3.5mm Female-Female Audio Coupler

This 3.5mm female-to-female audio coupler is a practical and cost-effective audio adapter designed to extend the length of 3.5mm AUX audio cables or bridge two devices with 3.5mm male audio ports. It is widely used in car audio systems, home entertainment, office audio setups, headphone extension and portable audio scenarios.

Built with high-purity pure copper conductors and gold-plated contact pins, it minimizes signal loss and contact resistance, delivering clear stereo sound quality with reduced background noise. The gold-plated contacts also provide excellent oxidation resistance, ensuring stable and reliable connection even after long-term frequent plug-in use.

Its compact and lightweight design makes it easy to carry and install, truly plug-and-play with no drivers required. The durable hard housing protects internal components from daily wear and tear, suitable for both fixed installation and mobile use. It is fully compatible with all standard 3.5mm TRS audio devices, including headphones, portable speakers, car stereos, smartphones, tablets, laptops, MP3 players, soundbars and standard 3.5mm male AUX cables.

We support custom logo printing, housing color and private-label packaging for bulk OEM & ODM orders, ideal for audio accessory brands and electronic distributors.
