MORELECS Aux to USB C 10 ft Braided Cable, USB-C to 3.5mm AUX Audio

Connect a USB-C phone to a car stereo’s AUX input and play music through the vehicle speakers with the MORELECS Aux to USB C cable. Its 10-foot length offers practical reach from a dashboard or center-console jack to a phone mount or rear seat, while the braided jacket helps keep the cord manageable for everyday use.

Use it with compatible USB-C phones, tablets, headphones, speakers, or a home stereo with a 3.5mm input. It carries audio from the USB-C device to the 3.5mm audio jack, it does not charge the device or send sound in the reverse direction.

Benefits

The extended cable length makes it easier to position a phone where it is convenient while connecting to an AUX port elsewhere in the car. That can be useful in a truck, with rear-seat passengers, or when the dashboard jack and phone mount are not close together. A round 3.5mm AUX or Line In port is required: a car’s USB port, Bluetooth-only stereo, or a system without an auxiliary input will not provide the connection this cable needs.

The braided exterior, aluminum-alloy connectors, and reinforced cable-to-plug transition are designed for regular handling and plugging in. The cable also uses aluminum foil and oxygen-free copper spiral shielding. Its built-in DAC converts digital audio from the USB-C device to an analog signal for the connected stereo or headphones, it is not an amplifier, so playback level is controlled by the phone and audio system.

The essentials

• Type: USB-C to 3.5mm AUX audio cable
• Length: 10 feet
• Direction: USB-C device to 3.5mm audio input
• Construction: Braided jacket, aluminum-alloy connectors, reinforced joints
• Audio: 3-pole TRS, playback output only
• Compatible devices: USB-C iPhone 15, 16, and 17 series, Samsung Galaxy S21 through S25 series, Google Pixel, iPad Pro, iPad Air, MacBook, and other compatible USB-C devices

For car use, connect the USB-C end to a compatible phone and the 3.5mm end to the stereo’s AUX jack. Some devices may require USB audio to be enabled in Settings. Calls can play through connected car speakers, but the cable does not carry microphone input: the phone’s built-in microphone picks up the caller’s voice. It also does not support recording or voice chat through an external mic.

Customer feedback often highlights music playback, useful reach, and compatibility with older vehicles. Sound quality and durability receive mixed comments, so individual experiences vary, the cable’s documented construction includes a braided jacket and reinforced joints.

Everyday use

This cable suits a simple wired setup when you want to play music from a USB-C phone through a car stereo, headphones, or speaker with a 3.5mm input. Its length gives more flexibility in where the device sits than a short patch cable, while the direct connection avoids needing a wireless audio link. For listening, connect both ends and adjust playback on the phone and stereo. Keep the 3.5mm end connected to an audio input, since the cable is designed to send sound out from the USB-C device, not to receive audio into it.

Should you buy it?

It’s a great fit if you want a long wired connection between a compatible USB-C device and a 3.5mm AUX stereo or audio device. The 10-foot reach, braided build, and clear one-way audio purpose make it a practical choice for car listening and other setups where the phone and audio input are spaced apart.
