Open-ear earbuds have been having a serious moment. Brands like Shokz and Samsung have leaned hard into the "hear your surroundings" pitch, winning over commuters, runners, and anyone who's been startled one too many times by an approaching cyclist. Now, Asus is taking that same concept and pointing it squarely at mobile gamers with the ROG Cetra Open Wireless Earbuds.
A gaming bud that breaks the mold
The idea is a bit counterintuitive at first. Gaming audio has long been about immersion - deep bass, precise directional sound, and blocking out the outside world so you can focus. Open-ear designs do the opposite, keeping you connected to your environment rather than sealing you inside it. So who exactly is this for?
Asus seems to be betting on a specific kind of gamer: one who plays on their phone, maybe on a commute or in a shared space, and needs to stay aware of what's happening around them. Think someone grinding through a mobile RPG on the subway, or a casual player who still wants to have a conversation mid-session without yanking out their earbuds.
ROG branding meets open-ear design
The Cetra Open carries all the visual DNA you'd expect from the Republic of Gamers line - angular design, a look that signals "I am definitely a tech person." The wireless functionality removes the tangle of cables that typically comes with budget gaming audio, which is a welcome step forward for on-the-go use.
According to a review from Wired, these earbuds are designed with mobile gamers specifically in mind, positioning them in a niche that sits somewhere between dedicated gaming headsets and everyday lifestyle earbuds. That middle-ground positioning is interesting, because it means they're not really competing with a traditional ANC-focused bud or a full over-ear gaming headset.
The real question: does open audio work for gaming?
Here's where it gets genuinely interesting. Open-ear audio has real trade-offs. You get ambient awareness, but you sacrifice bass depth and audio isolation - two things that tend to matter quite a bit when you're trying to catch footsteps in a shooter or get lost in an immersive RPG soundtrack.
For casual mobile gaming, those trade-offs might be completely acceptable. Not every gaming session is a ranked competitive match that demands laser focus. Sometimes you just want decent audio while you play something low-stakes, without feeling cut off from the room.
The Asus ROG Cetra Open is a niche product, but it's an honest one - designed for a real use case rather than manufactured to tick spec-sheet boxes. Whether that use case matches your own gaming habits is the only question that really matters before considering a pair.
