The Blink500 Pro B1 from Saramonic is a wireless transmitter set with built-in battery. The system consists of a transmitter and a receiver. You use the Blink500 Pro B1 with both smartphones and cameras, thanks to the included TRRS and TRS cable. A microphone is built into the transmitter, so you attach the transmitter to a piece of clothing with the clip and can immediately start recording. In addition, you can use the transmitter as a handheld microphone because it is a microphone and transmitter in one. A lavalier microphone is included for the transmitter. A lavalier microphone takes a little more time to pin on, but is less visibly present.
