This in-ear monitor (IEM) features three different types of drivers to deliver a ground-breaking hybrid sound. Composed of a micro planar dynamic driver, dual balanced armature (BA) drivers and a dynamic driver, this unique design combines the sonic characteristics of each driver to produce an unprecedented natural audio.

The Micro Rectangular Planar Dynamic Driver is a specially developed, highly advanced driver that allows a planar driver design, normally difficult to scale down for headphones, to be applied to in-ear monitors. Adopting a sturdy and lightweight planar membrane to minimise frequency loss, this is combined with a vibration panel boasting a high-polymer and thin metal film to create crystal clear and dynamic high frequencies.

The AK ZERO1’s driver system also features dual BA drivers, using custom-designed coils to deliver transparent vocals with super-low distortion. Couple this with the single 5.6 mm dynamic driver to ensure rich, controlled and deep low frequencies and the AK ZERO1 is poised to deliver its pioneering hybrid sound.

To realise this new sound through the ideal frequency response, a Crossover Network design was generated based on a thorough understanding of each driver’s parameters. Once established, each driver is carefully placed in the optimal position, enclosed in specifically designed acoustic chambers manufactured with 3D printing technology.

To further maximise the audio performance the AK ZERO1 arrives equipped with a pure silver-coated OFC cables. Exquisitely crafted with high-purity silver plating and copper, alongside aluminum plugs, this design strives to maintain transparency of the audio signal.

MMCX connectors ensure a prime-quality connection between the ear housing and cable, offering a long-lasting and stable performance. Elsewhere, the shape of the housing and the slender ear nozzles have been carefully designed and refined to not only provide a secure and comfortable fit, but to deliver the sound efficiently and accurately through your ears.
