The white A50 Xbox One Headset has been released in the United States. Astro Gaming previously released the black and Halo (which is based on the popular first-person shooting franchise that includes the recently-released Halo: The Master Chief Collection and the upcoming Halo 5: Guardians) editions of the same product. You can purchase the white version with this page from the Amazon website.
In case you haven’t been paying attention, the A50 Xbox One Gaming Headset uses what is advertised as “cutting edge wireless Kleernet 5.8ghz technology.” You will have the ability to choose from three different EQ modes for listening. Moreover, the unidirectional microphone is also designed to better distinguish you voice from the background noises. The product is also light in weight and can be adjusted to fit your head, providing some comfort during extended play time.
