Hollyland Genuine 3.5mm TRS-TRRS Conversion Cable for Smartphone Connection This conversion cable is used to connect the receiver of Hollyland wireless microphone systems to the headphone jack of smartphones and tablets for recording. It converts the 3-pole (TRS) output from the microphone side to the 4-pole (TRRS) input signal on the smartphone side. It is equivalent to the accessories included with the Lark 150, Lark M1, etc., and offers the peace of mind that comes with genuine products. The plug shape is a 3.5mm L-shaped plug on both ends. The black plug is TRS (3-pole) for connection to the microphone receiver, and the gray plug is TRRS (4-pole) for connection to the smartphone. The cable is a stretchy curly cord, making it convenient as the wiring won't get in the way during shooting with a gimbal or selfie stick. The total length when contracted is approximately 11cm. It is in unused condition with the tag attached, and the terminal plating is also clean. Please note that if you are using it with recent iPhones or Android devices that do not have a headphone jack, you will need a separate Lightning or USB-C adapter. #Hollyland #Hollyland #Lark150 #LarkM1 #ConversionCable #TRRS #SmartphoneMicrophone #AudioCable #ExternalMicrophone #VideoRecording
