Features

3.5 mm Audio Adapter Cable Connects to Your Laptop’s USB-C or Thunderbolt 3 Port
Most current USB-C devices, such as Windows laptops, Chromebooks and MacBook Pros, rely on Bluetooth technology for audio and do not come with a 3.5 mm stereo audio jack. The U437-MM1-03 lets you connect a microphone, earbuds, headphones or speakers directly to your laptop or tablet’s USB-C port. You can also use this adapter cable to bypass a defective sound card or audio jack on an older device. It’s ideal for streaming audio, playing music or listening to your favorite podcasts.

Supports High-Fidelity Stereo Audio Formats
This stereo DAC (Digital-to-Analog Converter) supports 94 dB SNR for audio output and 44.1/48/88.2/96/192 KHz sample rate (16/24-bit). The 3.5 mm audio plug supports max 192 KHz/16-bit and 96 kHz/24-bit sample rates that are ideal for listening to music or streaming.

Ready to Use Right Out of the Package
The three-foot (0.9-meter) audio adapter is plug-and-play, so it requires no software or external power. The cable fits easily into a pocket, purse, backpack, briefcase or laptop bag for connecting on the go. It is compatible with Android, Windows and macOS operating systems, including iPads with a USB-C port.
