Overview
Open-ear wireless earbuds from the ROG line, built with dual Bluetooth and 2.4GHz connectivity and 14.2mm drivers for gaming, workouts and daily use where staying aware of surroundings matters.
Open-ear here means the earbuds sit outside the ear canal so ambient sound still comes through, which is a different feature from noise cancellation and worth not confusing: the quad mic array is for canceling background noise on calls, not for blocking outside sound while listening. USB-C passthrough charging is one-way only, letting the earbuds draw phone power without the earbuds charging back.
- Dual-mode Bluetooth and 2.4GHz connectivity
- 14.2mm DLC-coated drivers
- IPX5 water resistance
- 16 hour battery with fast-charge top-up
Who it's for
Fits gamers and active users who want to hear their surroundings while gaming, working out or commuting, and who value all-day comfort over sealed-in bass. Not the pick for anyone wanting isolation from outside noise.
Pros and cons
- Low-latency 2.4GHz mode for gaming
- Open-ear design keeps ambient awareness during use
- IPX5 water resistance for workouts
- Detachable, reflective neck strap guards against drops
- Open-ear design does not isolate or cancel outside noise for listening
- USB-C passthrough charging is one-way only
Performance notes
The ROG SpeedNova 2.4GHz mode is built for low input lag versus standard Bluetooth, which matters for gaming timing, while Bluetooth mode covers everyday phone use. IPX5 protection covers sweat and rain exposure during workouts, and the ear hooks with a detachable neck strap are meant to keep the buds secured and visible rather than dropped.

Frequently asked questions
Do the ASUS ROG Cetra Open Wireless earbuds cancel outside noise?
No. The open-ear design intentionally lets ambient sound through; the quad AI noise-canceling mic is for reducing background noise heard by others on calls, not for blocking sound for the wearer.
How long does the battery last?
Up to 16 hours per charge, with a 15-minute fast charge adding about 3 hours of use.
Can the USB-C port charge my phone from the earbuds?
The passthrough charging is one-way only, meaning it can power your phone but the earbuds themselves are not charged through that connection.
