Hollyland Spares - USB-C to 3.5mm Headphone Jack Adapter (for Wireless Microphone Series)

The Hollyland USB-C to 3.5mm Headphone Jack Adapter (Model: HL-USB01) is an official OEM audio accessory designed to add real-time monitoring capabilities to mobile wireless microphone setups.

When recording audio directly into a smartphone or tablet using a compact mobile receiver, missing a headphone jack can make it impossible to verify sound quality on the fly. This premium adapter plugs into the digital pass-through port of your receiver, allowing you to monitor live audio or check playback without disconnecting any hardware.

Core Hardware & Signal Processing Features

• High-Fidelity DAC Chipset: Built with an integrated digital-to-analog converter (DAC) chip. This hardware handles the digital audio signal conversion with ultra-low latency, ensuring your headphones mirror exactly what the microphone capsule is picking up without delayed audio lag or background hiss.

• Plug-and-Play Monitoring Infrastructure: Zero drivers or software apps required. Simply plug the USB-C end into your compatible receiver or host device, connect your 3.5mm headphones, and the host system immediately routes audio to your ears.

• Lossless Playback Check: Eliminates the frustration of having to repeatedly unplug your mobile microphone receiver just to listen back to a recorded video clip through your phone speakers.

• Flexible Tangle-Free Build: Constructed using high-flexibility, reinforced internal wiring shielded by an eco-friendly TPE outer jacket. This prevents cable fatigue and physical damage when jammed inside pocket-sized audio accessory pouches.

System Ecosystem Interoperability

This adapter is engineered to expand the mobile workflows across Hollyland's dual-channel mobile ecosystems, natively complementing:

• Lark M2 Series (Specifically plugs into the side USB-C port of the Lark M2 USB-C Mobile Receiver)

• Lark Max Series (Plugs into the Lark Max RX receiver terminal)

• Lark M1 / Lark 150 Mobile Variants

On-Set Monitoring Audio Tip: If you plug your headphones into this adapter and experience complete silence, check your recording app's internal hardware preferences. Some third-party video apps (like Filmic Pro or specialized live-streaming platforms) require you to manually toggle the audio monitoring output from "Default" to "External Headset/USB Audio" before they will open up the real-time audio pipeline to your headphones.
