HD 280 PRO
Professional Monitoring Headphone

The HD 280 Pro is Sennheiser‘s most significant closed, around-the-ear headphones to be introduced in years. Designed to exceed the demands of the professional environment, the HD 280 Pro boasts extremely robust construction combined with the sound quality, modular design, and aggressive noise isolation that is necessary for the field. The unique collapsible design, combined with swiveling ear cups, offers maximum flexibility in any application.

An accurate representation of audio is key when mixing or mastering your work. Eloquent lows, a distinct midrange, and clear-cut highs are what define the HD 280 PRO’s, making them the perfect companion for recording and mixing sessions. And thanks to their comfort, all those hours spent in front of a screen won’t tire your ears nearly as much as it will your eyes. Found in home and professional recording studios around the world, the HD 280 PRO has become an industry standard for more reasons than one.
Your search for studio headphones begins and ends with HD 280 PRO. Released in 2003, these headphones have stood the test of time. In a day and age where technology renders itself useless in just a few years, Sennheiser is still selling hundreds of thousands of these headphones every year.
