Headphones Won't Charge with a Third-party USB Cable
You might encounter difficulties charging your headphones using a third-party USB cable. We recommend using one of the following USB cables instead:
- The USB cable that was supplied with the headphones.
- A replacement Sony® cable from an authorized retailer.
- A fully connected standard USB cable.
Why Does It Matter What Type of Cable is Used?
There are USB cables promoted as For Charging Only. These cables have a reduced internal connection pattern in which the D+/- communication wires aren't connected.
For Bluetooth® and noise-canceling headphones, and for most other portable products, it is important that these communication lines are connected. Otherwise, it may not be possible to charge your device.
