This adapter converts audio input devices that use a 3.5mm mini-jack (TRS) to the longer TRRS pin used by most smartphones. The lav mics that come with the Boya BF-WM8 system use a mini-jack. If you are looking for a lav mic specifically to use with your smartphone, we also carry the Boya BY-M1 which requires no adapter.
