viwomik USB-C to 3.5mm Earphone Jack Adapter – Built-In DAC Audio Converter with Microphone Support for Type-C Smartphones

This generic USB-C to 3.5mm TRRS audio converter is a compact, plug-and-play digital audio adapter exclusively designed for modern smartphones, tablets and laptops that eliminate the traditional 3.5mm headphone jack. Equipped with an independent built-in DAC (Digital-to-Analog Converter) chip, it solves the audio connection dilemma of Type-C devices, supporting stereo music playback, built-in microphone pickup and hands-free calling all in one lightweight unit. This white mini audio dongle delivers stable lossless audio transmission without extra software or driver installation, and works seamlessly with most mainstream USB-C electronics including the iPhone 17 Pro Max as verified by real buyer tests.
Core Functional Features
Integrated DAC Digital Audio Decoding
The embedded dedicated DAC chip converts digital audio signals from USB-C ports into analog stereo sound, effectively filtering out static noise, current hum and electromagnetic interference. It restores full, layered sound details for music, podcasts and video streams, offering smoother audio output compared to cheap passive adapters without decoding chips.
Full TRRS 4-Pin Audio & Microphone Support
Unlike basic TRS-only adapters that only play sound, this converter adopts standard TRRS pin layout to enable two-way audio transmission. It fully supports the inline microphone of your 3.5mm headsets, allowing crystal-clear voice capture for mobile calls, video conferences, online classes, gaming voice chats and voice recording apps. Headset line control functions like play/pause and call answering are also fully compatible.
Multi-Scenario Aux Connection
It acts as a universal aux audio bridge for daily usage:
Connect wired 3.5mm earphones, over-ear headphones and gaming headsets to Type-C phones/tablets
Link mobile devices to car AUX audio systems for in-car music playback
Hook up portable speakers, desktop soundbars and outdoor audio equipment
Ideal accessory for remote meetings, content creation and casual entertainment
