Introducing Westone W40 v2, the 2019 updated W40 earphones with fresh sound tuning and now with high-definition audio cable and wireless Bluetooth connectivity. Four custom-made balanced armature drivers elevate your listening experience to higher realms with clarity and realism that four dedicated drivers produce. The W40 v2 will take your listening experience to an entirely new level with unique, warm sound and enhanced balance.

Westone have configured the four balanced armature drivers together with the advanced 3-way crossover network. This creates a significantly higher impact than traditional dynamic drivers, making for enhanced sonic detail and a frequency range that extends well beyond typical in-ear monitors.

With the full-resolution Bluetooth Cable with aptX technology, the W40 v2 delivers extraordinary detail, clarity and a highly dynamic soundstage. Exclusive MMCX connectors allow the Bluetooth Cable to be used with any custom-fit or universal-fit earpiece. Westone have also included it's High-Definition Silver MMCX Cable with low resistance silver-plated copper wire to improve conductivity and provide a more clear and detailed sound.

Breathtaking clarity and realism.
