Acefast J12 USB-C to 3.5mm mini jack adapter - black

The Acefast J12 is a compact USB-C to 3.5mm audio adapter with digital-to-analog signal conversion that delivers lag-free, high-fidelity sound. The connector housings are made of aluminum alloy with TPE, and the gold-plated 3.5mm jack protects the contacts from oxidation and ensures a durable connection. Nylon braiding reinforces the cable, and at just 6g and 15cm long, the adapter is easy to carry with you wherever you go. It supports both audio playback and voice calls with a microphone, and plug-and-play operation eliminates the need for drivers.

The Acefast J12 features zero-latency digital-to-analog conversion, preserving full sound quality. The wired connection provides more stable audio transmission than wireless solutions—perfect for music, streaming, and conference calls.

The adapter supports microphone functionality, allowing you to use headphones with a microphone for phone and voice calls without the need for additional accessories. This is a significant advantage when connecting headsets to devices without a 3.5mm jack.

Aluminum alloy connector housings with a TPE coating are scratch-resistant and resistant to everyday wear and tear, while the gold-plated 3.5mm jack prevents contact oxidation. Nylon braiding along the entire length of the cable protects it from bending and tearing.

At a compact 15 cm in length and weighing just 6 g, the Acefast J12 easily fits in a pocket or bag alongside your phone. Plug & play means you simply plug it in—no drivers, no configuration, no waiting.

The adapter works with phones, tablets, computers and car audio systems equipped with a USB-C port - wherever there is no 3.5 mm jack and the user wants to use wired headphones or speakers.
