Yes, in order to utilize the Lavalier GO microphone with a smartphone or tablet, it is necessary to use a TRS to TRRS adapter such as the RØDE SC4. This requirement arises from the fact that most mobile devices possess a TRRS input, which is incompatible with the Lavalier GO's TRS output.
Moreover, for devices that doesn't have a native 3.5mm port and have a Lightning or USB-C port, an additional 3.5mm to Lightning/USB-C adapter is also required.
For a simplified setup with more features and better sound quality, we recommend using the AI-Micro to connect any microphone with a 3.5mm output to your phone or tablet, including the Lavalier GO.
