Open-Ear Gaming Earbuds

The ASUS ROG Cetra Open Wireless earbuds weigh 11.4 grams each and use 14.2 mm DLC-coated drivers with a 20 Hz to 20 kHz response. They connect through Bluetooth or low-latency 2.4 GHz wireless via a USB-C dongle. An IPX5 rating protects against sweat and rain. The charging case weighs 110 grams and holds enough power for 64 hours of total playback. A 15-minute charge adds three hours of use.

Who These Suit

Gamers who need situational awareness will like the open-ear design that lets ambient sound in. The AI noise-cancelling microphone filters background noise for clear chat. RGB lighting on the earbuds syncs with Aura RGB software. The package includes a reflective neck strap, USB-C to USB-A cable and quick-start guide. Buyers who want active noise cancellation for the ears themselves should look elsewhere.

Battery and Capacity

The earbuds deliver up to 16 hours of continuous play on a single charge. The case extends total listening time to 64 hours. Fast charging restores three hours of runtime in 15 minutes. The USB-C port on the case supports passthrough charging for a phone while the earbuds are in use. The 16 ohm impedance and 100 Hz to 8 kHz microphone response handle voice communication and music playback without extra equipment.

Questions about this item

What type of USB port does my device need for the included 2.4 GHz dongle?

The wireless dongle uses a USB-C connector, and a USB-C to USB-A cable is supplied for charging or for devices with only Type-A ports.

Will the open-ear design still let me hear game audio clearly while I keep my existing wired headset on my desk?

Yes, the 14.2 mm DLC-coated drivers deliver 20 Hz–20 kHz frequency response and Phantom Bass enhancement without blocking your ears, so you can switch between them instantly.

How can I confirm the AI noise-cancelling microphone is active after pairing?

The microphone operates at 100 Hz–8 kHz with –38 ± 3 dB sensitivity; when the quad-mic array engages, background noise drops noticeably during voice chat or calls.
