This headset boasts a large-capacity battery, enabling approximately 23 hours of talk time. It supports HD Voice for clear calls. Ear hooks are included. Bluetooth compatible. The main unit is almost unused, but one of the ear hooks has slightly discolored because it was taken out of the box. The other one is still white as it was kept in a bag inside the box. As you can see in the photos, it was purchased at K's Denki.
