FONENG BM21 Audio Cable 3.5mm Jack to USB Type-C, White

The FONENG BM21 audio cable is a specialized adapter designed to bridge the gap between modern devices lacking a dedicated headphone port and traditional audio equipment. Featuring a 3.5mm jack to USB Type-C interface, this cable allows users to connect wired headphones, headsets, or external speakers to smartphones and tablets that utilize a USB-C port for audio output. Its compact design and reliable signal transmission make it a practical solution for maintaining high-quality audio connectivity in a portable format.

Advantages

The primary benefit of the FONENG BM21 is its ability to restore compatibility for users who prefer wired audio solutions on devices that have transitioned away from the 3.5mm jack. The cable is constructed from high-quality TPE material, which provides a balance of flexibility and durability, ensuring it can withstand daily use without premature wear. Its lightweight and short 10cm design makes it exceptionally easy to carry in a pocket or bag, ensuring that you always have a reliable audio connection available when needed.

Suitable for

• Connecting wired headphones with a 3.5mm plug to USB-C smartphones
• Listening to music or podcasts on devices without a dedicated audio jack
• Watching movies or media on tablets using wired headsets
• Conducting phone calls using wired hands-free equipment

This cable may not be suitable for devices that do not support audio output through their USB-C port, as it relies on the host device's internal digital-to-analog conversion capabilities. It is also not intended for use with devices that require specific proprietary audio adapters or those that do not follow standard USB-C audio interface protocols.

Key specifications

• Connector A: 3.5mm female jack
• Connector B: USB Type-C male
• Cable length: 10 cm
• Material: Durable TPE
• Color: White

To use the FONENG BM21, simply insert the USB Type-C connector into the charging or data port of your smartphone or tablet. Once connected, plug your standard 3.5mm headphone cable into the female jack end of the adapter. The device should automatically recognize the connection and route audio output through the adapter to your headphones. No additional software or driver installation is required for standard operation.

What to consider before purchase

• Verify that your smartphone or tablet supports audio output via the USB-C port
• Ensure your headphones utilize a standard 3.5mm TRS or TRRS connector
• Consider the 10cm length, which is optimized for portability rather than long-distance reach

For optimal performance and to prevent damage to the connectors, avoid bending the cable at sharp angles near the plug ends and ensure the ports are free of debris before insertion.
