, and well-articulated. The treble is detailed yet smooth, offering clarity without introducing fatigue or harshness.
One of the most appreciated aspects of the Airoso is its effortless and cohesive presentation. Users highlight the high-quality sound that feels refined and highly musical. Complex tracks are handled with ease, and the IEM remains lively and engaging whether used for energetic electronic music or more intimate acoustic performances.
Overall, the Kiwi Ears Airoso has earned a strong reputation among audiophiles and casual listeners alike for its thoughtful tuning, technical performance, and enjoyable listening experience.
Soundstage & Imaging
One of Airoso's standout features is its wide and spacious soundstage. The sound extends beyond the ears, creating an immersive experience that rivals higher-end IEMs. Imaging is precise, allowing listeners to pinpoint the location of instruments within a mix. This makes the Airoso particularly enjoyable for live recordings and orchestral pieces.
Technical Performance
- Impedance: 18Ω
- Sensitivity: 110dB SPL/mW
- Frequency Response: 20Hz – 20kHz
- Connector Type: 3.5mm TRS (detachable)
With an 18Ω impedance and high sensitivity, the Airoso is easy to drive, making it compatible with most smartphones, digital audio players (DAPs), and DAC/AMPs. For best performance, pairing the Airoso with a dedicated DAC/AMP like the Fosi Audio K7 or Creative SoundBlaster X 5 enhances its dynamics and detail retrieval.
Conclusion
The Kiwi Ears Airoso stands out as a well-balanced and versatile IEM, offering a detailed and immersive listening experience. Its five-driver hybrid setup delivers deep, controlled bass, rich and natural mids, and airy, well-extended treble. The spacious soundstage and precise imaging enhance the overall experience, making it ideal for a variety of genres, from vocal-centric tracks to orchestral compositions.
Beyond sound quality, the Airoso excels in comfort and build. Its lightweight yet durable construction, ergonomic fit, and pressure-relief ventilation system make it highly suitable for long listening sessions. The detachable cable design adds flexibility, allowing users to easily upgrade to a higher-quality cable that can further enhance both usability and sound performance.
Still, for around $130, the Airoso delivers performance that exceeds expectations for its price point. If you're after a well-balanced, musical sound with just the right amount of fun—and don't mind investing in a better cable — it's absolutely worth considering.
With refined tuning, premium craftsmanship, and easy drivability, the Kiwi Ears Airoso is a top choice for audiophiles and casual listeners alike. It offers a high-fidelity experience at a competitive price, making it one of the best in-ear monitors for audiophiles in its class.
