The Razer Opus X is a wireless Bluetooth headset in a signature green finish, designed for those who need versatile audio across mobile devices, laptops, tablets, and the Nintendo Switch. It features 40mm custom-tuned drivers that deliver sound across a frequency range of 20 Hz to 20 kHz, while Hybrid Active Noise Cancellation helps block out environmental distractions. For moments when you need to hear your surroundings without removing the headset, the Quick Attention mode allows outside sound in with a simple press of the power button. Comfort is handled by plush leatherette ear cushions and an adjustable padded leatherette headband, paired with rotatable circumaural ear cups that provide a secure over-ear fit. You can manage your listening experience through the Razer Audio App or via the physical controls on the device, which include volume buttons and a multi-function center button. For gamers, a dedicated low latency mode reduces connection delay to 60ms, ensuring audio stays synced with the action. Battery life is substantial, offering up to 40 hours of playback when noise cancellation is off, or 30 hours when it is active. When power runs low, the headset recharges via a USB-C interface using the included 0.5 m cable. Built-in internal microphones make it easy to handle voice communications on the go, making this a practical choice for users who switch frequently between music, calls, and gaming.
