Among the many leaders in Spartan history, King Agis II stood out as a ruler of both strategic brilliance and battlefield valor. To honor his legacy, Noble Audio has meticulously tuned the Agis II to reflect his strength, control, and clarity through an elite driver setup:
- 2 Sonion bone conduction drivers
- 1 Sonion BA driver for low frequencies
- 2 Sonion BA drivers for high and ultra-high frequencies
- 2 Knowles BA drivers for the lower mids and mids
- 3 additional balanced armatures for layered depth and detail
This configuration brings out outstanding spatial resolution and a high-definition sound signature, allowing listeners to experience music with stunning realism and emotional impact.

Agis II isn’t just about powerful internals—it’s also a visual tribute to Spartan valor. The faceplate design takes inspiration from the iconic crimson cloaks worn by Spartan warriors and is finished in a bold bronze-gold colorway, symbolizing honor, glory, and leadership. Every detail evokes the spirit of a battle-tested king.

To ensure optimal bone conduction performance and comfort, the Agis II shell has been crafted using Noble Audio’s internal ear impression database. The ergonomic design enhances acoustic sealing, adapts to a wide range of ear shapes, and delivers both excellent isolation and efficient sound transmission. Like the physique of a seasoned warrior, the Agis II’s form is strong, defined, and built for battle.

The Agis II comes equipped with Noble Audio’s upgraded Standard Cable 2023, an 8-core cable comprising 336 strands of single-crystal copper and silver-plated copper conductors. This cable is engineered to elevate vocal clarity, instrument separation, and overall spatial imaging.
To maximize compatibility, the cable includes interchangeable 4.4mm, 3.5mm, and 2.5mm plugs. Internally, the use of Kelvar-reinforced materials ensures outstanding durability without compromising sound quality—making it ready for any sonic battlefield.
