Beyerdynamic DT 770 PRO: The Reference Headphones from Heilbronn
· re:union Radio editorial · 2 min read
The Beyerdynamic DT 770 PRO is a closed-back reference headphone for studio monitoring, handcrafted in Germany and repairable.
The Beyerdynamic DT 770 PRO is a closed-back, over-ear headphone that Beyerdynamic specifically developed for critical music and sound control in the studio. The manufacturer from Heilbronn describes it as a reference headphone for control and monitoring purposes, intended for music producers, sound engineers, and broadcasters.
At a glance
- Closed-back, circumaural design (fully encloses the ear)
- Available in three impedance variants: 32, 80, and 250 ohms
- Frequency response from 5 to 35,000 Hz, sound pressure level 96 dB
- Handcrafted in Germany, all components are replaceable
Three Variants for Three Use Cases
What sets the DT 770 PRO apart from many competitors is its staggered impedance. The 32-ohm version is designed for mobile devices, the 80-ohm version is considered a universal studio variant, and the 250-ohm version is aimed at professional equipment with a correspondingly powerful headphone output. So, if you're mixing on a laptop instead of a studio interface, you'll choose a different variant than if you're at the mixing console in the control room.
Closed-Back Design for Controlled Environments
The circumaural, closed-back construction fully encloses the ear and attenuates external noise. This makes the model a typical representative of the closed-back reference class: designed for recording situations where no sound from the headphones should leak into the microphone, or for monitoring in louder environments. The model is designed for continuous use in professional daily life.
Repairability as a Principle
Beyerdynamic promotes the DT 770 PRO with an argument that has become rare in the headphone market: repairability. All components – from the ear pads to the cable – can be replaced instead of replacing the entire device in case of a defect.
