Enjoy premium sound reproduction with the Astell & Kern AK ZERO2, a pair of advanced Quad-brid in-ear monitors that's build off the success of the original ZERO1 IEMs. Several enhancements have been added, including an ultra-refined crossover network design and acoustic chamber that perfectly harmonizes the four integrated driver types.

The AK ZERO2 features four drivers including a micro rectangular planar dynamic driver, two dual custom balanced armature drivers, and a 10mm dynamic driver with a piezoelectric transducer, which combine in a 3D printed acoustic chamber. The outer enclosure is crafted from a precision CNC-machined aluminum housing, which limits resonance to create a stable, high-quality sound. The ZERO2 includes two cables (4.4mm TRRRS and 3.5mm TRS) made from Hi-Fi-grade pure silver-coated OFC. A set of five silicone eartips, a pair of foam eartips, and a travel case are included.

• Four different types of drivers
• Perfectly harmonized driver structure
• Highest crossover network management
• Acoustic chamber by 3D print technology
• Precise CNC metal housing
• Hi-Fi grade pure silver-coated OFC cable
• Made in Japan

Special Micro Rectangular Planar Dynamic Driver

• High—crisp and dynamic treble sound
• The micro rectangular planar dynamic driver is specifically developed to deliver high frequencies, featuring advanced technology that allows a planar driver to be used in IEMs, despite the extreme difficulty in making it small enough to fit in such a small cavity. A&K selected a light yet sturdy planar membrane to minimize frequency loss and applied a trembler with a thin metal membrane and polymer film to create lifelike vivid high frequencies. This provides a clear and dynamic high-frequency response.

Dual Custom Balanced Armature Drivers

• Mid-Low—transparent vocal sound
• Full Range—perfectly balanced and rich sound
• The Coil Parameter Dual Custom BA Driver is a custom-made driver designed to reproduce both full-range and mid- to low-range frequencies. It comes with a total of four drivers: two BA drivers that offer ultralow distortion to create clear low- to mid-ranged vocal sounds and two BA drivers that offer perfectly balanced rich sounds, uniquely tuned to harmonize each frequency range, playing perfect sounds.

Single 10mm Dynamic Driver with Piezoelectric Transducer

• Low & Super High—the deepest bass and clear treble sound
• Various types of carefully designed drivers create rich, Hi-Fi sounds. The 10mm dynamic driver used in the AK ZERO2 is meticulously manufactured using a fully automated process. This allows the driver to recreate rich and deep low frequencies. An additional piezoelectric transducer works in tandem with the dynamic driver, serving as a super tweeter that asserts its presence in the super-high frequency range that many IEMs struggle to recreate.

The ultrarefined crossover network enables a perfect balance between six drivers with distinctive sound characteristics, maximizing each of their acoustic traits while creating a balanced harmonized sound.

Each driver is placed optimally in an acoustic chamber that is created through refined 3D printing technology. This design eliminates any unnecessary movement and resonance of the drivers for permanently stable performance.

The housing, which is made using Astell & Kern's advanced aluminum processing technology, limits resonance to create stable high-quality sound.

• The pure silver-coated OFC cable, designed to maximize the performance of the AK ZERO2, is created with high-purity silver plating and copper, and adds a touch of style with plugs crafted from aluminum.
• The MMCX connectors offers a robust connection and a long-lasting and stable life cycle.

Each AK ZERO2 is meticulously assembled by professional technicians with extensive experience and is produced at A&K's state of the art facilities in Japan to offer you the highest quality through strictly managed processes.

Related Questions and Answers

Q: 1. What is the size of the slides that fit this device?

A: The Godox AK-R21 would use slides that are similar to a 35mm film strip. Those slides can be found here: https://bhpho.to/3IXREWu

Q: 2. Will this work with a soundcraft ui16? We have 4 aux sends (xlr) and want to have 4 independent channels that can each have its own mix.

A: Yes, the CAD GXLIEM4 Quad-Mix In-Ear Wireless Monitoring System will work well in a scenario where four independent auxiliary mixes are needed for in-ear monitoring. The auxiliary outputs of the Soundcraft Ui16 16-Input Remote-Controlled Digital Mixer would pair directly with the four inputs on the CAD GXLIEM4.

Q: 3. Is the magnetic ring included with this AK-R16 gel set product (not the AK-r17) please ?

A: Yes, the magnetic ring is included in the Godox AK-R16 Gel Set for Round Flash Head.

Q: 4. The CTO gels are pretty straightforward. But anyone know how strong the green gel is? Is it a half-green?

A: The Godox AK-R16 Gel Set for Round Flash Head does not have listed specifications for the green gel, there is no way to guarantee any specific color.

Q: 5. Does the case fit the DR-07X?

A: This accessory pack is designed for use with the Tascam DR-05X, DR-07X, DR-40X, DR-22WL, DR-44WL, DR-100MKIII, and previous DR Series handheld recorders.

Q: 6. How does battery charging work here?

A: The CAD GXLIEM2 Dual-Mix In-Ear Wireless Monitoring System uses AC power for the tranmitter, and the included CAD GXLIEMBP Bodypack Receiver uses two AA batteries for powering. AA batteries, if rechargeable, should have their own proprietary charger.

Q: 7. Can this be used for both the AK-R21 and the AK-1 modifiers?

A: No, the Godox AK-R25 Square Flash Head Adapter Holder is very specific and is only for the Godox AK-R21 Projection Attachment, https://bhpho.to/3FLhV7A .

Q: 8. What is the difference between the two diffusion filters that are included?

A: Godox does not list the exact difference in the two diffusions that come with the Godox AK-R16 Gel Set for Round Flash Head. Just that the one is stronger than the other. So, around 1/2 stop to Full stop diffusion.

Q: 9. Can custom slides be created?

A: No, the Godox Slide Kit for AK-R21 are a proprietary size. And you can not make others for it as of now.

Q: 10. Is this compatible with the Godox AD300 Pro?

A: This is not compatible with the Ad300Pro.
