Razer is known for gaming audio peripherals; however, its new Anzu product is something else altogether. They are of the smart-glass type that incorporate personal speakers for the wearer's audio, which, as the OEM claims, will reach the user's head with reduced latency and increased immersion. They are available in Razer's store from now for US$199.99.
