One of the first in the market with Ambient Aware technology that allows you to keep listening to the music while being aware of your surroundings so that your inspiration flow won’t stop. This does not sacrifice in any way the AKG audio quality using the closed back acoustic configuration coupled with Bluetooth technology. With 33-hour battery life and quick charge top up, the Y500 WIRELESS can switch music/calls seamlessly between 2 devices. These headphones come with a soft-touch headband, aluminum ear buds, zinc-alloy hinge rotators, polished steel metal hinge and memory foam cushions. All of these materials contribute to the durability and comfort of the product.
