Hollyland Spares - 3.5mm TRS to Mobile Phone Patch Cable (for Wireless Microphone Series)

The Hollyland 3.5mm TRS to Mobile Phone Patch Cable (Model: HL-TRS02) is an official OEM replacement and specialized analog audio patch cord engineered for Hollyland’s flagship wireless microphone series.

Standard 3.5mm audio cables are wired as TRS (Tip-Ring-Sleeve) on both ends, which works perfectly for cameras but fails completely when plugged into mobile phones, tablets, or laptops. Mobile devices require a TRRS (Tip-Ring-Ring-Sleeve) hardware architecture to receive an external microphone input. This factory-engineered coiled cable safely bridges that gap, adapting your wireless receiver's output to ensure your mobile device overrides its internal mic and locks onto crisp, external broadcast-quality audio.

Core Audio & Engineering Features

• Hardware-Specific TRS to TRRS Wiring: Configured with a 3-pole 3.5mm TRS male connector on one end (plugs into the Hollyland receiver) and a 4-pole 3.5mm TRRS male connector on the other (plugs into the mobile device). It routes the microphone signal to the precise contact pin that smartphones require to register an external audio source.

• Space-Saving Coiled Ergonomics: Features a resilient coiled layout measuring 4.7 inches (12 cm) resting and expanding up to 15.7 inches (40 cm) when fully stretched. This provides clean cable management, preventing loose loops from dangling into the camera frame or throwing off smartphone gimbal motors.

• Dual Right-Angle Molded Ends: Both connector ends are finished with a ruggedized, 90-degree right-angle profile. This drastically reduces the physical footprint sticking out from the side of a smartphone cage or receiver, minimizing mechanical leverage that can easily bend or break a device’s delicate headphone socket.

• Multi-Layer Anti-Interference Shielding: Built with a dense internal shield wrap to isolate the analog audio signal from Electromagnetic Interference (EMI) and Radio Frequency Interference (RFI). This is critical on mobile shoots, as cellular signals, onboard Wi-Fi chips, and Bluetooth transmitters naturally generate harsh buzzing noises in unshielded cables.

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: Connects natively to older smartphones, tablets, and laptops equipped with a combined 3.5mm headphone/mic jack.

Note on Modern Devices: For modern mobile devices lacking a headphone jack (such as newer iPhones and USB-C iPads/Android devices), this patch cable serves as the primary analog link that connects directly into an official Apple or Android USB-C or Lightning to 3.5mm headphone adapter.

Technical Specifications Matrix

On-Set Mobile Identification Tip: When rigging this cable in a rush, you can easily tell the two ends apart by looking closely at the plastic insulation rings on the metal jacks. The TRS end has two black rings (Tip-Ring-Sleeve), while the TRRS mobile phone end has three black rings (Tip-Ring-Ring-Sleeve). Always make sure the 3-ring TRRS end is the one plugged into your phone or phone adapter; swapping them backward will result in completely dead audio or a failure to detect the microphone.
