The DifferenceThe NexiGo N960E Pro is the world's first webcam designed to meet all your connectivity needs for conference calls. With dual USB and audio ports, it eliminates cluttered cables and expands device compatibility. Its innovative passthrough technology allows seamless integration of additional equipment, such as microphones and keyboards. The 3.5mm audio jack ensures clear audio through speakers or headset, regardless of your computer's audio capabilities. Three-Level Adjustable Ring Fill LightThe built-in ring light provides 3-light Modes (with simple touch) and stepless adjustable brightness (with touch and press). You can achieve your ideal brightness level by touching and holding the ring light in dim light environments. Brighter than many other webcams with built-in lights, the light has a soft tone so that it doesn't create a glare.
