These new Sennheiser HD 280 headphones combine three usually disparate features: exceptional isolation, loud playback and fold-up design. Designed for broadcast and ENG (that's Electronic News Gathering) applications, studio monitoring or DJ applications, the HD 280's closed dynamic drivers produce linear sound up to 113dB SPL with 1 mW of input power.

The phones have only a 64 ohm input impedance making them easier to drive for a given loudness. Up to 32dB of external noise is reduce in a comfortable way with form-fitting, ergonomically designed circumaural earpieces. The headphones fold up flat when not used making them a good choice if you travel often. The single-sided coiled cable with 3.5mm jack and lockable 1/4-inch adapter is extra extendible (one to three meters) for maximum flexibility. With all parts easy to replace, sound quality is good with a frequency range of 8Hz to 25kHz.
