ASUS ROG Cetra II Core Review - Bass Heads, Rejoice!

The Package »



The ASUS ROG Cetra II Core is a successor to an in-ear gaming headset I'm completely unfamiliar with, so in this review, I'll examine it as a standalone product rather than compare it to the original ROG Cetra. What's the point of a wired in-ear headset in 2021, you might ask, especially as most users seem to lean towards TWS headphones? There's a good reason why wired in-ears still have an audience: latency. While Bluetooth headphones are perfectly fine for music, YouTube, Netflix, and casual mobile gaming, many of them don't support or have poorly implemented low latency Bluetooth codecs, such as Qualcomm's aptX Adaptive, which makes them downright unusable for multiplayer shooters, rhythm titles, instrument apps, and anything else exceptionally latency-dependent. There's also the issue of having to worry about battery life; some users find this unacceptable and choose to embrace the slight inconvenience of using a headset with a wire.

The ASUS ROG Cetra II Core is actually a stripped-down edition of the ROG Cetra II, in the sense that it utilizes basic 3.5-mm connectivity and thankfully offers no RGB effects, while the "regular" ROG Cetra II earpieces will light up in the color of your choice and connect to your device via USB-C. In a way, that makes the less expensive ROG Cetra II Core more versatile, as you'll be able to connect it to just about any device you might own: desktop PCs, laptops, PlayStation 5, Xbox Series X, Nintendo Switch, as well as smartphones. In case your phone isn't equipped with a 3.5-mm port, a simple USB-C audio adapter, such as the affordable Sharkoon Mobile DAC, will solve that problem. The "regular" ROG Cetra II also offers the Active Noise Cancellation technology, which isn't supported by the ROG Cetra II Core, although I don't see this as a massive issue since in-ear headphones usually inherently offer an excellent level of passive noise isolation. Without further ado, let's examine the ASUS ROG Cetra II Core to find out if this $90 in-ear gaming headset is worth your attention.
