Razer Kraken V4 Remanufactured Wireless Gaming Headset with TriForce 40mm Drivers, THX Audio, and 70hr Battery
Remanufactured Razer Kraken V4 restored to full working condition:
This Razer Kraken V4 is a remanufactured unit, professionally inspected and restored to full working condition. 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.
TriForce Titanium 40mm drivers with 20-28,000Hz frequency response:
Razer'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.
3 connectivity modes with SmartSwitch Dual Wireless:
The 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.
70 hours battery, THX Spatial Audio, and 9-zone Chroma RGB:
The 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.
Retractable Super Wideband microphone and breathable mesh comfort:
The 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. The microphone retracts flush into the earcup when not in use for a clean look during music listening and commuting. The breathable mesh fabric earpads with memory foam keep ears cool during extended sessions, and the 350g weight sits comfortably during long gaming or work-from-home days.

Setup and Care
Initial charge and connectivity setup:
Charge the headset fully via the USB-C to USB-A cable before first use. For 2.4GHz wireless gaming, insert the USB-C HyperSpeed dongle into your PC, PlayStation, or Steam Deck (use the USB-A adapter if needed). The headset pairs automatically with the dongle. For Bluetooth, press and hold the multi-function button for 7 seconds to enter pairing mode, then select Razer Kraken V4 from your device's Bluetooth settings.
Installing Razer Synapse and configuring audio profiles:
Download Razer Synapse 4 on your PC for full access to EQ customisation, THX Spatial Audio settings, Chroma RGB lighting configuration, and microphone settings. Select from 4 onboard audio profiles (Game, Movie, Music, Custom) by tapping the multi-function button on the headset. Enable THX Spatial Audio for 7.1 surround sound and browse the 60+ custom-tuned game profiles for positional audio tuned to specific titles.
Using SmartSwitch Dual Wireless and the retractable microphone:
With SmartSwitch enabled, the headset maintains both 2.4GHz and Bluetooth connections simultaneously. An incoming Bluetooth call automatically pauses game audio and routes the call to the headset; game audio resumes when the call ends. Pull the microphone down from the left earcup to extend it for team chat, and push it back flush into the earcup when not needed.
Care and storage:
Store the headset in a cool, dry place when not in use. Wipe the earpads and headband with a soft, dry cloth. Avoid exposure to excessive moisture. Keep the USB-C charging port clear of dust and debris. Charge the battery periodically even during extended periods of non-use to maintain battery health. The memory foam earpads are not user-replaceable on the standard V4 model.
