2-in-1 USB-C & USB-A Audio Adapter

The IIISOGNO adapter combines a USB-C plug and a USB-A connector in one compact dongle, ending in a 3.5 mm TRRS jack for headphones or headsets. It serves mobile users, laptop owners and desktop builders who need a single accessory for both modern and legacy ports.

Integrated DAC chip for Hi-Fi output

A built-in digital-to-analogue converter handles the audio signal, delivering clear and balanced sound for music, video and voice calls without relying on the host device’s internal circuitry.

Braided cable and alloy housing manage heat

The nylon-braided cord and aluminium shell resist tangling and dissipate warmth during extended listening sessions, while the passive design adds no fan noise or extra power draw beyond the host port.

Questions about this item

How does the built-in DAC chip affect sound quality on a laptop or phone?

The integrated DAC converts digital audio to analogue with clear, balanced output, improving detail for music, video and voice calls over the device's own headphone socket.

Which USB standards do the USB-C and USB-A connectors use for audio?

Both connectors carry digital audio through the same internal DAC; the adapter works with any host that supports USB Audio Class over USB-C or USB-A.

What clearance does the 15 cm braided cable and alloy housing need around the port?

The short 15 cm nylon-braided lead and compact aluminium shell sit flush against the device, so only a few millimetres of side clearance is required.
