Would this wireless microphone kit work for you? This one works with Smartphones, the DJI Pocket Osmo II and DSLR cameras. I made a minor tweak by adding Broadcast Compression (applied in Adobe Premier) and a tweak to the EQ at around 2.5kHz because my voice is quite deep. I always do that anyway. Just search for "Wireless Dual Lavalier Microphone, Comica BoomX-D2 2.4G Compact Wireless Microphone System with 2 Transmitter 1 Receiver". I like 🙂 Callum.
