The Kiwi Ears Airoso are wired hybrid in-ear monitors (IEMs) featuring a 1 dynamic driver + 4 balanced armature driver configuration, designed to deliver a precise, detailed and immersive listening experience in a lightweight and comfortable form factor. Thanks to Precision Crossover technology, combining physical and RC networks, the frequency response is smooth and well integrated across the entire spectrum, providing a balanced sound signature with reduced distortion and excellent clarity.
The premium construction combines a CNC-machined aluminum alloy and titanium faceplate with a 3D-printed resin shell, ensuring durability, light weight and long-lasting comfort for extended listening sessions. The detachable cable with 0.78mm CIEM connectors and a 3.5mm jack termination offers flexibility and customization, making the Airoso compatible with a wide range of portable and desktop audio equipment.
The Kiwi Ears Airoso rely on a carefully optimized hybrid acoustic architecture combining a custom dynamic driver with four balanced armature drivers. The dynamic driver features a composite LCP + PU diaphragm, selected for its rigidity, low mass and excellent damping properties, ensuring extremely low distortion and consistent performance at any listening level. This design delivers deep, fast and well-controlled bass while maintaining excellent midrange clarity.
The four balanced armature drivers complement this foundation with dedicated roles: two drivers handle the high frequencies, while the remaining two extend the response into the ultra-high range. This configuration enhances precision, instrument separation and micro-detail reproduction, resulting in an immersive, detailed and well-balanced soundstage across the entire frequency range.


The Airoso’s design clearly reflects its high-end positioning. The earphones combine a CNC-machined aluminum alloy and titanium faceplate, ensuring rigidity and refined finishing, with a 3D-printed resin shell offering high dimensional accuracy. This combination of materials results in a product that is both robust, durable and lightweight, perfectly suited for everyday use.
Special attention has also been given to ergonomics: the housing naturally conforms to the shape of the ear, providing a secure and comfortable fit even during long listening sessions. This design helps reduce both auditory and physical fatigue, making the Airoso an excellent choice for audiophiles seeking a balance between sound quality, long-lasting comfort and durability.
The Kiwi Ears Airoso are equipped with a detachable cable, offering genuine flexibility and improved long-term usability. The 0.78mm 2-pin connectors ensure a reliable connection and make it easy to replace or upgrade the cable as needed, whether for switching to a balanced cable or simply replacing a worn one.
The included cable, approximately 1.2m long, provides comfortable freedom of movement for both portable and desktop use. This modular design allows the Airoso to adapt easily to a wide variety of audio setups, meeting the expectations of demanding users who value versatility, customization and product longevity.
