The HD 280 Pro is a closed-back, circumaural monitor headphone with a collapsible, swivelling-earcup design. It offers extended low-end reproduction with a frequency response of 8 Hz to 25 kHz and up to 32 dB of ambient noise rejection. Neodymium magnets support an extended dynamic range and high output, with thick leatherette earcups and an adjustable padded headband. The single-sided, coiled 3 m (10') cable terminates in a 3.5mm mini-jack with a 1/4" adapter.
