ASUS is adding another audio product to its Republic of Gamers lineup, but this one takes a different route than the usual closed-back gaming headset. The new ROG Cetra Open Wireless is a pair of open-ear wireless earbuds built for people who want game audio, voice chat, and music without fully shutting out the world around them.

That open design is really the whole point here. Instead of sealing off your ears like traditional earbuds, the Cetra Open Wireless sits in a way that lets outside sound still come through. For some people, that will be the main appeal. You can hear your game, your call, or your playlist, but still stay aware of traffic, coworkers, family members, or whatever else is happening around you.

ASUS is clearly aiming at a specific kind of user with these earbuds. This is not just a product for someone sitting at a desk with a gaming PC all day. The Cetra Open Wireless is also being positioned for mobile play, handheld gaming, casual listening, and workouts. In other words, ASUS is trying to make one set of earbuds cover a lot of ground.

Open-ear earbuds have been gaining traction lately, especially among people who use them while walking, running, or working out. What makes the ROG Cetra Open Wireless stand out is that ASUS is blending that style with features that are usually associated with gaming gear.

The earbuds support dual wireless modes. You can connect over standard Bluetooth for everyday use with phones, tablets, and laptops, or switch to 2.4GHz wireless using ASUS’s ROG SpeedNova technology. That second option is the more gaming-focused one, since it is meant to reduce latency and keep audio better synced with what’s happening on screen.

ASUS says the earbuds are compatible across a wide mix of platforms, including PC, Mac, PlayStation, Nintendo Switch, iOS, and Android. That broad support matters because cross-platform play is now normal for a lot of people. Many users bounce between console, handheld, phone, and laptop depending on where they are, and ASUS seems to be building around that reality.

There is also a USB-C wireless dongle in the box, and it includes passthrough charging. That means you can keep charging a connected device while still using the dongle. It is a practical feature, especially for handheld gaming or longer sessions on devices with limited ports.

Inside the earbuds are 14.2mm drivers with a diamond-like carbon coating. That coating is meant to help reduce distortion and keep the sound cleaner, especially through the highs and mids, while still preserving bass presence.

That last part matters because open-ear designs usually have a harder time delivering the kind of low-end impact people expect from sealed earbuds. ASUS is trying to work around that with software as well as hardware.

The Cetra Open Wireless includes built-in sound modes such as Phantom Bass and Immersion Mode. Phantom Bass is designed to restore some of the low-end perception that open earbuds can lose because of their non-sealing design. Immersion Mode, meanwhile, is meant to reduce certain low-frequency background sounds like traffic, fans, or general rumble so you can focus more on what you are listening to.

That does not turn these into noise-isolating earbuds, and ASUS is not really pretending otherwise. The idea seems to be more about balancing awareness and focus rather than choosing one or the other completely.

One small but notable choice here is that ASUS uses physical buttons instead of touch controls. That may not sound exciting, but it could be a smart move. Touch controls can be annoying when you are adjusting an earbud during a workout or dealing with sweat or light rain. Physical buttons are usually easier to trust because you know when you have actually pressed something.

The earbuds also use liquid silicone ear hooks for a more secure fit, and ASUS includes a detachable reflective neck strap for added stability during exercise or outdoor use. There is also an IPX5 splash-resistance rating, which should make them better suited for sweat and light rain than a standard pair of everyday earbuds.

For voice pickup, ASUS includes four microphones with AI noise cancellation to help make calls, chat, and streaming communication clearer.

Battery life is one area where the Cetra Open Wireless could get attention. ASUS rates the earbuds for up to 16 hours on a full charge in Bluetooth mode, assuming RGB lighting and sound modes are turned off and the microphone is muted. A 15-minute quick charge is said to provide up to 3 hours of listening time.

The charging case adds 48 more hours, bringing total battery life to 64 hours. If that number holds up in real-world use, it would put these in a very strong position for people who do not want to recharge constantly.

At $229.99, the ASUS ROG Cetra Open Wireless is not trying to compete as a budget earbud. Instead, it is aiming for a niche that is getting more interesting: people who want a lightweight, portable alternative to a gaming headset without giving up features like low-latency wireless, platform flexibility, and clear voice support.

The bigger question is whether enough gamers actually want an open-ear setup in the first place. For some, the ability to stay aware of their surroundings will be a major advantage. For others, the lack of a sealed, isolated fit may still make traditional gaming earbuds or headsets the better choice.

Either way, ASUS is betting that gaming audio does not always have to mean blocking everything else out. The ROG Cetra Open Wireless is available now in black for $229.99 at Amazon.
