Saramonic Blink 500 RXDi 2.4GHz Lightning Microphone

Compact Lightning dual-receiver for iOS

The Saramonic Blink 500 RXDi is a 2.4 GHz wireless microphone receiver that plugs straight into an Apple Lightning port. It targets vloggers, journalists and mobile creators who need broadcast-quality sound without cables or batteries. The ultracompact black unit draws power from the iPhone or iPad, so it is ready whenever the iOS device is charged.

Dual-channel 2.4 GHz reception

The receiver pairs with up to two Blink 500 TX transmitters, giving you two independent audio sources on a single Lightning connection. Intelligent channel-hopping keeps the 2.4 GHz link stable in crowded RF environments, while the direct digital path avoids analogue noise. Range and latency limits are defined by the 2.4 GHz band and the paired transmitters, not by the receiver alone.

No bundled transmitters or charging accessories

The box contains only the Lightning receiver; Blink 500 TX microphones are sold separately, so you must purchase one or two transmitters to capture any sound. Because the RXDi has no internal battery, it adds no charging steps but does consume the host device’s power during long sessions. A Lightning-equipped iPhone or iPad running a compatible iOS version is the only other requirement.
