Axagon ADA-HC USB-C to 3.5mm jack - Hi-Res DAC audio adapter, 384kHz/32bit, stereo

The AXAGON ADA-HC Hi-Res DAC AUDIO ADAPTER is the ideal accessory for your phone, tablet, laptop or desktop computer with a USB-C connector, providing you with the missing 3.5 mm audio jack. The adapter contains a high-quality DAC converter that offers up to 384 kHz / 32-bit sampling during playback, which ensures excellent sound quality. This adapter is the optimal choice for mobile phones and tablets that are no longer equipped with a headphone jack and only have a USB-C port. Such devices include products from Samsung, Apple (iPhone 15 and later / iPad), Xiaomi, Honor and Huawei.

This audio adapter is optimal for lossless formats like FLAC, WMA, WAV, APE, AAC or ALAC in Apple Music, etc. Listening to music in the highest possible quality is available through premium accounts of platforms such as Spotify, Apple Music, YouTube Music and Amazon Music Unlimited. In addition, you can use this audio adapter for undisturbed viewing of other popular streaming services such as Netflix, Disney+, HBO Max, Amazon Prime or Apple TV+.

Thanks to the DAC converter, with the ADA-HC you can enjoy music in higher quality than using the standard headphone output of your laptop. It will also serve well as a replacement for the non-functioning original sound card in the laptop, thus replacing the headphone output or microphone input. An advantage is also the ability to connect a microphone or headset for communication services WhatsApp, Messenger, FaceTime, Skype, Zoom, MS Teams, Google Meet, Discord, and the like. You can also use it to connect your mobile device to the AUX output in your car.

A stereo 4-pole TRRS connector with automatic CTIA or OMTP standard detection is used to connect headphones. The strength of the 10 cm long cable is ensured by high-quality nylon braiding.

On Windows, macOS, iPadOS, iOS, Android or other supported systems the adapter is usually recognized automatically (Plug and Play). Adjust volume, balance and advanced audio options in the host operating system settings; Windows offers additional options such as virtual surround and sampling rate selection. For recording or voice calls, connect a compatible microphone or headset and select the adapter as the audio input device in the communication app or system settings.

Recommendations

Use quality headphones within the supported impedance range (16–200 ohm) for best results. When using high-resolution playback, ensure your streaming service and account support lossless or high-resolution formats and set the correct sampling rate and bit depth in system audio settings if available.
