The beautiful Astell&Kern AK Zero earphones are made to provide the best in hybrid technology. Much like the car industry, hybrid technology has become the go-to platform for many earphone manufacturers of late. Astell & Kern have decided to introduce the stunning AK Zero1 earphones which benefit from 3 different driver technologies, each having their own benefits for specific frequency ranges. For the amazingly clear and accurate treble a micro planar driver has been used, which integrates beautifully with the dual balanced armature drivers that look after all of the midrange goodness. To provide the listener with incredible visceral bass response there is also an integrated 5.6mm dynamic driver, providing punch and power to the bass frequencies. The Zero1 has been acoustically matched to the Astell & Kern range of portable players.

The gorgeous design of the earphone has been shaped in order to offer incredible comfort for prolonged listening sessions, with the distinct design making the earphone a beautiful work of art that fits snuggly within the ear.

Three types of drivers

The AK ZERO1’s driver system 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.

Micro marvel

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.

Expert crossover

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

Best connection

MMCX connectors ensure a prime-quality connection between the ear housing and cable, offering 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.


Included in the package is an ultra-high quality cable to connect up to your favourite Astell & Kern player, with a silver-coated OFC copper cable. The cable for the Zero1 makes it exceptionally revealing with an amazing sound that envelops you in your favourite music.
