Hollyland Spares - 3.5mm TRS to USB-C (for Wireless Microphone Series)

The Hollyland 3.5mm TRS to USB-C Cable is an official OEM replacement and specialized analog-to-digital audio patch cord engineered for Hollyland’s flagship wireless microphone series.

Standard consumer USB-C cables or basic headphone adapters are built primarily for power delivery or listening. When a production crew tries to record audio using an unshielded or incorrectly wired cable, the camera or smartphone will often fail to recognize the microphone entirely, or it will introduce a heavy electrical hiss into the recording. This factory-spare cable is custom-wired with the exact pin-outs required to reliably route dual-channel mic audio into modern USB-C mobile devices, laptops, and action cameras.

Core Audio & Engineering Features

• Lossless Balanced Audio Routing: Features a 3.5mm TRS (Tip-Ring-Sleeve) male connector on one end and a USB Type-C male connector on the other. It cleanly carries dual-channel (Stereo/Mono split) audio signals without losing signal strength or degrading high-frequency response.

• Integrated Analog-to-Digital Interfacing: Equipped with high-tolerance internal connection pins designed to interface natively with the host device's digital audio bus. This ensures your smartphone or computer instantly identifies the wireless system as a dedicated external USB audio input, completely bypassing the device's lower-quality built-in microphone.

• Advanced RFI/EMI Shielding: Wrapped in dense internal copper shielding to reject Radio Frequency Interference (RFI) and Electromagnetic Interference (EMI). This is critical when recording close to smartphones, wireless routers, and heavy stage lighting grids that naturally spit out wireless noise.

• Right-Angle low-profile Ergonomics: Designed with an optimized cable layout that prevents the cord from sticking straight out from the side of your camera rig or smartphone cage. This keeps your mobile video rig compact and balanced, while reducing physical strain on the device's fragile USB-C port during fast movements.

System Interoperability

This patch cable is optimized across Hollyland’s audio infrastructure:

• Wireless Microphone Systems: Plugs directly into the analog output port of receivers like the Lark M2, Lark Max, Lark M1, and legacy Lark 150.

• Host Recording Ecosystems: Adapts those microphone receivers directly to Apple iPhone 15/16/Pro series (and later), Android smartphones, iPad Pro/Air models, Mac/PC laptops, and action cameras featuring USB-C audio input protocols (like the DJI Osmo Action or GoPro series equipped with a media mod).

Technical Specifications Matrix

On-Set Mobile Audio Protocol Tip: When connecting your wireless receiver to a smartphone using this cable, always insert the USB-C end into the phone first, wait two seconds for the phone's operating system to register the external sound card chip, and then connect the 3.5mm end into your microphone receiver. This clean digital-handshake sequence prevents the phone's operating system from getting confused, ensuring your native camera app or recording software locks onto the crisp Hollyland audio feed instead of dropping back to the phone's internal microphone.
