In today’s ASUS ROG Cetra II Core review, we’ll check out ASUS’ latest in-ear gaming headset under their ROG line.

Hands-on with the ASUS ROG Cetra II Core

We also tested the product for our ASUS ROG Cetra II Core review to know how well it performs. During our tests, we used the headphones while playing several games and connected it to different platforms. Aside from games, we also checked its audio quality for music.

In terms of gaming, we were quite surprised that these in-ear headphones delivered impressive performance. For FPS games, we could hear the enemy’s footsteps clearly without having to crank up the volume to max. As for the bass, it was also extremely powerful and we loved this a lot. 

When it came to mobile games, these in-ear headphones delivered excellent audio as well. While playing single-player titles such as Genshin Impact, the Cetra II Core delivered clear and clean audio output. There were tons of bass and power which made the gameplay more exciting and immersive. 

Another element we loved about the pair is that they weren’t difficult to drive. We found that setting the volume at 50% was enough for our needs. 

Its staging wasn’t as wide compared to those full-sized headphones. Despite that, the product still gave us a huge advantage in FPS titles compared to using a smartphone’s speakers.

When we paired the in-ear headphones with a couple of smartphones, the sound output was quite neutral. When we tried it with iPhones and other Androids, we needed to adjust the equaliser and lower the bass levels. We did this to prevent it from getting too warm and close to the highs and mids. 

Overall, its audio quality was excellent, though on some devices, we had to make a couple of adjustments first. 

For this ASUS ROG Cetra II Core review, we also listened to different music like Pop, R&B, EDM, etc. It sounded great, but if you’re someone who prioritises vocals, it might sound less dominant with the Cetra II Core.

For potential sound leakage and passive noise isolation, the in-ear headphones worked just like how they should. We were entirely isolated from our surroundings and everyone around us couldn’t hear what we were listening to.
