The HD 280 PRO are closed-back, circumaural headphones designed for professional monitoring applications. Although suitable for a very wide range of applications, the exceptional 32 dB attenuation of external noise makes the HD 280 PRO particularly useful for use in a high-noise environment. Highly accurate, linear frequency response means that you hear sound for what it is, with no colouration or artificial boosting of high or low frequencies. The soft earcups fold and rotate to save space, so you can bring your HD280s everywhere you go, and they're comfortable enough to wear all day.
