Sony updates gaming mode for WH-1000XM6: Reduces latency to under 40ms.
Sony has just released a major firmware update for its WH-1000XM6 headphones, adding GMAP audio profiles that help reduce latency to extremely low levels, optimized for professional gaming needs.
Sony has officially released a major software (firmware) update for its two highest-end headphone lines, the WH-1000XM6 and WH-1000X The ColleXion. The biggest highlight of this upgrade is the introduction of Gaming Mode, a feature designed to completely solve the audio latency problem on wireless devices.
Enhance your audio experience with Bluetooth LE Audio.
According to Sony, firmware update version 3.1.5 for the WH-1000XM6 and version 1.3.0 for the WH-1000X The ColleXion are now available through the Sony Sound Connect app. Users can easily install it by accessing the headphone settings within the app.
The core feature of this update is support for Gaming Audio Profile (GMAP) based on the Bluetooth LE Audio standard. This is a significant step forward compared to traditional Bluetooth connections, which often suffer from latency limitations resulting in inconsistent audio and video when playing high-speed games.
Technical analysis: How does latency under 40ms work?
According to Bluetooth SIG standards, the GMAP profile is designed to maintain extremely low overall audio latency. Specifically, the specifications are strictly defined to ensure a seamless experience for gamers:
| Processing components | Standard latency (milliseconds) |
|---|---|
| Wireless transmission | 30 ms |
| Audio processing on headphones | 10 ms |
| Total system latency | Under 40 ms |
In addition, GMAP ensures synchronization between the left and right channels with a deviation not exceeding 100 microseconds. This helps maintain accurate sound space, assisting players in more effectively locating opponents in games.
Flexible signal configurations
GMAP offers four different signal profiles, categorized from A to D, allowing the system to self-adjust based on speed or stability priorities:
- Configuration A:Prioritize maximum speed, striving for latency levels even lower than 30ms.
- Configuration D:Focusing on stability, suitable for environments with high levels of electromagnetic interference, avoiding audio interruptions.
Advantages of common standards over proprietary technology
The biggest difference between GMAP and gaming modes developed by headphone manufacturers is its openness. Because GMAP is part of the standardized Bluetooth technical specification, it allows devices from many different manufacturers to interact seamlessly.
However, users should note that to take advantage of this technology, both the audio source (such as a phone, tablet, or computer) and the headphones must support the Bluetooth LE Audio standard and the corresponding GMAP profile. Sony's pioneering integration of GMAP into flagship models like the WH-1000XM6 demonstrates the company's efforts to blur the lines between dedicated music headphones and professional gaming headphones.
