Boya BY-WM4PRO K1 Wireless Microphone system 2.4G (1 Transmitter)

The Boya BY-WM4PRO K1 wireless microphone system 2.4G (1 transmitter) is a handy sound recording set for presentations, interviews or other conversations. The K1 comes with one transmitter, one receiver and one lavalier microphone. The transmitter and receiver interconnect on a 2.4 GHz frequency, at a maximum distance of 60 meters. You connect the receiver to your smartphone, camera or laptop with the included 3.5 mm TRS or TRRS cable. If your device does not have a 3.5 mm input, you can use an adapter (not included).

The WM4PRO is the successor of the WM4 and has a higher signal-to-noise ratio. This means you have fewer problems with background noise. Wind noise is prevented with a wind jammer. The microphone can be attached with the supplied tie clip. The PRO is more compact than its predecessor. That makes it an ideal set to use on location.
