DualBoost charging powers the strap and headset simultaneously, delivering 25 W to the headset. The ergonomic rear support helps balance the weight, while the hinge adjusts from 0° to 52° for an easier fit.
The strap features UL-, EN- and FCC-certified batteries, and its materials have been tested in TÜV laboratories. With a 45 W adapter (not included), charging the strap and headset takes approximately 2.5 hours.
