The Sony PlayStation PULSE 3D wireless headset is completely different from Sony’s head-mounted headset in appearance. The overall design style is very integrated with the PS5, and it also uses black and white colors. The headphone beam has a unique curve, and the inner side is equipped with a suspension elastic cushion to improve wearing comfort. The headset supports two ways of using a wireless adapter and a 3.5mm audio cable, and supports 12 hours of battery life.
The PS5 host has made targeted optimizations for Sony PULSE 3D wireless headset, so that it can present the 3D sound effects achieved by the PS5 host, and provide players with an immersive game audio experience. Sony PULSE 3D is also equipped with dual noise reduction microphones to ensure clear communication with teammates during the game. Convenient control functions support microphone mute, volume, sound effect adjustment, and test whether your voice is transmitted to teammates’ microphone monitoring, etc.
