USB-C to 3.5mm Audio Adapter 60W

This compact USB-C to 3.5mm audio adapter from phoie pairs high-resolution audio playback with pass-through fast charging, letting you listen to music and charge a device at the same time. It is designed for phones and tablets with USB‑C ports and aims to deliver detailed, low-noise sound for commuting, work, or home listening while providing up to 60W PD charging for uninterrupted use.

Key Points

The adapter includes a professional DAC that decodes up to 384 kHz/32‑bit audio, which according to the manufacturer captures more detail than standard CD quality and preserves subtle vocal and instrumental nuances. Its signal-to-noise ratio of 120 dB and distortion down to -85 dB are reported to keep playback clean and free of audible artifacts, helping reduce listening fatigue during long sessions. The plug-and-play design requires no drivers and supports inline microphone and control functions for calls and playback management. It supports simultaneous charging with PD 60W fast charge, which the brand notes can restore roughly 50% battery in about 30 minutes when using a compatible charger.

Benefits

Having a dedicated external DAC means the adapter bypasses your device’s internal audio processing and aims to deliver lossless transmission to wired headphones. That tends to give a clearer soundstage and more faithful bass reproduction, which is useful for movie soundtracks and critical listening. Also, because it supports inline mic and controls, you can handle calls and change tracks without unplugging the adapter. The combined charging pass-through keeps battery levels stable during heavy use, so you can game or stream without interruptions.

Usage Recommendations

Plug the dongle into a USB‑C port on compatible devices such as recent iPhone models with USB‑C, Samsung Galaxy S series, Pixel phones, and iPad tablets. For the advertised 60W charging rate use a PD 60W charger and an appropriate USB‑C cable. In practice, audio quality benefits most when paired with higher-quality wired headphones that can reveal the extra resolution. Note that volume control behavior may depend on the connected device and certain headset brands, and some phones may use the phone’s side buttons or voice assistant for volume adjustments.

(Consider that manufacturer figures are provided by the brand and listening differences will vary with headphones and source material. The adapter comes with a stated three-year warranty and customer support contact options according to the manufacturer.)
