The Beyerdymanic DT 770 is a closed back dynamic headphone and was designed for critical music and sound monitoring in an open environment.
The Beyerdymanic DT 770's transducers are fitted to adjustable yokes which should be positioned to fully enclose the ear. This will provide the optimum ear/speaker position for accurate sound monitoring. The coiled cord can be extended to a maximum of 3 m and is terminated with a high- quality gold plated mini-jack and a 1/4" stereo jack adapter.
These headphones are designed for optimum listening quality in situations where open headphones would be inappropriate, the lightweight diaphragm, which is around one-fifth the mass of that used in other beyerdynamic designs, gives a high-end transparency that challenges that of electrostatic headphones.
The DT770 features circular, fully sealed acoustic chambers with foam-filled velour ear cushions that fit over, rather than resting upon, the ears. Inside is a ported bass reflex system and the frequency response is quoted as 5Hz to 35kHz. A 3m coiled cord is fitted to the phones and terminates in a gold-plated quarter-inch jack plug -- unscrew the barrel and there's a 3.5mm stereo jack inside. Each phone is supported in an anodised aluminium yoke and these are in turn supported by a well padded, adjustable headband.
Listening on headphones is a different experience to listening on loudspeakers, but the overall tonal balance is surprisingly close to that of a pair of top-flight monitors. You don't get the same physical impression of bass because only your ears are involved, whereas with speakers it's your whole body, and the stereo image always seems to exist inside your head rather than in front of it, but for track laying late at night or for scrutinising a mix for imperfections, the DT770s are hard to fault.
