What They Are

The ASUS ROG CETRA II CORE in-ear headphones use 9.4 mm liquid silicone rubber drivers and a 3.5 mm connector to deliver strong bass and clear audio across PC, PlayStation 5, Xbox Series X/S and Nintendo Switch. A 90° cable connector and lightweight metal housing keep the fit comfortable during long handheld or desktop sessions.

Capacity and Headroom

Frequency response reaches 20 Hz – 40 kHz with 32 ohm impedance, so music and game soundtracks reproduce deep lows and extended highs without an external amplifier. The inline microphone captures voice at 50 Hz – 10 kHz with -40 dB sensitivity, handling in-game chat and calls cleanly until ambient noise overwhelms the pickup.

Build Integration

The 1.25 m cable plugs directly into any 3.5 mm jack, removing the need for adapters, dongles or batteries. Ultrasoft LSR ear fins and tips create a secure seal that isolates sound passively, freeing the user from active-noise-cancellation hardware while keeping the package light and pocketable.

Questions about this item

Will the 3.5mm connector work with my older laptop that only has a single combo audio jack?

Yes, the 3.5mm plug uses the standard CTIA pinout, so it functions correctly with any laptop or desktop that provides a combined headphone and microphone jack.

How can I confirm the 9.4mm liquid silicone rubber drivers are performing as intended?

Play a track with deep low-end content; the drivers should reproduce frequencies down to 20Hz without distortion, and the 32ohm impedance ensures adequate volume from standard device outputs.

Does the package include replacement ear tips or do I need to purchase them separately?

The box contains the in-ear headphones with pre-installed LSR ear fins and tips plus additional sizes in the bundle, so no separate purchase is required for a secure fit.
