Boya 2.4 GHz Dual Lavalier Microphone Wireless BY-WM4 Pro-K3 for iOS

Boya's WM4 Pro-K3 is an inexpensive station set for recording sound during presentations, interviews and conversations with your iPhone. The transmitter and receiver of the WM4 Pro are very compact and connect to each other on the 2.4 GHz frequency. You simply connect the receiver to your iPhone or iPad using the (MFi) Lightning port. You do not need a cable for this, because the receiver of the BY-WM4 Pro-K3 is connected directly to your iPhone/iPad.

Differences from the WM4

The WM4 Pro is the successor to the WM4 and features a higher signal-to-noise ratio, so you hear less background noise. In addition, the WM4 Pro is more compact than the WM4.

Application WM4 Pro

If you are looking for a basic transmitter set for easy voice recording with your iPhone or iPad, the WM4 Pro-K3 is a good choice. Optionally you can adjust the volume with the + and - button.

The range between the transmitter and receiver is up to 60 metres.
