As a ground-breaking wireless microphone kit, the BOYA BY-WM4 Pro Wireless Microphone system stands out from the outset. The design is still keeping the priority of functionality, and the company has gone one step further than other wireless mics on the market. Apart from offering dual-Channel for capturing audio with dual subjects to users' smartphones, tablets, DSLR cameras, camcorders, PCs, and so on, a set of different useful accessories, and up to 60m (197ft) operation range, the BY-WM4 Pro can be an expandable evolution system that allows the user to mix and match different kinds of receivers while using with the TX4 Pro transmitter.

There are three types of receivers offered in the BY-WM4 Pro series, including the RX4 Pro receiver, which comes with both 3.5mm TRRS and TRS cables so that it can be used with smartphones and cameras; the RXD receiver, with a lightning connector for iOS devices; the RXU receiver, which is designed specifically for Android and other devices with a Type-C jack. Since users can choose different receivers for their usage, regardless of whether they are using smartphones, cameras, or other devices, this concept is striking and significant. Moreover, this wireless microphone kit is really friendly to use, especially for RXD and RXU. Simply plug the receiver into your device, turn on the transmitter and receiver, and you're ready to go.
