JSAUX 2-Pack USB-C to 3.5mm Headphone Jack Adapter (Blue) – USB-C to Aux Dongle for iPhone, Galaxy, Pixel

Meet the JSAUX 2-pack USB-C to 3.5mm headphone jack adapter, a compact, travel-friendly dongle designed to unlock analog audio from USB-C devices. This dual-pack option means you can keep a spare or share with a friend, all without compromising on portability. The adapter plugs into a USB-C source and delivers a 3.5mm female jack for headphones, headsets, or speakers, letting you enjoy music, videos, or calls with familiar comfort and hardware you already own.

Smart DAC for crisp, faithful sound

Powered by a Smart DAC chip, the unit offers low power draw and stable decoding performance, supporting up to 16Bit/48kHz audio. The DAC converts digital audio to analog while striving to preserve your headphones’ original character, with a 3.5mm port compatible with CTIA-standard headsets. This setup aims to deliver clear highs, balanced mids, and controlled bass without extra software or drivers.

Broad device compatibility

The adapter is designed to fit a wide array of USB-C devices, including newer iPhone models, Samsung Galaxy flagships, iPad Pro, Pixel phones, and more. If you rely on a USB-C port for audio when your device lacks a traditional 3.5mm jack, this accessory can help you keep using your existing headphones or speakers without compromise.

Durable, reliable construction

Engineering focuses on longevity: a reinforced strain-relief design reduces stress during daily use, while shielded enamel wiring helps maintain stable signal transmission. Metal-coated connectors improve contact reliability, contributing to a more consistent listening experience even with frequent plugging and unplugging.

Real-world use cases

• Listening to music or videos on the go from a USB-C phone or tablet using your preferred wired headphones.
• Connecting a portable speaker or headset to a USB-C laptop or handheld device for quick playback.
• Sharing audio from a single USB-C device with a friend or colleague using the same pair of headphones.

Notes and limitations

• Microphone functionality and volume adjustment may not be supported on all headphone models (e.g., some Apple EarPods with 3.5mm plug).
• Not compatible with OMTP, TS, or TRS microphone-only devices.
• Certain iPad Pro models and some Galaxy devices may exhibit limited call control features depending on headset compatibility.

Overall, the JSAUX USB-C to 3.5mm adapter offers a practical solution for users who want reliable 3.5mm audio from USB-C devices. It is designed to be a flexible, durable companion for everyday listening, travel, and desk setups, without making promises about universal compatibility or feature parity across every headset.
