ULTRA-SYNCED, ULTRA-IMMERSED

The ROG Cetra True Wireless SpeedNova gaming headphones offer unmatched versatility with Bluetooth and ROG SpeedNova 2.4 GHz wireless technology, providing ultra-low latency gaming audio. 24-bit 96 kHz audio, Dirac Opteo, and Adaptive ANC with Auto mode combine to immerse you in high-resolution audio, while Bone-Conduction AI Microphones ensure superior call quality. And with up to 46 hours** of battery life, ROG Cetra True Wireless SpeedNova keeps the audio going all day long.

Dual-mode Wireless Connections

You can enjoy unrivaled flexibility with Bluetooth and ultra-low latency 2.4 GHz connections.

ROG SpeedNova Wireless Technology

Together with the USB-C dongle, ROG SpeedNova wireless technology optimizes the 2.4 GHz band to deliver ultra-low latency audio performance and a robust connection. It's also more energy efficient, providing up to 36 hours of battery life* for marathon gaming.

Realistic Audio

ROG Cetra True Wireless SpeedNova takes advantage of the LC3+ codec to deliver high-resolution 24-bit 96 kHz audio*. Additionally, Dirac Opteo offers rich details and accurate sound staging for true-to-life listening experiences.

Bone-conduction AI Microphones

The absence of a boom mic makes clean and clear voice pickup a challenge for earbuds.

The bone-conduction sensors of ROG Cetra True Wireless SpeedNova capture voice from vibrations of the bones in the wearer's skull.

Together with the AI Noise-Canceling beamforming microphones, they effectively reduce background noise while maintaining natural sound to ensure crystal-clear calls.

ADAPTIVE ANC

Adaptive ANC delivers major enhancements in noise cancelation as it makes real-time adjustments by constantly detecting how the earbuds are worn and how sound is reflected within the ear canal for perfect listening experiences. Plus, integrated wind noise reduction optimizes the ANC effect for fully immersive audio.

AUTO MODE

Whether on a noisy street or a quiet café, a smart Auto mode identifies ambient noise and automatically adapts to surroundings, dynamically adjusting noise cancelation levels for improved comfort in quiet environments.

Ready for Play,All Day

The charging case works wirelessly or via a USB-C®connection. Fast in-case
