By ditching the usual boom mic and RGB lighting, the Asus ROG Delta S Wireless gaming headphones are unlikely to attract any unwanted attention on your daily commute. They are also very comfortable, and can wirelessly connect to your PC, console, or even Android smartphone via a small USB-C dongle that can be stowed in the right earcup.

With its lack of LEDs and a clean black-and-white aesthetics, the Delta S Wireless looks very different from most Asus ROG headsets. In fact, these headphones remind me of the Asus Strix Go 2.4, but with some tweaks. Notably, the Delta S Wireless has concealed beamforming mics instead of a boom mic. I also like how you can keep its USB-C dongle in a slot in the right earcup, which means you're less likely to lose it. This USB-C dongle uses the 2.4GHz wireless frequency to connect the headphones to your device. It's very convenient as unlike Bluetooth, you don't have to pair it — it's really plug and play. Both the 2.4GHz and Bluetooth connections appear to have a similar effective range. They both cut off at the same spot in my home, with a couple of walls in between the headset and my phone.

The D-shape ear cups are large and comfy, especially the default protein leather version. Like the Asus ROG Fusion II 500, the Delta S Wireless comes with a spare set of ear cups made from breathable fabric mesh more suited for our humid climes. The padded headband feels soft, while the headphones do not clamp tightly on my ears. You can rotate the earcups to lie flat, but you cannot fold them into a more compact form. Overall, these headphones are very comfortable. All the controls, like the volume rocker and input switch are on the left ear cup. The Bluetooth pairing button also controls the media playback. For example, you can press it twice to skip forward, and thrice to skip back.

While the Delta S Wireless works out of the box, you'll get the best experience by installing the Asus Armoury Crate app on your PC. This app lets you tweak the sound, as well as enable effects like virtual surround sound, and update the firmware. By default, the headphones sound pretty flat and neutral, so they benefit from some adjustments using the equaliser. The bass, for one, could do with some boosting. Footsteps and gunfire all come across well in games in terms of direction, but I found it difficult to gauge the distance of the sound effects. Asus should also streamline the app's audio options, which can be overwhelming. The mic is passable in terms of clarity, but the noise cancellation seems undercooked.

Asus says the battery life of the ROG Delta S Wireless is around 25 hours, while a 15-min charge can provide around 3 hours of uptime. In my testing at 50% volume, the battery depleted by 5% after an hour of use. At S$299, the Asus ROG Delta S is much cheaper than the Sony Inzone H9 (S$499). But there are also more affordable wireless gaming headsets from the likes of Kingston HyperX and SteelSeries. What makes this Asus worth considering is its comfort, and relatively lightweight yet solid build. And it works with practically any device with a USB-C port. Get it now at Shopee, Lazada or Amazon US.
