The headphones feature a 7mm micro-dynamic driver unit, designed to maintain a small size while providing rich sound details and density. The diaphragm is made of a beryllium-plated composite, utilizing beryllium's high sound speed of 12,890 meters per second to improve transient response.

The manufacturer used a magnetron sputtering process to keep the beryllium layer thickness under 2µm, balancing high, medium, and low frequencies. The driver is powered by an N52 strong magnetic core, which increases efficiency for the beryllium-plated composite diaphragm.

The device includes an L.S.W. low-standing-wave aluminum alloy acoustic rear chamber to smooth airflow. For connectivity, it uses high-purity OFC oxygen-free copper braided HiFi cables, which reduce weight and and minimize the stethoscope effect.

The Yves+ model is available in black, green, and orange colors with a gear-shaped metal shell. Each earbud weighs 1.3g. The included dual-hardness noise-isolating ear tips can block up to 35% of external noise.
