Razer Kraken X USB offers custom 40mm headphone elements that deliver clear and balanced sound from the quietest snooping tasks to the loudest explosions. Kraken X USB is equipped with high-quality 7.1 surround sound, which enables accurate and precise sound positioning in games. Thanks to its very light 275 gram design, the headphones feel comfortable even during long gaming sessions. Memory foam pads with spectacle channels provide ideal comfort and sound insulation from outside sounds. The padded headband reduces the pressure on the head, which further improves comfort. The microphone utilizes a cardioid directional pattern that reduces leakage noise from the sides and back of the microphone. Thanks to the cardioid microphone, you can hear without disturbing background noise. The volume control and mute button on the headphones make volume control easy. Enjoy crystal clear communication with a bendable cardioid microphone that utilizes a pick-up pattern which records sound from an extremely localized area in front of your mouth, while suppressing background noise from the back and sides.
