## Long description

The BOYA BY-K4 3.5mm to USB Type-C audio cable is a compact adapter cable that converts a standard 3.5mm female jack to a USB-C male connector. It is designed to provide a direct physical connection between 3.5mm-equipped microphones, headphones or other analog audio equipment and devices with a USB Type-C port. The black cable emphasizes a simple, functional design intended for reliable everyday use.
Advantages
The adapter offers plug-and-play compatibility for devices with USB Type-C ports, removing the need for additional power or software. Its 3.5mm female connector accepts common TRS/TRRS plugs, enabling use with a variety of headphones and external microphones. The compact form factor and single-cable design reduce clutter and make it easy to carry with mobile phones, tablets and laptops. The build focuses on stable electrical contact and a durable exterior to maintain consistent audio signal transfer.
Suitable for
Connecting external microphones with a 3.5mm plug to smartphones, tablets and laptops that have USB-C ports
Using wired headphones or in-ear monitors with devices that lack a 3.5mm jack

How to use
Insert the 3.5mm plug of your microphone or headphones into the 3.5mm female jack of the BOYA BY-K4, then connect the USB Type-C male end to the USB-C port of your phone, tablet or laptop. Most modern devices will recognize the connection automatically; if necessary, select the external microphone or wired headset in the device audio settings. Avoid excessive bending near the connector joints and ensure a snug fit to maintain signal integrity.
Usage recommendations
For best results, use the adapter with devices that officially support analog audio over USB-C or with apps that allow external microphone selection. Inspect connectors regularly for dust or debris and disconnect gently to prolong cable life. This adapter is intended for audio signal transmission and may not provide inline controls or microphone bias features on all device combinations.
