Price and Availability
The ASUS ROG Delta II may vary in price just slightly depending on where you buy it from, but from official retailers like ASUS, Best Buy, or Amazon, it will generally set you back about $230. It comes in white or black and includes all of the accessories needed to access its full functionality, including a USB-C charging cord, detachable microphone, 3.5mm audio cord, a USB dongle, and a second pair of earmuffs.
A Functional Design With Some Minor Comfort Concerns
Overall, the ROG Delta II is a functionally well-designed headset. The detachable mic slot is shaped so you always know which way to put it. The earpieces can be extended or retracted into the headband for easy adjustment. All of the buttons are on the rear of the earpieces, which feels more natural to me, personally. The design is simple and straightforward: the controls for 2.4GHz connection and the mic are on the left side, and the Bluetooth controls are on the right.
There are only a few button combinations you need to learn to fully control the headset with the two buttons, two dials, and one switch it sports. If nothing else, it’s effectively foolproof and won’t be difficult for anyone to use. Overall, the Delta II is relatively comfortable, with two different earmuffs included, made of different materials, so you can pick the one that feels best to you. It’s also fairly lightweight and clutches the head well, unless you lean at a nearly 90-degree angle.
Despite this, the headband can get a little uncomfortable on the top of your head when wearing it for extended periods of time, at least for me personally. On the other hand, my dad thinks they are more comfortable than his headset, so it’s really a matter of personal opinion. That said, if comfort for long gaming sessions is your highest priority, I actually think the ROG Pelta headset, which is significantly cheaper, is a better choice.
Overall, the Delta II is a very good headset that is fairly comfortable with a functional design.
Punchy Sound Quality That Hits Above Its Weight Class
For a cheapskate like me, $230 seems like a lot for a gaming headset, but the ROG Delta II is technically a mid-range option. At this price point, the audio quality is very good. The headset sports 50mm titanium-plated diaphragm drivers with a 20 Hz–20 kHz range, offering crisp, distortion-free audio that captures every footfall in a quiet RPG and accentuates every bombastic explosion in a shooter.
It’s easily comparable to higher-end gaming headsets that could cost you upwards of $300, and with the ASUS Armoury Crate software, you can adjust all sorts of audio settings and tweak the Delta II to sound exactly how you want. Though the drivers are the same as the ones used in cheaper headsets like the ROG Pelta, the Delta II has crunchier bass that accentuates deep sounds better, but the customization options ensure you can put the focus on whatever aspect you want.
Either way, every game I played during my time with the ROG Delta II sounded great, and I never had issues hearing my teammates clearly, or them me. The 10mm super wideband boom microphone can pick up even the slightest sounds, so you don’t have to shout into it to get your message across. Of course, your buddies might hear you chomping on some chips during the game, but there are settings you can modify to counter that.
That said, bear in mind that the audio and call quality may vary slightly depending on what mode you are using: there is generally more latency in wired and Bluetooth mode than there is in 2.4GHz mode. That said, you probably won’t notice a difference unless you’re a serious audiophile, and as far as being used on different platforms is concerned, I noticed no difference between my Xbox Series X, PC, smartphone, or Steam Deck.
Enough Battery Life to Beat Any RPG in One Sitting
I do not recommend playing any game for 110 hours straight. But if you ever wanted to do something that insane, a fully-charged ROG Delta II could carry you to the finish line without ever needing a recharge, though that depends on how much you value your aesthetic. Because honestly, it’s the RGB lighting that drains all the power from the Delta II. Even in 2.4GHz mode, the most demanding, the Delta II can last 110 hours without the RGB lighting. But with the lighting, this drops to only 24 hours.
It can last even longer in Bluetooth mode, with about 140 hours of lifetime with the RGB off. But don’t worry too much about it if you love your RGB lighting: the Delta II charges very quickly, easily gaining several hours of life from just ten or fifteen minutes of charging. You’ll never need to worry about it dying on you mid-game session unless you forgot to charge it for even half an hour on any given day.
The Competition
If you’re dead set on getting a ROG gaming headset, the Delta II is one of the more expensive options, especially compared to its companions, the ROG Pelta. The Delta II is a lot more expensive than the Pelta, being $230 compared to about $130. The Pelta is another headset I’ve reviewed, and it’s great for the price. It’s actually even more comfortable than the Delta II thanks to its elastic headband.
However, the Delta II has better overall sound quality with a much beefier bass, even though the Pelta still has great audio. The biggest difference between the two is the fact that the Delta II has dual Bluetooth connectivity, allowing it to connect to two devices at once and play audio from them simultaneously. The Delta II also has a 3.5mm wired connection, meaning it can connect to Xbox consoles, which the Pelta can’t.
As for other headsets in the same price range from other brands, the Delta II is definitely comparable in quality, but you’ll probably want to do a bit more research on each of them to find out what’s best for you first.
Should You Buy the ROG Delta II?
Ultimately, the ASUS ROG Delta II is a very good gaming headset. Its capabilities don’t fall short of the $230 price tag: it feels good, sounds good, and looks good. That said, whether or not it’s worth it depends on just what you want out of a gaming headset, as you can still find cheaper gaming headsets that are about the same quality in those same areas, like the ROG Pelta.
However, the Delta II does have a few unique features that may be worth the increased price, such as the ability to connect to two devices at once and the presence of a wired 3.5mm connection. Therefore, it may be worth it if those features are crucial to you. All in all, the Delta II doesn’t disappoint at its current price point, but there are also comparable quality headsets at somewhat cheaper prices, so it’s really down to what you value most in a gaming headset.
Of course, if you’re on the lookout for great audio in your video game sessions, you could always consider getting a standalone pair of headphones and a mic instead.
