Going all the way back to that first Strix headset, Asus used a unique triangular shape to its earcups and the original ROG Delta had a similar shape and the new Delta II does as well. The new Delta II looks very similar to the original Delta designs, but you can see big changes with the earcup mounting having just one side attached whereas the old design had arms on both the front and back. The earcups have a similar shape but have changed and the headband design is new as well. The Delta II is black with a few of the touches like the arms being a dark grey. This design has full-sized earcups designed to go around your ears and they advertise it as a lightweight wireless headset sitting at 318 grams but it does weigh more than the older Delta S Wireless which was 310 grams. They are lighter than something like the Astro A50 X Wireless or the Logitech G pro X 2 Lightspeed which was 345 grams. Corsair’s HS80 Max Wireless is 352 grams and Razer’s Kraken V4 is 350 grams so Asus is coming in significantly lower than the competition there. Frankly, I’m just happy to see that weight is finally being focused on at all because it plays a big role in how comfortable a headset is in extended use.
So both sides of the Delta II have things going on. Often with wireless headsets or headsets in general you will see all of the functions packed into one side. The left earcup is the main side though. That side has the plug for the detachable microphone which has a standard 3.5 mm plug but a unique shape around it to lock the microphone in place. It is tight, but if you wanted you could plug in a different microphone like a lapel microphone if you wanted but I don’t know if it would work. That side then has the charging port which is a USB Type-C plug. This is great news if you already have USB Type-C charging at your desk, which a lot of people do for other devices including their phones. Then there is an on and off switch but this is specifically for turning on 2.4 Ghz mode using their dongle, powering on Bluetooth mode is on the other side and is a little confusing. Next to that is a single button, this is what they call the function button. One press is play or pause, two presses goes to the next song, and three presses will go to the previous song. Then you can press and hold for 5 seconds to turn the RGB lighting on or off and hold for 15 seconds to factory reset the Delta II’s settings. They really pack a lot into one button. Next to that is a volume wheel, again just for the 2.4 Ghz audio, you can also press down here and mute or unmute your microphone. On the right-hand side, you have a second audio volume wheel, this is for controlling your Bluetooth volume but it doesn’t have the microphone mute function like the other volume wheel. Below it is another function button that has the same play/pause, next, and previous functions. Holding it for three seconds turns Bluetooth mode on or off and if you are receiving a call pressing once will answer or end the call and two presses will reject the call which seems risky to me lol. The reason for the confusing double set of controls is because the ROG Delta II can connect to both audio sources at the same time. In fact, you can also plug in using the 3.5 mm wired plug which they include to help with console compatibility as well.
The earcup shape of the Delta II is more defined from the side profile but this is also where some of the visual changes from the past Delta’s can be seen. The biggest change is in the mounting arm that comes down from the headband and holds each earcup. In the past, these would split and hold the earcup from the front and back but that has changed to a thicker aluminum mount with just the one arm going to the back for a cleaner look. That arm can pivot side to side and allows the earcup to tilt up and down as well to get the best possible fit for all head shapes. In typical ROG fashion, the Delta II does have RGB lighting with a full ring around the earcup as well as the ROG logo on the side. Asus went with 50mm titanium-plated diaphragm drivers. They have a frequency response range of 20Hz - 20KHz and the headphones have an impedance of 32 ohm. On the inside the padding has that same unique shape with the stock padding having a leather-like finish and the second swappable pads having a softer fabric finish depending on what your preference is. The leather-like finish will seal out more background noise but will be hotter whereas the fabric will breathe a little but let in background noise. Inside over the drivers they have the ROG logo again as well.
The thick aluminum mounts on each earcup lead up into the headband and can be adjusted in and out to fit a range of head sizes. The outside of the headband up on top has that leather-like finish with the full ROG branding embossed into it. Then on the underside, there is padding but that starts just past the silver straps you see. Anything below that has fabric over it but no padding. The top has thick padding however and that’s the only place the headset should be touching your head, beyond the earcups.
The front edge of the left earcup has the boom microphone and this is removable. It comes detached and plugs in with a standard 3.5mm jack and has a specific shape inset on the headset to lock the microphone in place. It has a rubber covering on the flexible boom and at the end a thick foam pop filter that goes over the microphone. The pickup pattern for the capsule is unidirectional so it will be focused at your mouth to help cut down background noise. It has a frequency response of 100Hz - 10KHz and a sensitivity of -40 dB.
