ROG Cetra Open Wireless Review: Gaming Earbuds Without the Seal

Introduction

The ROG Cetra Open Wireless represents a significant departure from traditional gaming audio. Rather than sealing sound into the ear canal, these open-back true wireless earbuds deliver gaming performance without the isolation or heat buildup of conventional designs. For players who spend extended sessions at their desk or want flexibility across gaming and outdoor use, this approach addresses a real comfort gap.

The earbuds combine Bluetooth 6.0 with a 2.4GHz USB-C dongle for low-latency gaming, RGB lighting for aesthetic customization, and a detachable reflective neckband that transforms them into a neck-worn option. This is the first open-back gaming true wireless on the market, making it a notable entry point for a category that has remained largely unexplored.

Design and Build Quality

The charging case follows ROG’s signature aesthetic: a flat, elongated black matte design with faux-leather texture embossing that provides grip without slipping. The interior maintains the brand’s diagonal stripe motif, and the 2.4GHz dongle sits neatly inside, eliminating the need for a separate pouch.

The earbuds themselves weigh just 11 grams each and use a skin-friendly silicone ear-hook design. The outer surface combines mirrored and matte finishes, with the distinctive ROG eye logo rendered in mirrored material that supports Aura RGB lighting. Physical buttons replace touch controls, reducing accidental activation and fingerprint smudging on the logo area.

The included detachable reflective neckband is a practical addition that allows the earbuds to function as a neck-worn option for outdoor activities. This dual-mode capability means the same earbuds can serve both stationary gaming sessions and active use without requiring a separate product.

Connectivity and Versatility

The 2.4GHz dongle uses an extended design that accommodates thick phone cases without obstruction. It supports USB-C pass-through charging, allowing simultaneous gaming and battery replenishment. The dongle works across PC, Mac, PlayStation, Switch, and mobile platforms.

The earbuds support dual-mode connectivity: 2.4GHz dongle plus Bluetooth, or dual Bluetooth connections. The 2.4GHz mode includes SpeedNova low-latency technology, which allows simultaneous game audio and voice chat without compressing game sound to mono as standard Bluetooth does. This separation is particularly valuable for competitive play where both audio channels carry critical information.

Battery life reaches 16 to 40 hours depending on RGB and feature usage. The earbuds carry IPX5 water resistance, while the case is IPX2 rated. The dongle itself lacks water protection, a practical trade-off for its extended design.

Sound Quality and Gaming Performance

The acoustic design uses a 14.2mm DLC diamond-like carbon driver tuned to a modified Harman curve. By default, the earbuds enable a “phantom bass” feature that reinforces low-frequency punch and body, compensating for the open-back design’s inherent bass rolloff. Disabling this mode reveals a leaner, more neutral low-end closer to the diffuse-field Harman target.

Midrange presence is slightly elevated, giving both male and female vocals noticeable thickness. This tuning choice supports in-game voice clarity, helping players hear teammate callouts and enemy audio cues. The open-back design delivers a wide soundstage with good left-right separation, allowing directional awareness of footsteps and environmental sounds. The midrange has been enhanced to preserve footstep detail without making metallic sounds like knife strikes harsh or fatiguing. Phantom bass doesn’t mask footstep information, maintaining the audio hierarchy needed for competitive play.

Immersion Mode and Additional Features

An “Immersion Mode” function acts as a conservative active noise cancellation system, targeting low-frequency room noise such as PC fan hum and ambient hum. This helps compensate for the open-back design’s lack of passive isolation. The effect is subtle and focuses primarily on low frequencies, with minimal ear pressure sensation.

The Gear Link web interface and companion app allow full RGB customization and access to additional sound modes. A “Clear Audio” mode enhances high-frequency detail for music listening. The dual-ear, four-microphone array supports AI-driven call noise reduction for voice communication. Virtual surround sound is available through the web interface extension, useful for media consumption but typically disabled during competitive gaming.

Conclusion

The ROG Cetra Open Wireless fills a genuine niche: gaming audio for players who reject the isolation and heat of sealed earbuds but want low-latency performance and competitive features. The open-back design, dual connectivity, detachable neckband, and cross-platform support make it a versatile choice for gamers who also value outdoor flexibility. The build quality and attention to detail reflect ROG’s experience in peripheral design, and the feature set is comprehensive without requiring excessive software installation.
