The Tunez Nexus CB-80 is a USB Type C to 3.5 mm audio cable with a built in DAC, designed to connect compatible Type C devices with wired earphones, headphones, speakers, and car audio systems with a 3.5 mm AUX input. Its compact 14 cm length and braided construction make it suitable for everyday portable audio setups.
Unlike a standard USB Type-C charging or data cable, the CB-80 is designed specifically for wired audio connectivity, with the DAC handling the conversion required for a 3.5 mm analogue audio connection.

Built-in DAC for Type-C Audio
USB Type-C devices can transmit digital audio, while traditional 3.5 mm audio connections use an analog signal. The CB-80 includes a Digital to Analog Converter (DAC) to convert the digital audio signal into an analog output for compatible 3.5 mm audio equipment.
The DAC is therefore an important part of this cable’s operation. It allows the CB-80 to provide a direct Type C to 3.5 mm connection without requiring a separate DAC adapter.
Device Compatibility
The CB-80 works with USB Type-C devices that support audio output through their Type-C port. This can include compatible smartphones, tablets, laptops and other Type C devices.
A Type C connector by itself does not guarantee audio compatibility. Some devices support Type-C charging and data but do not provide wired audio output through the port. Checking the device manufacturer’s specifications is recommended when compatibility is uncertain.
Connect Type C Devices to 3.5 mm Audio Equipment
The CB-80 is suitable for common wired audio connections, including:
- USB Type C smartphone to 3.5 mm earphones or headphones
- USB Type-C device to a car stereo AUX input
- Laptop or tablet to compatible speakers with a 3.5 mm input
- Compatible Type-C device to other standard 3.5 mm audio equipment
- Wired headsets for supported voice calls
For car audio, the vehicle must have a functioning 3.5 mm AUX input.
Compact Braided Construction
The CB-80 measures 14 cm, making it useful when a short connection is preferred. The compact design helps reduce excess cable around smartphones, laptops, car consoles and other portable audio setups.
Its braided outer construction is designed for regular handling and helps protect the cable from everyday wear.
How to Use the CB-80
Connect the USB Type-C end to a compatible device and plug the 3.5 mm end into your earphones, headphones, speaker or AUX input. Once connected, select the appropriate audio output on the source device if required.
If audio is not detected, first check whether the Type C port supports USB audio output and whether the connected 3.5 mm accessory is functioning correctly.
Important Things to Know Before Buying
The CB-80 is an audio cable, not a general-purpose Type C charging or data cable. It is intended to provide wired audio connectivity between compatible Type-C devices and 3.5 mm equipment.
Compatibility should also be checked before purchase because Type C ports can have different capabilities depending on the device.
