The Kraken V4 is Razer's wireless gaming headset combining 2.4GHz low-latency gaming audio, Bluetooth convenience, and USB wired versatility in a single device. Remanufactured units offer the same TriForce drivers, THX Spatial Audio, and 9-zone Chroma RGB at a lower price point than new, making them a practical choice for gamers who want high-end wireless audio without paying full retail.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eTriForce Titanium 40mm drivers with 20-28,000Hz frequency response:\u003c\/strong\u003e\u003c\/p\u003e\n\n\u003cp\u003eRazer's patented TriForce Titanium 40mm drivers use a 3-part driver design that divides the sound spectrum into distinct highs, mids, and lows, tuning each independently. This separation delivers clear, detailed treble, full midrange vocals and effects, and deep bass impact in a single 40mm unit. The 20-28,000Hz frequency response extends beyond the standard 20-20,000Hz range, capturing additional high-frequency detail in game audio and music. Four onboard audio profiles (Game, Movie, Music, Custom) allow quick switching to suit different content.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003e3 connectivity modes with SmartSwitch Dual Wireless:\u003c\/strong\u003e\u003c\/p\u003e\n\n\u003cp\u003eThe Kraken V4 connects via Razer HyperSpeed Wireless (2.4GHz USB-C dongle with 20ms ultra-low latency), Bluetooth 5.3 (AAC and SBC codecs), or USB wired via the included USB-C to USB-A cable. SmartSwitch Dual Wireless allows simultaneous 2.4GHz and Bluetooth connections: take an incoming Bluetooth phone call without disconnecting from your game audio, then return to gaming when the call ends. The compact USB-C dongle connects directly to PC, PlayStation, Nintendo Switch, and Steam Deck, with a USB-C to USB-A adapter included.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003e70 hours battery, THX Spatial Audio, and 9-zone Chroma RGB:\u003c\/strong\u003e\u003c\/p\u003e\n\n\u003cp\u003eThe battery provides up to 70 hours of continuous playback with RGB lighting disabled, or up to 35 hours with the 9-zone Razer Chroma RGB lighting active. A 15-minute quick charge delivers 6 hours of playback when time is short. THX Spatial Audio provides 7.1 surround sound with realistic positional audio, and over 60 custom-tuned THX Game Profiles optimise the soundstage for specific game titles. Each earcup features 9 individually customisable RGB lighting zones configured through Razer Synapse.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eRetractable Super Wideband microphone and breathable mesh comfort:\u003c\/strong\u003e\u003c\/p\u003e\n\n\u003cp\u003eThe retractable Razer HyperClear Super Wideband microphone captures voice with a 10-10,000Hz frequency range at a 32,000Hz sampling rate, delivering clear, natural voice quality for team communications.
