Gaming earbuds have long operated on an unspoken assumption: that total audio immersion requires cutting yourself off from the world around you. Sealed tips, passive isolation, the whole sensory cocoon. The ROG Cetra Open Wireless throws that logic out entirely, producing a pair of gaming earbuds that wants you to hear both the firefight and the person calling your name from the other room.
The open-ear design rests outside the ear canal rather than sealing into it, sitting against the outer ear with liquid silicone hooks that wrap around the back. It is the same air conduction approach used in sports earbuds, where hearing your environment is a feature rather than a flaw. The difference here is that ROG has tuned the hardware around gaming, not just fitness, which changes both the driver choice and the connectivity options.

Each earbud is built around a 14.2mm diamond-like carbon-coated diaphragm driver. DLC coatings are favored in higher-end audio hardware because the material’s rigidity resists deformation at high frequencies, resulting in cleaner transient response and lower distortion. Open-ear designs lose low-end naturally from air leakage, so ROG included Phantom Bass, a perceptual processing mode that restores the sense of low-frequency weight without sealing the canal.
The connectivity is where the gaming identity becomes explicit. Bluetooth 6 handles general pairing, but the included USB-C 2.4GHz dongle, running ROG’s SpeedNova technology, delivers latency 6 times lower than Bluetooth mode. That difference is meaningful in competitive play where audio sync affects reaction timing. The dongle also supports one-way passthrough charging, keeping a phone powered while the low-latency connection stays active.
Communication gets its own dedicated hardware: four MEMS microphones arranged for beamforming pickup, with AI noise cancellation suppressing ambient sound in real time. ROG’s testing, conducted by PAL Acoustic Technology, a Microsoft-certified third-party lab, puts the MOS-LQO voice quality score at 4.1, clearing the Microsoft Teams certification threshold of 3.9. For earbuds worn during commutes or at the gym, that score carries practical weight.
Battery life is rated at 16 hours per charge in Bluetooth mode, with the charging case adding 48 hours more, bringing the combined total to 64 hours. A 15-minute charge delivers 3 hours of playback. Physical buttons handle on-device control rather than touch surfaces, which stay reliable in sweaty or wet conditions. EQ profiles, button mappings, and lighting are all adjustable through Gear Link, a browser-based tool that needs no software installation.
The ROG Cetra Open Wireless is priced at $229.99 and available through the ASUS eStore, Amazon, Micro Center, and Newegg. For gaming earbuds that pull off the unusual trick of staying useful to a competitive mobile gamer and to someone who simply cannot afford to be sonically sealed off from their surroundings, it makes a harder argument against itself than the open-ear format usually does.
