The ASUS ROG Delta II is a tri-mode wireless gaming headset in black, sitting above the ROG Pelta in ASUS's ROG audio range with a longer-rated battery and the same SpeedNova low-latency wireless technology. It offers Bluetooth, 2.4GHz wireless and 3.5mm wired connectivity, giving flexibility across PC, console and mobile devices from a single headset. 50mm titanium-plated diaphragm drivers handle audio duty, paired with a 10mm super-wideband boom microphone for clear voice capture during chat and streaming. ASUS rates the battery at up to around 110 hours per charge, among the longest in its class, reducing how often it needs to come off the charger during regular use. At roughly 318g it remains light for extended sessions, and ROG's DualFlow Audio and Aura Sync-compatible RGB lighting round out a headset aimed at players who want ASUS's top-tier wireless audio feature set.
