USB-C Audio Adapter with Charging

The DESOFICON CNTX-CA136 is a three-pack of USB-C to 3.5mm adapters that add a headphone jack and a Power Delivery charging port to phones and tablets lacking a built-in audio socket. It is aimed at listeners who want to keep using wired headsets while the device charges.

PD Charging and Audio Limits

Each adapter accepts up to 60 W of Power Delivery input so the host device can fast-charge during playback. The dongle does not transfer data, so it cannot be used for file sync or tethering. Compatibility depends on the host supporting audio accessory mode over USB-C.

24-bit 48 kHz DAC Specification

The built-in digital-to-analogue converter outputs 24-bit audio at a 48 kHz sample rate with noise reduction. That resolution decides whether the adapter meets a buyer's fidelity requirement for wired listening.

Questions about this item

Should I pick the single adapter or the 3-pack for my iPhone 15 and iPad Pro?

The listing is a 3-pack, giving you three identical USB-C to 3.5mm dongles so you can keep one at your desk, one in a bag and one as a spare for iPhone 15, 16 or 17 models and USB-C iPads.

What does the 24-bit / 48 kHz spec mean when I plug in my wired headphones?

It means the adapter’s built-in DAC converts digital audio at 24-bit depth and 48 kHz sample rate, delivering CD-quality stereo sound with low noise to any 3.5 mm headset.

Does the USB-C port on the adapter carry data or only charging and audio?

The USB-C female port supports PD fast charging up to 60 W and audio pass-through only; it does not carry USB data, so you cannot use it for file transfer or accessories that need a data link.
