The headphones may have been connected to the computer through Low Energy (LE) communication mode. This usualy occurs when the headphones are paired without pressing the Power button for seven seconds, and may result in the headphones not pairing to the computer or the computer not having sound.
To resolve the issue, make sure to press the Power button on the headphones for seven seconds to put the headphones in pairing mode before you pair the headphones with the computer.
After the headphones are in pairing mode, both WH-1000XM4 and LE_WH-1000XM4 appear on the computer screen. LE_WH-1000XM4 may appear first, and then a few seconds later WH-1000XM4 will appear. Wait for WH-1000XM4 to appear on the computer screen, then select it.
- LE-WH-1000XM4 will no longer appear after upgrading to firmware version 2.0.7 released on 5th November 2020.
- It may take up to one minute before WH-1000XM4 appears.
- If you want to connect the headphones to two devices simultaneously (multipoint connection), open the Sony | Headphones Connect app and turn on Connect to 2 devices simultaneously. Even though LE_WH-1000XM4 may appear first, it is important that you wait for WH-1000XM4 to appear on the device screen, then select WH-1000XM4.
