What this adapter does

The Corn Electronics USB-C to 3.5mm Audio + PD 27W Adapter adds a 3.5mm headphone jack and a USB-C power input to devices that only have a single USB-C port. It supports 32bit 384KHz digital audio and delivers up to 27W of Power Delivery 3.0 pass-through charging while you listen. The 12.5cm cable uses aluminum alloy and TPE materials for a compact, plug-and-play solution.

Audio and charging limits

The adapter handles 32bit 384KHz audio output, but the actual quality depends on the source device's DAC and the headphones connected. Power Delivery pass-through is rated at 27W with a 9V/3A profile, so laptops or tablets that require higher wattage will charge more slowly or not at all. The single USB-C male connector occupies the host port, leaving no spare data lane for other peripherals.

Installation notes

Plug the USB-C male end into the host device, connect headphones to the 3.5mm female jack, and attach a USB-C charger to the PD port to enable play-while-charging. The short 12.5cm cable reduces strain but limits placement options on larger devices. Some phones with strict accessory authentication may not recognise the adapter, and cases with tight port cutouts can prevent the connector from seating fully.

Questions about this item

Should I choose the grey 12.5 cm model or a different length?

The adapter is only offered in grey with a 12.5 cm cable, so there is no alternative length or colour to select.

What does the 32-bit 384 kHz rating mean for daily listening?

It indicates the DAC supports high-resolution audio up to 32-bit depth and 384 kHz sample rate, preserving detail from lossless files.

How does the USB-C PD 27 W port limit charging speed?

The PD 3.0 port delivers up to 27 W at 9 V / 3 A, so connected devices charge at that maximum rate while audio plays.
