Overview

The Razer Kaira (RZ04-03980100-R3U1) is a dual wireless gaming headset built around versatility and comfort. Its headline feature is Razer SmartSwitch, which enables seamless toggling between a low-latency 2.4GHz wireless connection for console and PC gaming and Bluetooth 5.0 for mobile devices. This means you can stay connected to your PlayStation game audio while simultaneously taking calls or listening to music from your phone — a genuinely useful feature for gamers who multitask. The TriForce 50mm drivers are engineered with separately tuned zones for highs, mids, and lows, producing audio that emphasizes clarity and separation across the frequency spectrum.

Comfort is addressed through Razer's FlowKnit memory foam ear cushions, which use a breathable weave to reduce heat and sweat buildup while maintaining a soft, low-pressure fit. The HyperClear Cardioid microphone features a bendable boom design with improved noise suppression from the back and sides, along with mic monitoring and game/chat balance controls. The Razer Audio app for Android and iOS adds EQ customization with four presets — including FPS Mode for competitive play and Bass Mode for immersive experiences — plus the ability to create fully custom profiles. With 30 hours of battery life, broad platform compatibility across PS5, PS4, PC, and Bluetooth-capable devices, and a lightweight build, the Kaira is designed for extended, multi-platform gaming sessions.

Key Features

TriForce 50mm Drivers: Cutting-edge drivers that can tune highs, mids, and lows separately—producing brighter, clearer sound with richer trebles and more powerful bass
