The UGREEN 30757 USB-A to 3.5mm Audio Adapter works as an external USB sound card, allowing you to connect headphones, earphones, headsets and speakers with a standard 3.5mm jack to a USB-A port. It is especially useful for computers with a damaged, missing or inconvenient built-in audio jack.
With its built-in KT0210 DAC, the adapter supports up to 24-bit/96kHz audio output and also supports microphone input through compatible TRRS headsets. The combination of plug-and-play operation, in-line control support and durable aluminum-alloy construction makes it suitable for music, gaming, online meetings and everyday PC use.
