JPWEB USB-C to 3.5 mm Headphone & Charger Adapter

USB-C audio and charging adapter

This USB-C adapter adds a 3.5 mm headphone jack and a charging port to devices that lack a built-in socket. It suits owners of recent Pixel, Galaxy, iPad Pro and MacBook models who want wired audio while the battery replenishes. The compact dongle draws power from the host port so no separate supply is needed. Setup is plug and play once the phone’s OTG and developer options are enabled.

DAC performance during extended playback

An integrated DAC chipset handles the digital-to-analogue conversion for music and calls. The chip maintains consistent output during long listening sessions without the distortion that can appear in simpler passive dongles. Because the adapter pulls its operating current from the USB-C bus, sustained use does not introduce extra heat into the headphone cable. Audio quality remains stable as long as the host device can deliver the required bus power.

USB-C interface constraints

The female USB-C port on the adapter carries only power delivery and analogue audio signals; it does not pass USB data. This means the dongle cannot be used for file transfers, tethering or connecting storage peripherals. Compatibility is limited to hosts that implement audio accessory mode over USB-C and support the required OTG toggle. Devices lacking that mode will route sound to their internal speakers instead.
