Kiwi Ears Airoso

Manufacturer: Kiwi Ears

The Kiwi Ears Airoso is an in-ear monitor built around a hybrid 1DD + 4BA driver configuration, combining a dynamic driver with four balanced armature units within a 3D-printed resin shell. The earphones come packaged with a travel bag and use a detachable cable system, making them a practical option for everyday transport and use.

On the technical side, the Airoso houses a total of five drivers and operates at 18 ohms impedance, covering a frequency range of 20 Hz to 20,000 Hz. The included cable measures 1.2 meters in length, is made from oxygen-free copper, and terminates in a standard 3.5 mm connector, attaching to the earphones via a 2-Pin 0.78 mm socket. Neither an in-line control panel nor a built-in microphone is present.

Pros
  • The detachable cable allows for easy replacement or swapping without affecting the earphones themselves
  • A hybrid configuration of one dynamic driver and four balanced armature units covers a wide range of sonic responsibilities across the driver array
  • The 3D-printed resin shell enables a precise and consistent form factor for the housing
  • A travel bag is included, making it straightforward to store and carry the earphones safely
  • The oxygen-free copper cable connects via a standard 3.5 mm plug, ensuring broad compatibility with common audio sources
  • The 2-Pin 0.78 mm connector is a widely adopted standard, making cable replacement straightforward if needed
Cons
  • No in-line control panel is present, meaning playback and volume adjustments must be handled directly on the source device
  • The absence of a built-in microphone limits hands-free use for calls or voice input
  • The 3.5 mm termination requires an adapter when used with devices that lack a dedicated headphone jack
Who is this for?

The Airoso is well-suited for listeners who value a hybrid multi-driver setup and want a structured in-ear monitor experience across different genres or listening scenarios. Its detachable OFC cable with a standard 3.5 mm termination makes it a practical choice for users who prefer the flexibility to swap cables or connect directly to conventional audio players and DACs without additional adapters. The included travel bag also makes it a reasonable fit for those who commute or move between listening environments regularly.

Who is this NOT for?

This product is not well-suited for users who need hands-free calling or voice assistant access, as it lacks both a built-in microphone and an in-line control panel, making it impractical for those who rely on these features during daily use. It is also a poor match for listeners who primarily use devices without a 3.5 mm headphone output, such as many current smartphones, since no alternative termination is provided. Users looking for a fully wireless or cable-free experience will find the wired-only design incompatible with their preferences.

General info:

Has an in-line control panel ✕

The Kiwi Ears Airoso uses a hybrid 1DD + 4BA driver configuration, pairing a dynamic driver with four balanced armature units to handle sound reproduction. The shell is constructed from 3D-printed resin, keeping the build process precise and lightweight. A travel bag is included in the package, while an in-line control panel and a built-in microphone are not part of the design.

Specifications:

drivers count 5
impedance 18 Ohms
lowest frequency 20 Hz
highest frequency 20000 Hz

The Airoso is equipped with a total of 5 drivers and presents an impedance of 18 Ohms, which gives a general indication of how it interacts with the output impedance of a source device. Its specified frequency range spans from 20 Hz at the low end up to 20,000 Hz at the top, covering the full extent of the standard audible spectrum.

Cable:

Connector type 3.5 mm
Pin connector 2-Pin (0.78 mm)
Cable material Oxygen-free copper (OFC)
cable length 1.2 m
has a detachable cable ✓

The Airoso comes with a detachable cable made from oxygen-free copper (OFC), measuring 1.2 meters in length. It connects to the earphones through a 2-Pin 0.78 mm socket and terminates in a standard 3.5 mm plug at the source end.

Final Verdict

The Kiwi Ears Airoso presents a well-defined in-ear monitor built around a hybrid 1DD + 4BA five-driver configuration housed in a 3D-printed resin shell, offering a structured approach to driver arrangement within a portable form factor. Its detachable OFC cable, standard 3.5 mm termination, and included travel bag reflect a design oriented toward practical, everyday wired listening. The absence of a microphone and in-line controls does narrow its appeal to a more dedicated audio-focused audience, but for users seeking a capable wired IEM with replaceable cable support and broad source compatibility, the Airoso stands as a coherent and purposeful option within its category.
