Astell&Kern Layla AION In-Ear Monitor Headset
Jerry Harvey Audio is the creator of the world's leading custom in-ear monitor headphones created in collaboration with Astell & Kern.
When combined with Layla AION IEMs and Astell & Kern player, they let you listen to music the way a recording artist and Mix Engineer wanted to hear it. 
The first Layla was released as a custom headset in 2014 and instantly became a milestone in the audiophile world. Since then, Layla has been released in limited editions in two variants, the "Carbon Fiber Edition" and the "Full Metal Jacket". Each generation has taken the market by surprise as the industry's first full Carbon Fiber headset and then the first full Titanium headset. The newest and third generation is the most exciting: Layla AION. 
AION represents the past, present and future achievements of Jerry Harvey Audio. We took the original Layla sound signature and combined it with our constantly evolving, industry-leading manufacturing processes, latest patent technologies and designs to make the new Layla AION the best and most advanced headphone available.
Layla AION Technology 
Powered by SoundrIVe™
12 drivers per headphone capsule: Quad Low, Quad Mid and Quad High Proprietary Balanced Fixtures.
Sonic Tube Chassis ™
The 3D-printed chambers accommodate 12 driver configurations and apply frectase technology – allowing for a smaller shell design without affecting sound quality.
freqPhase™
The patented technology ensures the correct phase and time balance of all frequencies, providing the most accurate music reproduction of any headphones available.
Acoustic Sound Room ™
The recessed tubing keeps sweat away and reduces the need for excessive cleaning.
Machined Carbon Fiber Shell
Every Layla AION starts out as a carbon fiber block created by compressing hundreds of resin-infused carbon fiber fabrics. After an initial machining process and then a secondary hand shaping, Layla AION is precisely adjusted and hand-assembled using state-of-the-art equipment.
The eye-catching red and black mother-of-pearl front design with oversized chrome logos makes the Layla AION one of the most visually appealing monitor headphones ever.
Silver Plated OFC Litz Wire Cable With 7-Pin Connector
The strongest, lightest, most durable cable ever. The high-purity OFC 4N German-made, military-grade, silver-plated cable with iridium connectors is designed to provide a tight grip on the connection while making it easy to plug and unplug.
The internal O-ring protects the cable and earphones sweat-proof, and the cable is not oxidized.
USA Made Handcrafted Headphones
