The Ugreen 30757 (CM477) is a high‑quality USB to 3.5 mm audio adapter, offering a compact 25 cm cable with an elegant aluminum alloy shell and braided nylon jacket for enhanced durability and noise resistance.
Inside, a smart DAC chip supports sampling rates up to 24‑bit / 96 kHz, and the signal‑to‑noise ratio (SNR) exceeds 95 dB. It supports both headphone audio and microphone (TRRS / 4‑pole) functionality, making it suitable for headsets with mic, VOIP calls, gaming, and general audio output.
This adapter is plug‑and‑play with no additional drivers needed for most major operating systems (Windows, macOS, Linux). Its compact size and premium materials make it ideal as a portable external sound card or as a replacement for a failing built‑in audio jack.
