usb aux extension cable

These listings use USB-C and 3.5mm audio connectors in male-to-male and male-to-female configurations. Some listings also specify TRS or TRRS wiring (TRS for stereo; TRRS for stereo plus microphone support).

Descriptions indicate broad compatibility with most USB-C phones, tablets, and laptops. Many adapters also target car stereos, powered speakers, receivers, soundbars, home theater and Hi‑Fi systems for stereo audio connections.

Some adapters include both a 3.5mm audio port and a USB-C charging passthrough so you can route audio while supplying power. Product descriptions for those models often state 'listen and charge' or 'audio & charging at once.'

Warranty coverage varies by listing: some show a limited lifetime warranty while others list a 1‑year limited warranty. Check the specific product page for exact terms and any support contact details.

Some cables advertise TRRS support, which provides conductors for left/right audio plus a microphone line. Product descriptions also note that microphone functionality typically requires headphones with a built‑in mic and that you should verify the listing to confirm mic support for your device.

One adapter description mentions compatibility with USB Power Delivery or Quick Charge 2.0 chargers and states it can unlock fast charging speeds up to 60W when used with a compatible charger and device.
