Out of the box, the Custom One Pro gives you detail across the entire range with slightly recessed mids, fully present treble, and a low end that’ll impress even the most dedicated bassheads. As the cans come with 16 Ohm impedance, they can be driven straight from your mobile device, letting you skip a step in the equipment chain. Built with a rugged spring steel headband and comfortable earpads and headband, you can further customize your Beyerdynamic Custom One Pro Headphones by swapping out the standard, modular cable.
