Specially Tuned By Campfire Audio For Astell&Kern

SOLARIS, Campfire Audio's high-end earphones that are highly acclaimed by audiophiles around the globe, are now reborn in collaboration with Astell&Kern.

AK SOLARIS X is a culmination of Campfire Audio's technology.
Its hybrid system, which integrates a balanced BA driver and an optimized dynamic driver, faithfully conveys Astell&Kern's deep and rich sound.

Internal Structure
The custom BA driver designed specifically for the AK SOLARIS X is smaller in size than its predecessor used in existing models, and offers wideband performance.
Coupled with Campfire’s patented tuned acoustic expansion chamber (T.A.E.C.) technology, the new driver also offers smooth and extended high frequencies.
Another BA driver provides rich delivery of the mid-range frequencies, and the custom 10mm dynamic driver optimized for the Polarity Tuned Chamber reproduces deeper and more refined mid-to-low frequency.
Each earphone integrates a 3D Printed Acoustic Chamber to enable the drivers to deliver the highest audio quality possible, creating a natural and accurate sound.

4N Pure Silver Litz Cable
AK SOLARIS X comes with a balanced 2.5mm pure silver cable allowing the earphones to reach their full performance potential. Pure Silver Litz Cable is produced with four 4N (99.99% purity) conductors to offer clearer, extended sounds.
The jacket that wraps around each conductor ensures both flexibility and durability. At the same time, it is soft to touch and a practical to use every day.

Tuned Acoustic Expansion Chamber
The tuned acoustic expansion chamber technology delivers extended high frequencies without sibilance or fatigue. The driver performance has been optimized by adjusting the volume of space available in front of the driver. This is superior to the typical “Tube+Dampener” system because it provides a direct passage from the driver to your ear, which results in unsurpassed clarity and extension.

Polarity Tuned Chamber
3D printed acoustic tuning for dynamic drivers
The Polarity Tuned Chamber optimizes the sonic performance of the dynamic drivers. Deploying particular volume cavities, both in front of and behind the dynamic driver, bigger sounds can be pulled from smaller drivers.

3D Printed Interior
Carefully Designed for Optimum Sonic Performance
Solaris features an acoustically optimized interior model that allows each driver to deliver the very best sound quality. When heard together, the drivers offer a seamless musical experience as a result of this process.

Beryllium / Copper MMCX Connections
The Astell & Kern beryllium/copper MMCX connectors are more resilient against wear and tear than regular brass connectors.

Handcrafted IEM Made in the USA
AK SOLARIS X is hand-assembled in Portland, Oregon, USA by skilled craftsmen, ensuring each individual earphone is manufactured to the highest quality standards.

Eco-Friendly Cork Case
Our cork case is handmade with eco-friendly materials for long-lasting durability while maintaining its original shape. The owner of the company wanted to create a place where people with disabilities can have a job and gain the power to stand on their own. To achieve this goal, he is working side-by-side with people who are physically disabled in a small boutique shop that he founded in Portugal.
