ASUS ROG Delta II

Overview

The ASUS ROG Delta II is a flagship wireless headset built for competitive gaming and multi-platform versatility with tri-mode connectivity and DualFlow Audio technology. Released in September 2024 at $229.99, it positions itself as a premium alternative to SteelSeries and Logitech flagships with superior battery endurance. At 318g with 110-hour battery life and 50mm titanium drivers, it’s one of the longest-lasting wireless headsets available.

Key Features

DualFlow Audio Technology: Simultaneously connects to 2.4GHz and Bluetooth devices with independent volume controls, allowing you to take calls without pausing gameplay.

110-Hour Battery Life: Industry-leading endurance provides 110 hours in 2.4GHz mode or 140 hours via Bluetooth with RGB off. Fast charging delivers 11 hours from a 15-minute charge.

50mm Titanium-Plated Drivers: Harman-tuned sound signature delivers analytical audio with excellent positional accuracy for competitive FPS gaming.

ROG SpeedNova Wireless: Ultra-low latency 2.4GHz connection is 27% faster than competitors, ensuring perfectly synced audio for competitive play.

Dual Ear Cushion Options: Includes both PU leather pads for noise isolation and breathable mesh fabric pads for extended comfort.

Audio Quality

The 50mm titanium-plated drivers follow Harman tuning, delivering analytical sound suited for competitive gaming rather than bass-heavy entertainment. Controlled bass provides impact without overwhelming mids, while crisp treble avoids harshness during extended sessions. The 20Hz-20kHz frequency response supports Hi-Res 24-bit/96kHz audio in 2.4GHz mode, offering noticeably better clarity than standard Bluetooth codecs. The 32-ohm impedance makes it easy to drive across all platforms.

Soundstage width and positional accuracy excel in competitive FPS titles. Footsteps, gunshots, and reloads are distinct and directional, making it easy to pinpoint enemy locations in Valorant, Call of Duty, and Counter-Strike. The analytical tuning prioritizes detail retrieval over warmth, which benefits competitive players needing precise audio cues but may feel clinical to casual gamers preferring richer, more immersive sound signatures.

Comfort & Build

At 318g, the Delta II feels lightweight despite aluminum yoke construction. The D-shaped earcups measure 64mm height by 54mm width with 30mm depth, accommodating most ear sizes and glasses. Two sets of ear cushions are included: PU leather for noise isolation and mesh fabric for breathability. The memory foam headband padding is thin, which can cause pressure points during marathon sessions for users with larger heads. Clamping force is relaxed but secure.

Build quality combines plastic earcups with aluminum arms for a premium feel without excessive weight. Dual volume dials on each earcup control 2.4GHz and Bluetooth audio independently. RGB lighting rings the earcups with customization via Armoury Crate software. The detachable boom mic uses a standard 3.5mm connection with a locking mechanism.

Verdict

The ROG Delta II justifies its $229.99 price with exceptional 110-hour battery life, versatile tri-mode connectivity, and analytical Harman-tuned audio optimized for competitive gaming. DualFlow Audio’s simultaneous dual-device functionality stands out as genuinely useful for streamers and multi-platform gamers who need to manage calls and gameplay audio simultaneously. The titanium drivers deliver precise positional accuracy that benefits competitive FPS players, while fast charging and dual ear cushion options add practical value. It competes directly with SteelSeries Arctis Nova Pro and Logitech G PRO X 2 while offering significantly longer battery life.

Best suited for PC and PlayStation gamers who prioritize competitive audio precision and marathon wireless sessions. The analytical sound signature benefits FPS and MOBA players needing directional accuracy over immersive warmth. Xbox users are limited to wired connectivity. Casual gamers playing single-platform may find better value in mid-range options, but multi-platform users leveraging DualFlow Audio and tri-mode connectivity will appreciate the flagship feature set.
