ASUS's ROG brand is well-known in the PC gaming community, serving as the label for the company's premium gear, which includes GPUs, motherboards, keyboards, mice, and headsets. The ASUS ROG Delta II Tri-Mode Wireless Gaming Headset is a sequel to the company's original Delta headset. We got our first look at it last year at Computex 2024, where we were impressed by its specs and overall features. The versatility here is right up there, with the Tri-Mode of the name referring to the low-latency wireless, Bluetooth, and wired connectivity support of the headset with the ability to connect to two devices - in that you can game and jump on a mobile call at the same time.
A quick look at the ASUS ROG Delta II Tri-Mode Wireless Gaming Headset
The build quality and design make it feel like a premium product worthy of the ROG branding, from the 50mm titanium-plated diaphragm drivers that can handle high-resolution 24-bit 96 kHz audio to the wide-band microphone, designed to carry your voice clearly with depth and detail. The Tri in the naming also refers to the somewhat unique rounded but triangular D-shaped cups. The default out-of-the-box sound might be a little too flat or balanced for most people, but with some quick tinkering, you're looking at exceptional frequency response for gaming, watching media, or listening to music. The tuning here is surprisingly more audiophile-oriented than gaming.
There are also several great little touches, including fabric cushions and a separate volume dial for Bluetooth connections. There's even a standard wired 3.5mm connection option, which is not something you typically see on most modern wireless gaming headsets - adding to the versatility while providing another option if the battery runs out. On the battery front, you're looking at a respectable 110 hours of use over low-latency wireless. However, this is with the vibrant RGB lighting turned off. Yes, the ROG Delta II Tri-Mode Wireless Gaming Headset includes some cool cyberpunk-inspired lighting that also helps it stand out.

Design & Software Support
Design
The ROG Delta II Tri-Mode Wireless Gaming Headset is a premium product and one that sees ASUS actively looking to cover all bases when it comes to the sort of things gamers want. When it comes to the first thing most people notice when putting on a headset, comfort is a key factor; ASUS has created something special here. Alongside sound quality, comfort is arguably one of the most essential features of a gaming headset as you're looking at something that will sit on your head for hours at a time, several times a week. Weighing in at a lightweight 318 grams, weight distribution is even, and ear pressure is nominal with minimal noise bleed.

The ROG Delta II's design is all about going above and beyond, so in addition to the PU leather ear cushions, you've got the option to swap these out with fabric cushions that offer more breathability. As a design decision, the d-shaped ear cups take a minute to get used to. However, there's no added benefit or detriment to going for a slightly difference shape than the more traditional oval that we've all become accustomed to. In addition to Aura Sync-compatible RGB lighting on each cup, you've also got an extensive and intuitive set of physical controls.
In a very cool move, ASUS includes separate controls for 2.4 GHz and Bluetooth on the left and proper ear cups, respectively - which is super handy when in dual audio mode. In addition to a sturdy volume dial, there is also a 'Function' button that provides quick access to media controls, including play/pause, skip forward, and a shortcut to turn off the headset's lighting. The latter is something you might want to consider, as the battery life increases from 24 hours to 110 hours with the lighting turned off.

The ROG Delta II Tri-Mode Wireless Gaming Headset supports ASUS's SpeedNova technology, a low-latency esports wireless solution that ensures there are no issues or delays when it comes to delivering immersive audio. Hardware-wise, the large 50mm Titanium-plater drivers offer high-resolution audiophile capabilities for audio with crisp and detailed sound, while the detachable 10mm wideband microphone (with pop filter) is all about clear and detailed voice chat.
Software Support
As with all ASUS hardware, customization is handled via the company's full-sized Armoury Crate app or the gear and peripheral-centric Armoury Crate Gear. If it's been a minute since you've used the full Armoury Crate app, the good news is that a recent overhaul has made it more modular and something that only installs the components you need or want to use. In addition to an eight-band equalizer for fine-tuning the frequency balance, there are general presets to choose from, covering Communication, Music, Movies, and various gaming genres. These presets also factor in Virtual Surround and post-processing effects, such as Reverb, Bass Boost, Voice Clarity, and a Compressor.

At first glance, the eight-band equalizer appears to be a step back compared to other apps seen in competing headsets, but separating the frequency adjustment from post-processing features like Bass Boost and other elements is a clever approach for the ROG Delta II's high-quality 50mm drivers. The quality of the Reverb is surprisingly decent, rivaling the reverb tools found in expensive music creation and audio editing software. All of the post-processing sounds natural and distortion-free, including the virtual surround, which is fantastic. The microphone also features a range of enhancements, including echo and noise cancellation, as well as a Perfect Voice slider that enhances your voice to make it sound richer and fuller.

Armoury Crate is also where you can adjust the audio bit-rate or quality, from 16-bitg 48 kHz right up to high-resolution 24-bit 96 KHz. The latter is only really noticeable with actual 24-bit audio, namely a high-quality media file or a lossless audio recording. Weirdly the microphone Sidetone settings, which is only available during phone calls, is found under the general settings tab and not the Microphone one. Throw in lighting customization and the option to adjust power saving features and notifications and the ROG Delta II Tri-Mode Wireless Gaming Headset's customization options are impressive.
Performance & Microphone Quality
Performance
The default out-of-the-box sound of the ROG Delta II Tri-Mode Wireless Gaming Headset can be a little disconcerting if you're not used to hearing a balanced pair of headphones designed primarily for listening to music - which is the domain of most audiophile-related gear. What this means is that without tuning or selecting a preset you're left with a flat sound that lacks punch or the usual wow-factor bass response that most gaming headsets deliver. However, when that initial flat sound is born from excellent drivers and codecs, tuning or adjusting can deliver stunning results - which is definitely the case here. Switch over to the 'Gaming' present and playing Diablo 4 and Assassin's Creed Shadows becomes truly immersive with all of the nuance and detail in each game's sound design and soundtrack brought to life.

As always the FPS option is the exception as that preset is all about making footsteps and other subtle sounds the focus, which means you purposely lose out on any sort of cinematic depth. After using the ROG Delta II Tri-Mode Wireless Gaming Headset for dozens of hours across a couple of weeks we found that we barely - if ever - adjusted the equalizer, as ASUS's presets were excellent. This is always a good sign, because as much as we like tinkering with audio, plug-and-play is always the way to go with something so versatile.
The ROG Delta II is PlayStation 5 compatible, and testing it with Sony's excellent 3D Tempest Audio in Gran Turismo 7 and Horizon Forbidden West was just as impressive as pairing it with a range of PC games. The sound profile is best described as crisp and clear without sounding muddy or distorted even when experienced at high volume. Channel separation is also excellent with everything given room to breathe - whether that's sound off in the distance or around the corner in a game or a specific musical instrument being played listening to music.
Microphone Quality
With the ability to connect to a Bluetooth device in addition to a PC or gaming console, the ROG Delta II Tri-Mode Wireless Gaming Headset's microphone is more than up to the task. The microphone sound quality is decent enough to capture both vocal clarity and depth with some great noise cancellation for background sounds. Compared to similarly priced wireless gaming headsets it's one of the better ones that we've tested and a testament to the ROG Delta II's design. It's not quite broadcast quality, but it's able to capture enough depth and detail that it's one of those headsets where you'll get asked 'hey, what microphone are you using?'
Final Thoughts
ASUS's ROG Delta II Tri-Mode Wireless Gaming Headset is not only a premium gaming audio product, but one that seemingly covers all bases. Crisp, detailed, high-resolution audio? Check. Comfortable lightweight fit that can be worn for hours? Check. Great-quality microphone for chat, with the ability to connect to multiple devices and take call when you're gaming? Check. It even has a long-lasting battery with excellent customization options on PC, but it is more expensive than some of its gaming headset contemporaries.

One of the only other downsides is that Xbox compatibility is limited to a wired connection on account of Xbox wireless audio being its own thing. Pricing aside, when it comes to versatility, comfort, and features it's hard to look past the ROG Delta II Tri-Mode Wireless Gaming Headset. We were able to tune and tweak the audio for excellent results for gaming, watching movies, listening to music, and even jumping into a Discord group chat. And really, when you pair that with a physical design that delivers all-day comfort, the ROG Delta II Tri-Mode Wireless Gaming Headset becomes an easy recommendation.
