Awards-5
Taiwan Excellence Awards 2025: 2025 Taiwan Excellence 2025 Taiwan Excellence Award ROG Delta II won the 2025 Taiwan Excellence Award, a world-renowed design award. Datormagazin Recommends: Asus ROG Delta II is a great option for those looking for really good wireless gaming headsets, whether for PC or PS5. 8/10: The ASUS ROG Delta II headset is a versatile and advanced headset that impresses with its wide range of features and solid comfort. 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.
Awards-6
80% Very Good: ASUS ROG Delta II is designed primarily for gamers whose priority is accurate information about what is happening in the game. They have great battery life on a single charge and offer great comfort for long periods of time. Excellent 5/5: For those of you who like my glorified RGB backlighting so much that you don't want to turn it off, I recommend deducting roughly thirty hours from the given figures. You would hardly find a gaming headset on the scene today with a longer battery life that will be able to provide you with such exceptional audio in games as the Delta II model does. 9.0 We Recommend: The Asus ROG Delta II are excellent gaming headphones and perhaps one of the most versatile headphones you can buy for a multimedia computer. They have excellent sound quality with good spatial perception for games, movies and music. They are comfortable to wear for long periods of time and look good. They are also worth it for virtual reality fans, as they are lightweight and compatible with PS VR2 and probably most other VR devices. Platinum: a gaming headset as it should be
