Best Performance

Another very good standard sound. I chose to connect to 2.4 GHz to test the stability of the signal. Personally, I think the results are excellent. There are no interruptions or sound drops. The sound is booming when playing games. As for listening to music, there is a fair amount of bass, not too much to be annoying. The mid-range is good, but we can adjust the EQ to help.

All-round PC recommendation

The ROG Delta II is the perfect gaming headset for anyone who attaches particular importance to the feature of simultaneous Bluetooth audio playback, which is becoming increasingly popular but has never been implemented in such a sophisticated way.

Revolutionary Gaming Immersion

The ROG Delta II features tri-mode connectivity and is primed for competitive gaming with its ultra-low latency 2.4 GHz connection. It features 50 mm titanium-plated diaphragm drivers, delivering authentic and balanced audio to enrich gaming and other experiences. For team-based gaming, the 10 mm super-wideband boom microphone ensures you’re heard clearly even in the most intense firefights. Additionally, DualFlow Audio technology allows you to listen to two connected sources simultaneously – and even answer mobile calls by simply pressing a button on the earcup, so you won’t miss a beat.

50 mm Titanium-Plated Diaphragm Driver

Refined Wireless Sound Signature

The specially tuned sound signature1 of the ROG Delta II ensures what you hear is as close as possible to the original. You can experience incredibly authentic and balanced in-game sound, enhanced by an LC3+ codec2 with wide 20 Hz–20 kHz frequency response, which offers deep, powerful bass and crisp, clear highs. And with virtual 7.1 surround sound, every footstep, reload, and gunshot is amazingly lifelike. It also enhances positional and spatial audio to make gaming, music, and movie experiences incredibly phenomenal.
