2-in-1 audio adapter Joyroom SY-C02 — Type-C to 3.5mm + Type-C, black

Joyroom SY-C02 is a 2-in-1 audio adapter that converts a device Type-C port to a 3.5 mm headphone jack while also providing a passthrough Type-C port. Designed for smartphones, tablets and laptops with USB-C ports but without a dedicated audio jack, it enables wired headphones and simultaneous charging or data passthrough. The compact black adapter is plug-and-play and intended for calls, music and media playback with preserved audio quality.

Advantages

The adapter features an intelligent DAC chip for lossless audio conversion and clear sound reproduction. It supports PD fast charging up to 60W through the passthrough Type-C port, allowing you to charge a connected device while using wired headphones. The connector uses corrosion-resistant materials and the cable is nylon-braided for improved durability and resistance to bending, abrasion and mechanical wear. The SY-C02 is widely compatible with many USB-C devices.
