Now we have crystal-clear gaming audio, but the goal was to develop a great headset for console and living room, so removing cables was paramount. But with anything wireless, latency and reliability are always a concern, as any small interruption will undermine the experience. The wireless transceivers need to fulfill a few criteria:
1 As much as possible audio should be transferred as “lossless” to not diminish the quality in any way. The Razer Thresher Ultimate employs a chip that transmits the audio uncompressed, which can provide lossless audio in a good environment. If there’s interference from other sources, the algorithm automatically prioritizes core audio to ensure you get all sounds and only cuts off fine details, so you’ll never completely lose out on audio.
2 The 2nd equally important criteria is latency. With wireless you need to pay a certain price for latency compared to wired, but the goal is to achieve a latency that’s not perceptible to the human brain. The Razer Thresher Ultimate operates at less than 1/6th of Bluetooth Latency. To be imperceptible, it’s commonly understood that latency must be below 20 ms.
3 Lastly vulnerability to interference or wireless noise must be minimal. Think of wireless waves like ripples in the water. Unrestricted, the waves clearly emanate from the location and spread out evenly. However, once they bounce back from a wave-reflecting surface (a large metal surface, for example) these ripples can overlap each other and create noise leading to small temporary deadspots in the room. To avoid that, the Razer Thresher Ultimate utilizes a Dual Antenna system, constantly evaluating signal strength at each antenna and choosing the better one. The antennas are placed facing away from each other to always have at least one antenna with a strong connection. Walking around the room or sudden head turns will not cause any drops in transmission, and keeps your audio going even when moving around.
