BY-K4 3.5 mm TRS to USB-C Cable

The BOYA BY‑K4 is a compact audio adapter cable that lets you connect microphones, audio equipment, or headphones with a 3.5 mm TRS (female) jack to devices that only have a USB‑C port — like most modern Android smartphones, tablets, and some laptops. It’s plug‑and‑play, requiring no drivers, and is ideal for connecting external mics to record audio directly on your USB‑C device. The adapter supports clear digital audio transmission (up to 48 kHz) with a durable build and flexible design for everyday use.
