When you think of Asus Republic of Gamers gear, you probably imagine neon-lit, Cyberpunk-esque motherboards, hefty GPUs, and blazing-fast monitors—but a headset? Not exactly top of mind, right? Well, let me introduce you to the Asus ROG Delta II—a gaming headset that not only surprises but might just bother some of the best gaming headsets of 2024.

At $229, the ROG Delta II offers a Tri-mode wireless setup that works across almost any device you own and can even connect to two simultaneously. The 50 mm titanium-plated drivers deliver premium sound, while the detachable boom mic ensures your teammates hear you loud and clear. There's also Aura RGB lighting for that signature ROG flair and a pretty astounding 110-hour battery life to keep you gaming all weekend without reaching for a charger.

Comfort is where the Delta II really shines. The headset comes with memory foam cushions in both pleather and breathable fabric options, which makes it easy to find the perfect fit. The generous earcups fully enclose your ears without adding pressure, and as someone who wears glasses, I was pleasantly surprised by how comfortable they are for long gaming sessions.

If I'm going to pick some nits, however, the headband, while padded and flexible, has a narrow design that occasionally causes some pressure on the top of my head. Fortunately, it's lightweight at just 318 g, so this really isn't a major issue.

In terms of design, this headset stays true to the ROG aesthetic, with triangular earcups and eye-catching RGB strips. The anodized metal arms holding the earcups add a premium touch, complete with “Republic of Gamers” branding. 

The ROG Delta II nails its controls with a minimalist yet intuitive approach. On the right earcup, you'll find a multi-function Bluetooth button and a dedicated volume dial for Bluetooth. On the left earcup, there's a power toggle for the 2.4 GHz connection, another volume dial, and a multi-function switch. Bonus: press the volume dial to mute the mic—no more awkward fumbling in-game.

Why separate volume controls? Because you can run simultaneous 2.4 GHz and Bluetooth connections. Imagine chatting with your significant other while grinding through Call of Duty: MW III with your squad. Both connections are rock-solid, with excellent range. Honestly, the 2.4 GHz connection is so good that wired setups really are starting to feel like overkill.

That said, if you still prefer the old-school approach, the Delta II plays nice with a bundled 3.5 mm aux cable, which is also how you'll connect to Xbox. Unfortunately, the USB-C dongle only supports PC, Mac, PS5, Nintendo Switch, and smartphones with a compatible port. Xbox's wireless limitations remain a bummer, keeping this from being the ultimate one-headset-for-everything solution.

On the mic front, it's detachable, so you won't look like a gaming nerd outside the house. The mic has a flexible gooseneck, comes with a pop filter, and even has an LED mute indicator. While the mic quality is solid, there are additional enhancements available through Armoury Crate for those who want extra control. Just make sure it's positioned correctly to avoid pop sounds.

Now, let's get into the real juice: sound quality. The Delta II's 50 mm titanium-plated drivers deliver crisp, detailed highs with minimal distortion. In practice, they sound great—though not quite on par with the Astro A50 X and its graphene drivers. That's arguably my biggest bugbear here, it's not quite hitting the heights of Logitech's tuning. Still, the sound profile is clean, precise, and yes, surprisingly flat for a gaming headset. There's no overblown bass or piercing highs, making it almost clinical, like an audiophile set of cans.

The Asus ROG Delta II gets an audio boost with the LC3+ codec and a frequency response of 20 Hz – 20 kHz, making it perfect for in-game sound separation. Gunshots, footsteps, reloads, and explosions are all distinct, which is crucial for competitive play. Positional accuracy is top-notch—I had no trouble pinpointing the direction of footsteps in CoD MWIII. In Diablo IV, every demon's cackle, coin drop, and the sweet chime of Legendary items was crystal clear amidst the chaos.

The immersive audio in story-driven games like Hellblade 2: Senua's Saga is where the Delta II shines. The unsettling whispers of the furies and the vast Viking landscapes felt eerily present.

But the headset didn't quite deliver when it came to music reproduction. Whether it was choral hymns, Hans Zimmer's epic scores, or hip-hop beats, the ROG Delta II's audio feels a bit too safe. Despite the clarity and separation, it lacks the punch that makes you want to groove. It has bass, but the tuning is too neutral for my taste. This is disappointing, especially since I love how comfortable these headphones are for all-day use. I kinda want to use them for everything, but they are absolutely best-suited to gaming over more general audio.

But, speaking of all-day use, the battery life is exceptional. With (the obviously needless) RGB lighting off, you'll get over 100 hours on a single charge, and a whopping 140 hours using just Bluetooth. It's only outdone by the HyperX Cloud Alpha Wireless at 300 hours. It's also worth nothing that fast charging gives you 11 hours of playtime from just 15 minutes of charging.

Overall, the ROG Delta II stands out for me with legendary battery life, superb comfort, and surgical sound for both casual and competitive gaming. While the tuning isn't perfect for music, a little EQ tweaking in Armoury Crate can help, though I'm definitely not a fan of the software itself. The only real downside is the price, but with discounts, snagging this for under $200 would make you feel like the gaming kid inside all over again.
