This description matches the USB-C to 3.5mm Hi-Fi Audio Adapter (often referred to as an "Active Dongle" or "DAC Adapter"). It is the essential bridge for modern devices that have removed the headphone jack, allowing them to communicate with legacy analog audio equipment.

USB-C to 3.5mm Hi-Fi Adapter | Universal Audio Bridge

• Integrated Hi-Res DAC Chip: Most premium adapters feature a built-in Digital-to-Analog Converter (DAC). This chip takes the raw digital signal from your phone and converts it into a high-fidelity analog signal (up to 24-bit/96kHz), ensuring your music sounds better than a standard built-in jack ever did.

• Broad Device Compatibility: Unlike "passive" adapters that only work with specific phones, this Active adapter works with almost all USB-C devices, including:

• Apple: iPhone 15/16/17 series, iPad Pro, and MacBooks.

• Android: Samsung Galaxy S21-S26 series, Google Pixel, and OnePlus.

• Laptops: Dell XPS, HP Spectre, and Chromebooks.

• Lossless Audio Transmission: Built with high-quality oxygen-free copper (OFC) wiring to prevent signal interference and static, providing a "noise-free" experience for your Hi-Fi home system or car stereo.

• Full In-Line Control Support: Supports microphone input and wire-control functions (volume +/-, play/pause) for standard CTIA and OMTP headphones.

• Usage Scenarios

• Car Audio (AUX-IN): Connect your phone directly to an older car’s 3.5mm AUX port to stream Spotify or Apple Music without needing a Bluetooth FM transmitter.

• Home Hi-Fi Systems: Bridge the gap between your modern laptop and a vintage amplifier or high-end wired speakers.

• Pro Audio & Gaming: Connect high-impedance studio headphones or gaming headsets that require a steady, uncompressed audio signal.
