Perfect when jogging, exercising or roaming around the house while listening to a Bluetooth streaming devise. The DJH-2000BT has the same great features like memory foam leather covered ear pads and a 40mm driver with a frequency response from 20hz to 20 khz. If the internal rechargeable Li-ion battery loses power have no fear as these headphones are included with a detachable 3.5mm connecting cable with gold plated connectors so you are always ready to rock.
