About the QED QE7821
From our tech experts at CEN
The QED Performance QE7821 is a 0.6m USB Type A to USB Type C cable for audio and data. It connects a device with a standard USB-A port to one with a USB-C socket, and is the shorter of the two USB-A to USB-C lengths in the QED Performance range.
Who it suits
The 0.6m length suits short desk connections, such as a computer USB-A port to a USB-C DAC or portable player sitting right beside it, where a longer lead would just coil up. If the devices are further apart, the 1.2m QE7824 gives more reach.
Our tech experts advise
Check which end each device needs: USB-A is the larger rectangular plug, USB-C the small oval one. Plug straight into the computer rather than a hub for the steadiest connection. Avoid sharp bends at the plug when the device sits close by. See the range in our QED collection.
