Presented as a set of two, the Saramonic SR-U9-MC1 Lavalier Microphone Clips can replace worn lav clips or serve as backup in case any other lav clips break on location. With durable metal construction and an alligator-style mechanism, the SR-U9-MC1 securely attaches to clothing. Its 7mm internal diameter makes it compatible not only with standard 7mm diameter lapel mics, but also most Saramonic lavalier microphones such as the SR-M1, SR-UM10-M1, SR-UM9-M1, WM4C-M1, LavMicro Series, SR-ULM10 Series, and LavMic Series.
