Always a Juno favourite, the DT770s are a bit of a modern classic at this point. Closed back design for good isolation, making them a great choice for most studio work. Supplier's notes: The DT 770 Pro is a closed dynamic headphone and has been designed for critical music and sound monitoring. The single sided cable makes the handling of the headphone easy. The cushion system allows the DT 770 Pro to be used comfortably for long periods of time. The circumaural design with velour cushions and adjustable headband makes the DT 770 headphones really comfortable, even over prolonged periods. The DT 770 250Ohm version is designed for the studio, delivering a higher impedance and a slightly more accurate response than the 80Ohm versions. The higher impedance also means you can safely use multiple headsets from the same source. The 2 most common complaints when mixing using closed back headphones are that they are uncomfortable and don't produce enough bass, leaving mixes overly compensated (see the FAQ further down for the reasons why). The answer to first problem is to buy open back headphones, but they are no good for recording purposes and may not solve the second issue of bass response. Fortunately, the DT 770 Pro tackle both these problems, delivering an impressive nominal frequency response of 5Hz-35kHz using their innovative bass reflex system with a very large cup and velour cushions that let air through but not sound, thus reducing pressure.
