Ugreen USB Audio Adapter includes a stereo headphone output jack and a mono microphone input jack. It can bypass the defective sound card or the faulty 3.5mm audio port of your laptop/desktop system and regain the audio function for you. Save the cost of replacing a failed sound card.
Meanwhile, some laptops or ultrabooks only combine headphone and microphone into one 3.5mm audio jack. With this usb Audio Adapter, your traditional headset could still be used on your laptops.
