UGREEN 2-in-1 USB-C to 3.5mm Headphone & Charging Adapter - CM231

Listen and Charge at the Same Time — No Compromises

The UGREEN CM231 solves the classic single-port dilemma on modern phones and tablets: it splits one USB-C port into a 3.5mm headphone jack and a USB-C charging pass-through, so you can keep your wired headphones in while your device tops up. A built-in DAC chip decodes audio digitally rather than relying on the phone's own output, delivering high-resolution sound up to 24-bit/96kHz with noticeably lower noise.

On the charging side, the adapter supports PD3.0 and QC3.0 fast-charging protocols for up to 60W, so your device recharges quickly even while you're using it. It's fully plug-and-play — no drivers, no app, no pairing — and works with both CTIA and OMTP headset standards, so most wired earphones and headsets are compatible out of the box.

Built with an aluminum housing, TPE-jacketed cable, and multiple layers of internal shielding, the CM231 is designed to resist signal interference and daily wear. At just 15cm long, it stays compact and tangle-free in a bag or pocket, making it an easy everyday carry for anyone who still prefers wired audio.

• Simultaneous Audio + Charging: Listen through the 3.5mm jack while charging via USB-C — no more choosing one or the other.
