Beyerdynamic DT 770 PRO closed Dynamic Studio Headphones - 80 Ohm The Beyerdynamic DT770 Headphones 80 Ohm are closed back dynamic headphones that use the same comfortable, sound isolating design as the 250 Ohm studio version, but with a lower resistance for general purpose and mobile applications. Because of the lower resistance, the DT 770 Pro 80 Ohm headphones are louder and work on low power devices such as smart phones, mp3 player, laptops and bus powered interfaces. Therefore, if you are working in a loud environment or using a battery operated device, the Beyerdynamic DT 770Pro 80 Ohm headphones make the perfect choice of headphone.When out and about, you really need to block as much ambient noise out as possible and a lot of headphones do this by clamping the ear-pads as tightly to your ears as possible and using materials that absorb a lot of sound. This produces two unwanted issues; discomfort, after prolonged use; and a loss of audio quality as sound being generated by the driver is absorbed by the cup. The DT 700 Pro series avoids this by using a clever bass reflex system and a large circumaural cup design with velour pads. Of course the real technology is in the transducer itself, which produces a nominal frequency response of 5Hz to 35kHz and a nominal SPL of 96dB - an exceptional performance.
