The Wireless GO II, a popular dual-channel wireless microphone system, now has a single set option: the "Wireless GO II Single," which includes one receiver and one transmitter. This single set retains all the features of the Wireless GO II, including high-quality recording with the transmitter's built-in microphone, versatile output options compatible with cameras, computers, and smartphones, an improved transmission distance of up to 200m with enhanced stability, and onboard recording functionality that can be switched via a dedicated app. It's perfect for casual vlogging or situations where a single microphone is sufficient. I purchased this, but I haven't used it much. 【Specifications】 Transmission Frequency: 2.4GHz Transmission Distance: Approximately 200m (line of sight) *May be shorter depending on the environment.
