The BOYA BY‑K4 USB‑C to 3.5 mm TRS Adapter Cable is a short, lightweight audio adapter designed for connecting devices with a 3.5 mm TRS male plug—such as traditional microphones or audio gear—to devices with a USB‑C port like Android phones, tablets, and some laptops.
This cable provides stable audio transmission and is ideal for recording with external microphones or using audio equipment with modern USB‑C only devices. Its compact 6 cm length makes it portable and easy to carry for mobile recording, interviews, or content creation.
Designed for plug‑and‑play use, the BY‑K4 requires no drivers or software—just connect your 3.5 mm TRS device into the adapter and plug the USB‑C into your smartphone or tablet. Cable durability is enhanced with reinforced strain relief to withstand frequent use.
