What this adapter does

The Cebkit 404 is a USB-C to 3.5mm audio adapter that adds a 3.5mm auxiliary jack and a USB-C Power Delivery 3.0 charging port to phones and tablets lacking a built-in headphone socket. A built-in DAC noise-reduction chip handles digital-to-analogue conversion so wired headphones work while the device charges. Inline controls support call answer and volume adjustment. The purple finish distinguishes it from standard dongles.

Who should buy it and who should not

Buyers with USB-C phones — including recent iPhone 15 or 16 series, Samsung Galaxy S or A series, Google Pixel or Motorola handsets — who want to keep using 3.5mm earbuds without losing charging capability. Users whose devices already provide a 3.5mm port or who rely on wireless headphones gain no benefit. The adapter only serves devices that support audio and PD charging over the same USB-C port; proprietary or audio-only ports will not work.

The spec that decides fit

The single deciding specification is the presence of a USB-C port that carries both analogue audio output and USB Power Delivery 3.0 input simultaneously. If the host device does not support audio accessory mode together with PD 3.0 charging through its USB-C connector, the adapter cannot deliver sound and power at the same time.

Questions about this item

My phone only has a USB-C port — do I need anything besides this adapter to use my 3.5 mm headphones?

No. The Cebkit 404 plugs into the USB-C port and provides a 3.5 mm jack for your headphones while also passing through PD 3.0 charging.

Will this adapter work with an older Galaxy S10 that still has a headphone jack?

Yes. The adapter connects via USB-C, so the S10 can use it for audio and charging even though the phone retains its own 3.5 mm socket.

How can I confirm the built-in DAC is active after I plug the adapter in?

Audio plays through your 3.5 mm headphones, the inline microphone and volume controls respond during calls, and the phone charges at PD 3.0 speed while audio is running.
