It features NTT's proprietary 'PSZ (Personalized Sound Zone)' technology, which aims to reduce sound leakage while keeping the ears open [S1].

Weighing approximately 185g, the device is designed for long-term comfort without the pressure or heat buildup associated with closed-back headphones [S1]. It supports multipoint connection, LE Audio/Auracast, and 360 Reality Audio, with parametric EQ adjustments available via the 'nwm Connect' app [S1].
