The device features 11mm dual-magnet titanium-composite drivers, achieving Hi-Res Wireless certification and LDAC support for high-bitrate audio. To refine the sound profile, UGREEN collaborated with four-time Grammy winner Terri Lyne Carrington, who helped balance the audio output to ensure depth and spatial range while maintaining the benefits of an open-ear design. Directional acoustics are utilized to minimize sound leakage, allowing for private listening in shared workspaces.

Each earbud weighs approximately 6g and utilizes a 0.5mm memory-titanium core within a C-bridge structure, intended to provide a secure fit across various ear shapes. Beyond audio, the hardware integrates with AI models including GPT and Gemini to facilitate real-time translation across more than 130 languages, alongside live transcription and automated meeting summaries. The battery life reaches 10 hours on a single charge, extending to 46 hours with the included case, and supports dual-device connectivity for seamless switching between laptops and smartphones.
