AT-C/55 USB-C to 3.5mm Cable
One cable to reconnect with great sound

High-resolution and stable transmission USB-C to 3.5mm cable

As more and more devices switch to the USB Type-C interface, how to stably connect mobile phones, tablets, or computers to headphones has become a common user need. Often, when sound performance is less than ideal, it's not necessarily the headphones that are lacking, but rather the connecting cable in between affecting the overall sound quality, details, and stability.

The AT-C/55 launched by SoundWiser is born exactly for this purpose. It is not just a simple signal connection, but a USB-C to 3.5mm cable that ensures both high resolution and stable transmission. Used with headphones equipped with a 3.5mm jack, it allows Type-C devices to connect to the headphones, continuing the familiar listening experience while unleashing the headphones' proper sound performance. In addition, the AT-C/55 can also be extended for use with in-car AUX and other 3.5mm audio equipment, offering greater flexibility in use.

8-strand silver-plated monocrystalline copper cable

8-Strand Silver-Plated Monocrystalline Copper Cable
Restoring Headphone Potential


The AT-C/55 utilizes an 8-strand silver-plated monocrystalline copper cable. Each strand is twisted from 49 silver-plated copper wire cores with a diameter of 0.06mm, which helps improve signal transmission stability while retaining more sound details. For users who value sound performance, this cable configuration reduces loss during transmission, resulting in clearer sound contours and more complete details, further unleashing the headphone's original sound performance.

Dedicated protective case to protect against scratches and dust

Equipped with CX31993 DAC Decoding Chip
Supports High-Resolution Playback


The AT-C/55 has a built-in American Conexant CX31993 DAC decoding chip, supporting 32bit/384kHz high-resolution audio to perfectly present audio source details. Whether it's lossless music, high-resolution audio, or high-quality music from streaming platforms, it reveals clear sound contours and details, delivering a more balanced listening experience.

Directly output mobile phone Type-C audio to in-car 3.5mm

Not Just for Headphones
Equally Suitable for In-Car AUX and Active Speakers


The AT-C/55 features a USB Type-C and 3.5mm dual male connector design. Besides connecting headphones, it can also output a mobile phone's Type-C audio directly to an in-car 3.5mm AUX, making it convenient to play navigation voice, music, and other audio content through the car stereo. It can also connect to active speakers and other equipment, expanding everyday playback needs.
