Asus presented the ROG Delta II under its ROG gaming brand at Computex 2024. The premium gaming headset follows on visually from its predecessors, the ROG Delta and ROG Delta S, but comes with significantly better sound and new functions. I was able to take a closer look at the device.

Asus ROG Delta II: Design, workmanship, comfort

Medium weight
Fit more for large heads
Strange attachment of the ear pads

If you’ve seen a ROG headset before, you won’t be surprised by the Delta II. The headset comes in black with anthracite-colored connectors. The shells have a typical ROG triangular shape and are not round or oval like most other headsets. The headband is covered with black faux leather, which is relatively discreetly embossed with the “Republic of Gamers” lettering.

Of course, the ROG Delta II has RGB lighting, which is also quite discreet, only the edge of the triangle on the ear cups and the ROG logo on it are illuminated. If you’re looking for Christmas lights for your head, you’ll have to look elsewhere.

The 50 millimeter titanium drivers do a fantastic job with the sound. In fact, it’s as good as a higher-priced gaming headset.

The controls on the headset are nice and clear. On the left-hand side is the wheel for adjusting the volume of the wireless connection, which also serves as a button for muting the microphone. Below there’s a function button for wireless mode and below this is the on/off switch for wireless or 2.4 GHz mode, which you can use to switch the headset on and off when it’s not connected to another device via Bluetooth.

This is followed by a USB-C port, which is only intended for charging and firmware updates, and the slot for the microphone, which is of course detachable. The rest of the controls are located on the right-hand side, where you’ll find a second wheel for the volume control of the Bluetooth connection (but without a button function), the corresponding function button for the Bluetooth connection, and a 3.5 millimeter jack socket for the wired connection.

As soon as you unpack the ROG Delta II, you notice how light it feels in your hands, even though it weighs just 318 grams, which puts it solidly in the midrange category of wireless gaming headsets. The clamping pressure is also pleasant, but without being too loose that the headset would fall off the head.

The fit is unusually large. I’m not blessed with a petite skull and therefore intuitively set the headband size a few steps higher, only to reduce it to a minimum afterwards, completely baffled. The ROG Delta II is definitely not for small heads, maybe just enough for voluminous hairstyles.

The headset is basically made of plastic, although a metal clip is used in the headband. Nevertheless, it feels quite high-quality overall, not cheap. My biggest criticism is the “mechanism” with which the ear pads are attached to the headset. You have to fumble the rubber lip on the cushion into the corresponding gap on the headset. Other manufacturers use magnets or a rotating mechanism for this.

Asus ROG Delta II: Range of functions

2.4 GHz, Bluetooth and jack
Wireless and Bluetooth simultaneously
Lighting synchronized with other ROG hardware

The range of functions leaves little to be desired. The ROG Delta II can connect to your devices in three different ways: latency-free via radio (2.4 GHz, ROG Speednova) thanks to the supplied dongle, via Bluetooth, or via a 3.5 millimeter jack cable. Although the headset has a USB-C port, it cannot be used as a USB device. As mentioned above, the connection is only used for charging and firmware updates.

The special thing about the ROG Delta II is that it can play two audio sources simultaneously. This means you can connect it to your PC or PlayStation for gaming and to your mobile phone at the same time. If someone calls, for example, you can use it to make a phone call without interrupting the game sound.
