ASUS ROG Delta II Wireless Gaming Headset Review: Premium Gaming Audio Done Right?

Wireless gaming headsets have become more competitive than ever. Modern flagship headsets now offer features that would have seemed excessive just a few years ago: simultaneous Bluetooth and 2.4GHz connectivity, ultra-long battery life, advanced software customization, and audio tuning that tries to bridge the gap between gaming gear and audiophile headphones.

The ASUS ROG Delta II is ASUS’ attempt to compete directly with premium gaming headsets from Logitech, SteelSeries, Razer, and HyperX.

Instead of focusing only on flashy RGB aesthetics, ASUS designed the Delta II around versatility, comfort, and high-end gaming performance. The headset introduces titanium-plated 50mm drivers, tri-mode connectivity, simultaneous dual-device audio, and battery life that easily rivals some of the best wireless headsets currently available.

Design and Build Quality

The first thing that makes the Delta II stand out is its distinctive triangular earcup design.

Unlike most gaming headsets that use traditional circular or oval earcups, ASUS kept the unique “Delta” series identity with sharp angular shapes and customizable RGB lighting on each side.

Surprisingly, the design feels less flashy in person than product photos suggest. The headset actually looks fairly clean and premium overall.

The build quality feels excellent.

The headset combines aluminum yokes, soft memory foam padding, leatherette materials, and a lightweight frame that feels premium without becoming excessively heavy.

Tom’s Hardware described the headset as “fairly lightweight” at around 318g, making it lighter than several competing flagship wireless headsets.

Comfort is one of the Delta II’s strongest features overall.

Tom’s Guide even described the headset as “insanely comfortable” thanks to its soft ear cushions and lightweight construction.

The headset also includes two sets of ear pads inside the box:

• Leatherette ear cushions
• Breathable fabric ear cushions

This is a surprisingly useful addition because users can choose between stronger passive noise isolation or cooler long-session comfort.

However, both Tom’s Guide and Tom’s Hardware criticized the ear pad replacement process for being unnecessarily awkward on a premium headset.

Some users also mentioned that the thin headband padding creates noticeable pressure on the top of the head during extremely long gaming sessions.

Still, for most users, comfort remains one of the best aspects of the headset.

Sound Quality

The ASUS ROG Delta II uses titanium-plated 50mm diaphragm drivers.

The headset aims for a more balanced and detailed sound signature rather than an aggressively bass-heavy gaming tuning.

That decision creates both strengths and weaknesses.

For gaming, the headset sounds genuinely excellent.

Tom’s Hardware praised the Delta II for its “detailed, precise, and well-layered sound,” especially during chaotic gaming scenarios with overlapping audio effects.

Directional audio is another major highlight.

Footsteps, gunshots, and environmental cues remain easy to track in competitive shooters like:

• VALORANT
• Counter-Strike 2
• Call of Duty: Warzone

Several Reddit users specifically praised the headset’s ability to track footsteps clearly during competitive gameplay.

The soundstage feels wide enough for immersive gaming, while the brighter treble tuning helps highlight positional audio cues effectively.

However, music performance is where opinions become more divided.

Tom’s Hardware criticized the headset’s bass response for feeling slightly underwhelming and described the overall music experience as somewhat “boring” without EQ adjustments.

PC Gamer also noted that the headset feels “a bit too flat” out of the box.

This means the Delta II is clearly optimized more for gaming accuracy than cinematic or bass-heavy entertainment.

Fortunately, the EQ customization inside Armoury Crate helps improve the experience significantly for users willing to tweak the audio profile.

Gaming Performance

The Delta II feels designed specifically for high-end gaming setups.

Everything about the headset prioritizes flexibility and gaming convenience.

One of the biggest standout features is simultaneous dual-device audio.

The headset can connect to both:

• 2.4GHz wireless
• Bluetooth

at the same time.

This means users can listen to game audio on PC while simultaneously taking Discord calls or listening to music from a phone.

Tom’s Hardware described this feature as one of the headset’s strongest advantages compared to competing gaming headsets.

In actual gameplay, wireless performance feels extremely stable.

Latency is low, connection reliability is excellent, and there are very few reports of major wireless instability.

Several Reddit users also praised the wireless range and overall connectivity reliability.

The detachable 10mm super-wideband microphone is another strong point.

Voice clarity sounds noticeably better than many gaming headset microphones within the same category.

Tom’s Guide specifically praised the microphone for sounding “loud and clear.”

For Discord calls, multiplayer communication, and even casual streaming, the microphone performs very well overall.

Battery Life and Connectivity

Battery life is one of the Delta II’s biggest strengths.

ASUS advertises up to 110 hours of battery life over 2.4GHz wireless with RGB lighting disabled.

Most reviewers confirmed that the headset easily delivers excellent real-world battery performance.

Several Reddit users also mentioned getting nearly a full week of gaming usage from a single charge.

The headset supports three connection modes:

• 2.4GHz wireless
• Bluetooth
• 3.5mm wired connection

This makes the headset extremely versatile across PC, PlayStation, Nintendo Switch, and mobile devices.

However, Xbox compatibility remains limited because the headset does not support Xbox Wireless directly.

Still, for PC-focused gamers especially, the connectivity options feel excellent overall.

Software Experience

The Delta II uses ASUS Armoury Crate for customization.

This is unfortunately one of the headset’s weakest areas.

Several reviewers and Reddit users criticized Armoury Crate for being overly complicated, buggy, or unreliable.

Common complaints include:

• Device detection issues
• Firmware update problems
• Random EQ resets
• Software instability

One Reddit user even mentioned that certain firmware updates noticeably changed the headset’s bass performance negatively.

Fortunately, many users also mentioned that the headset performs perfectly fine once configured properly.

Some users even recommended using the lighter “Armoury Crate Gear” version instead of the full software suite.

Downsides

Despite being a very strong overall headset, the Delta II still has several weaknesses.

The biggest issue is value.

At around $200+ depending on region and retailer, this is undeniably a premium gaming headset. Tom’s Hardware specifically questioned whether the headset competes strongly enough against rivals at its pricing level.

The stock sound tuning also feels somewhat restrained for music listening unless EQ adjustments are applied.

Some Reddit users described the sound as too flat compared to competitors like the SteelSeries Arctis series or Razer BlackShark lineup.

The Armoury Crate software ecosystem also remains frustrating for many users.

Finally, some users with smaller heads reported sizing issues due to the headset’s wider frame design.

Final Verdict

The ASUS ROG Delta II is one of the most feature-rich wireless gaming headsets currently available.

It successfully combines:

• Excellent gaming audio
• Strong positional accuracy
• Outstanding battery life
• Simultaneous dual-device connectivity
• Premium comfort
• Great microphone quality

into a very polished gaming-focused package.
