Desktop Computers: Rear Ports Are Preferred
USB ports on desktop computers fall into two categories: front-facing and rear-facing.

• Rear PC Ports (Recommended): These ports are soldered directly onto the motherboard. This results in a shorter signal transmission path, stable power delivery, and strong resistance to interference. During voice calls, this effectively prevents background electrical hum and microphone static. Note: Occasionally, a USB headset may fail to function when plugged into a front port but will work normally once connected to a rear USB port.
• Front PC Ports: For the sake of convenience, you may certainly use the front USB ports; generally, this poses no significant issues. However, because these ports connect via internal chassis cabling, they are susceptible to electromagnetic interference from components such as the power supply and hard drive. This interference can potentially lead to issues such as intermittent audio, echoes, or the headset failing to function altogether.

Laptops: Any Port Works

• On laptops, all USB ports are integrated directly onto the motherboard. The internal wiring paths are relatively short, meaning there is negligible difference in performance regardless of whether the port is located on the front, rear, left, or right side of the device. You may simply plug your device into any available port for normal operation.
