Overview

The Razer Kraken Ultimate RGB USB Gaming Headset is built around THX 7.1 Spatial Audio technology, which goes beyond standard surround sound to deliver precise positional audio cues. For competitive gamers, this means being able to accurately locate opponents by sound alone, whether it's footsteps in an FPS or ability cues in a MOBA. The retractable boom microphone features active noise cancellation that filters out environmental sounds, ensuring clear communication with teammates even in noisy rooms. On-earcup controls let you adjust volume and toggle THX Spatial Audio on or off without tabbing out of your game.

Comfort is addressed with oval ear cushions infused with cooling gel, designed to prevent heat buildup during extended play sessions. The cushions also include indentations that relieve pressure for glasses wearers, a thoughtful detail for long gaming marathons. The ear cups feature Razer Chroma RGB lighting with support for 16.8 million colors, integrating with game events and syncing across a broad ecosystem of compatible hardware and smart lighting. As a USB wired headset, the Kraken Ultimate draws power and audio directly from the connection, which ensures consistent audio quality but limits compatibility to devices with USB ports. This renewed unit offers the full Kraken Ultimate experience at a reduced price point.
