Audio adapter SWISSTEN USB-C to 3.5 mm cable 1.5 m (model 73501303)

SWISSTEN USB-C to 3.5 mm cable 1.5 m (model 73501303) is an audio adapter cable that converts a USB‑C port into a standard 3.5 mm audio jack. The textile-sheathed cable provides a flexible 1.5 m connection designed to link wired headphones, portable speakers or AUX inputs to smartphones, tablets or laptops that lack a dedicated headphone jack. The adapter supports listening to music, making voice calls and connecting external audio equipment where a 3.5 mm connection is required.

Advantages

The SWISSTEN adapter features a durable textile braid that reduces tangling and improves wear resistance while maintaining flexibility. Its universal 3.5 mm jack fits most wired earphones and auxiliary inputs without the need for additional converters. With a 1.5 m cable length, the adapter gives added reach for in-car setups, desk use or connecting to portable speakers. The compact USB-C plug is designed for easy insertion and storage, and the simple passive design ensures compatibility with devices that output analog audio via USB-C.

How to use

Ensure the connected device is unlocked and, if necessary, set the audio output to the connected accessory in the device's settings. For voice calls, use a headset with an inline microphone if the wired headset supports it. After use, disconnect and store the cable to avoid bending near the connectors.

Use the cable with devices that support analog audio output via USB-C. Avoid excessive pulling or twisting of the cable near the connectors. Keep the textile braid clean and dry; if necessary, gently wipe with a soft cloth. For optimal audio performance, use quality headphones and ensure the source device's volume and audio settings are adjusted appropriately.
