### ⭐⭐⭐⭐⭐ DJI Action 5: Adapter comparison with stereo mikes
*by A***R on October 31, 2024*

I have tested several USB-C microphone adapters with the DJI Action 5 camera, and this adapter is my preferred pick. My main requirement was that the adapter supports STEREO (many adapters mix stereo microphone signals to mono). A secondary requirement was that the adapter has a 3.5mm male plug that can plug directly into the mike (versus a female 3.5mm plug that requires an additional 3.5mm male to male cable). The mikes I used were the ZENIKO OC-D1, Comica Traxshot and the Comica Traxshot Pro - all of them have a 3.5mm female plug for audio output but the Traxshot Pro also supports USB-C audio output - no adapter needed !.Adapters tested:DJI Mic adapter (ASIN: B0C783X6CD): Adapter works but it is expensive and bulky (could potentially get knocked out of the action camera and get lost). Recorded audio is not as loud (the adapter is meant to be used in loud environments) and you might have to increase the gain in the camera settings which will increase the noise floor.BOYA by-K2: [This item] Meets all requirements. Good sound quality.Hollyland 3.5mm TRS Male to USB Type C (ASIN: B0B4W8WB7L): I liked the coiled, spiral cable, but adapter is mono.Saramonic SR-C2001 (ASIN: B08KHD1S7S): The Saramonic adapter is very similar to this adapter but the left and right channels are REVERSED [did someone not test this when they designed the adapter ????]Saramonic SR-C2003 (ASIN: B08DTP7R8M): Adapter works but it has a female 3.5mm plug. Left/right channel layout is correct.Comica 3.5mm TRS to USB-C (ASIN: B0C8MBNG4G): Mono only.-------Summary: If you have a mike with a female 3.5mm plug, buy this adapter. If it has a male 3.5mm plug, buy the Saramonic SR-C2003. Both adapters will give you good audio on a DJI Action 5.-------

### ⭐⭐⭐⭐⭐ Works on DJI action 3!!
*by C***N on April 2, 2025*

This is the third cord I've tried, and I went into it skeptical. I needed it to connect my dji action 3 camera to my dji mic mini wireless mic setup.. This cord works great, audio comes thru loud and clear, and is the perfect length for my camera cold shoe mount to the usb c on the side!

### ⭐⭐⭐⭐⭐ Great wire
*by L***R on March 19, 2025*

Works as intended. Not a super high quality wire but there is no interference that I've encountered
