The Sony WH-1000XM4 headphones are renowned for their exceptional sound quality, noise cancellation, and comfort. They are a popular choice for audiophiles and everyday users alike. However, some users have reported encountering a frustrating issue: the headphones pair successfully with their Windows 10 computer, but the connection fails to establish, preventing audio playback or microphone use. This article aims to provide a comprehensive guide to troubleshooting this specific problem, offering a range of solutions to help you get your WH-1000XM4 headphones working seamlessly with your Windows 10 system.

Understanding the Problem

Before diving into solutions, it's important to understand the possible causes of this pairing but no connection issue. Several factors can contribute to this problem, ranging from simple configuration errors to more complex driver or software conflicts. These include:
