Type-C to 3.5mm Headphone Adapter Cable with High-Purity Oxygen-Free Copper 10cm

This Type-C to 3.5mm adapter cable provides a straightforward solution for connecting your existing wired headphones or audio equipment to USB-C devices. With the gradual removal of the 3.5mm headphone jack from many smartphones and tablets, having a reliable adapter keeps your favourite earphones or speakers in use. The cable is built with 99% high-purity oxygen-free copper wire, which helps reduce loss in audio signal transmission and supports clearer sound reproduction. At just 10cm long, it keeps connections neat without tangling or adding bulk. Choose between black or white to complement your device colour.

Features and Construction

The adapter is designed for straightforward plug-and-play operation. Its compact build focuses on delivering a stable audio connection with minimal signal degradation.

Material and Build

The inner wire uses 99% high-purity oxygen-free copper, a material known for reducing resistance and preserving signal integrity during audio transmission. The outer cable has a diameter of OD2.5, giving it a slim profile that stays flexible. The connectors are a sturdy Type-C male plug on one end and a 3.5mm female seat on the other, both built to withstand regular insertion and removal.

Size and Practical Fit

With a total length of 10cm, this adapter is short enough to keep the connection close to the device, reducing the chance of snagging or tangling. This length works well for use with phone cases or when the adapter needs to sit flush against the device body. The compact size also makes it easy to carry in a pocket or bag alongside other accessories.

Uses and Placement

This adapter is suited for anyone who needs to connect standard audio equipment to modern USB-C devices. It covers both everyday and professional scenarios without adding complexity.

Event or Professional Use

For live events, presentations, or recording setups, the adapter allows you to connect 3.5mm microphones, in-ear monitors, or speakers to a USB-C laptop or audio interface. The oxygen-free copper wire helps maintain audio fidelity, which can be important for monitoring or playback in professional environments. The 10cm length keeps the adapter unobtrusive on a crowded desk or equipment rack.

Everyday Home Use

At home, use this adapter to connect your wired headphones to a USB-C smartphone, tablet, or laptop for music, podcasts, or video calls. It also works with gaming headsets that use a 3.5mm plug, letting you play on a USB-C device without needing a separate Bluetooth headset. The slim design means it won't protrude awkwardly when the device is in a stand or dock.

Benefits and Buying Value

This adapter offers a practical, low-cost way to maintain compatibility with existing audio gear. Its core benefits centre on signal quality and straightforward usability.

Reuse and Low Maintenance

Because the cable is passive and has no internal battery or electronics, it requires no charging or software updates. The robust connectors and copper wire should provide a long service life with normal care. Simply plug in and use it as needed, then store it away without special handling.

Why Choose This Product

The main differentiator is the use of 99% high-purity oxygen-free copper wire, which is a material chosen for its ability to minimise signal loss compared to standard copper alloys. Combined with the practical 10cm length and choice of black or white, this adapter covers the essential need of connecting a 3.5mm audio device to a USB-C port without unnecessary frills. It is a straightforward, no-compromise solution for maintaining audio compatibility.
