Asus has launched the Cetra Open Wireless earbuds, a specialized audio solution designed primarily for handheld gaming devices. The new peripheral specifically targets users of platforms like the Steam Deck and Nintendo Switch 2 who prioritize environmental awareness. According to The Verge, the device distinguishes itself through a unique USB-C transmitter that supports powerful passthrough charging capabilities. This announcement marks a significant step in peripheral innovation for portable gaming enthusiasts seeking convenience.
Unlike traditional gaming earbuds that seal the ear canal, the Cetra Open utilize an open-style design that rests securely outside the ear structure. This specific configuration allows game audio to mix naturally with ambient sounds, providing a sense of immersion without complete isolation. While this design choice inherently limits bass response compared to sealed alternatives, the overall fit remains comfortable for extended gaming sessions. Users can maintain situational awareness without removing the device to hear conversations nearby.
Audio performance relies heavily on Asus Phantom Bass technology, which activates by default to enhance low-frequency output without distorting the signal. Reviewers noted full-bodied sound with solid mids, though the lack of a tight seal prevents deep sub-bass frequencies found in closed-back models. The earbuds function effectively for music consumption during work hours and gaming at night near others without disturbing household members. Listening to game audio at reasonable volumes remains possible even in shared living spaces.
A significant technical differentiator is the included 2.4GHz USB-C audio transmitter featuring robust power passthrough capabilities for connected peripherals. Asus spokesperson Katie Grayum told The Verge the transmitter supports up to 60W one-way charging for connected devices during active use. This feature allows gamers to charge their handheld console while playing, effectively eliminating battery anxiety during long, uninterrupted sessions. The power delivery ensures the device remains operational even during intensive gameplay sessions.
The transmitter does not support video or data passthrough, restricting its utility strictly to power delivery during audio transmission from the console. Battery life reaches up to 16 hours in Bluetooth mode with lights and microphones disabled, though 2.4GHz usage drops this to approximately 10 hours. The charging case itself lacks wireless charging support but replenishes the earbuds quickly in under 20 minutes. Users only need to charge the case twice during the entire testing period to maintain usability.
Connectivity options include multipoint Bluetooth support, enabling connections to two devices simultaneously or one device alongside the 2.4GHz transmitter. Users can switch sources seamlessly without manual button presses, though simultaneous audio playback from both sources is not supported in this specific iteration. Configuration changes require the Armoury Crate app on mobile or the Gear Link website for desktop users to access full customization features. Switching between sources remains mostly seamless despite the hardware limitations mentioned previously.
Customization tools allow users to adjust audio settings, microphone behavior, and RGB lighting effects through the provided software ecosystem. Button presses on the earbuds accept custom commands for single, double, triple, and quadruple taps to control various functions within the game. Audio prompts can be toggled between English and Chinese or replaced with sound effects for a quiet environment. The interface supports granular control over the auditory experience for individual preferences.
Existing competitors like the SteelSeries Arctis Buds and Sony InZone Buds offer active noise cancellation and tighter seals for different use cases. However, Asus positions the Cetra Open as a specific tool for handheld gamers who need situational awareness and charging flexibility. The product fills a niche where comfort and power management outweigh noise isolation requirements for this specific segment. This strategy differentiates the product in a crowded wireless audio market significantly.
The broader market for open-ear audio continues to evolve as manufacturers seek alternatives to traditional in-ear dominance in portable spaces. This release signals a shift toward accessories that accommodate the specific power and connectivity needs of portable gaming hardware. Future iterations may expand passthrough capabilities beyond simple charging if demand persists among the enthusiast community. The industry is moving toward more integrated hardware solutions for the modern consumer.
Gaming peripheral companies are increasingly tailoring hardware to the unique constraints of handheld consoles and hybrid systems. The Cetra Open demonstrates that specialized audio solutions can coexist with general-purpose wireless earbuds in the same ecosystem. Industry observers will watch whether this form factor gains traction beyond the dedicated handheld gaming segment. Continued investment in this niche could redefine portable audio standards for years.
