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.

Beyerdynamic DT770 Pro FAQ:
What are the differences in headphone impedance for?
The different impedances are used for different situations and brought about by a different coil design. The higher impedance headphones use a thinner wire and have a more lightweight design. The lesser weight allows a better movement resulting in a slightly better quality signal. The lower impedance is brought about by a thicker wire which lets more signal through, hence a lower impedance, but the additional weight means the diaphragm doesn't move so accurately.
Which headphones should I buy; 80 Ohm or 250 Ohm?
A pair of 80Ohm headphones are louder and require less power, which is great for mobile or front of house applications where the deficiency in sound quality would not be noticed. A pair of 250Ohm headphones would be more accurate but quieter – which is no problem in a quiet studio with a powerful headphone preamp which you can find on mixers or mains driven audio interfaces.
Should I buy open or closed back headphones?
Closed headphones are primarily designed to keep sound in, so that musicians can listen to audio through the headphones whilst recording using a very sensitive microphone. Any bleed from the headphone would be recorded, so the less audio that escapes, the better. The design also has the reverse effect of blocking outside sound out, making them ideal for use in public or other noisy spaces. The downside is that in order to minimise bleed they need to effectively seal the cup to your ear which means air can't get in or out and the movement of the diaphragm can feel like it is sucking your ear-drum. The second problem is that the materials used to block help limit the amount of audio getting in or out of the cups, also absorb audio being produced by the headphone, especially low end frequencies, thus losing bass response. Therefore, open back are preferable for mixing and prolonged use, the ambient noise that you can hear clearly makes it feel and sound far more natural. Ideally, if you want to mix and record then you should by both open and closed back.
What is a circumaural design?
Circumaural is a term used to describe an ear cup that completely surrounds the ear so that the whole of your ear, pinna included, is contained within the cup.
