Beyerdynamic DT287-PV-80
Headset, Single Ear with Condenser Microphone for Phantom Power, 80-ohm Headset

DT287-PV-80

The lightweight, closed DT 287 headset has been developed for professional broadcasting use.

The headphone features an efficient neodymium magnet system, giving very precise reproduction and excellent intelligibility. Another special feature is the wide frequency response of 10-30,000 Hz. The headsets are available with 80 ohm or 250 ohm systems.

The headset is equipped with a condenser capsule with an extended bass response. The microphone can be optimally positioned with the flexible gooseneck. The optimum distance to the mouth is around 5 to 10 cm. The frequency response for this distance corresponds to recommendations of the IRT (Institute for Radiotechnology in Munich). The soft circumaural ear pads and the fully adjustable padded headband offer an outstanding comfort.

The cardioid polar pattern ensures high-gain-before feedback and noise cancellation. The wide frequency resopnse ensures clear and precise speech reproduction and intelligibility.

All parts such as earpads, headband and gooseneck microphone are easy to replace.
