Product Overview
The beyerdynamic DT 770 PRO is a wired, closed-back over-ear headphone designed primarily for professional monitoring, recording, and critical listening. This configuration uses an 80-ohm nominal impedance and is identified by manufacturer article number 474746 and EAN 4010118474743. The headphones use a circumaural design that surrounds the ears and provides passive acoustic isolation without electronic active noise cancellation.
The DT 770 PRO has a documented frequency response of 5 Hz to 35,000 Hz and a nominal sound pressure level of 96 dB. A straight cable terminates in a 3.5 mm stereo plug, and a 6.35 mm adapter is provided for equipment using the larger professional audio connector. Replaceable ear pads and other serviceable components support long-term professional use. This 80-ohm configuration should be distinguished from other DT 770 PRO impedance versions because electrical requirements and product identifiers can differ.

Product Identifier Summary
The model number and MPN identify the specific manufacturer configuration within the DT 770 PRO family. The EAN is a standardized product identifier used by retail, distribution, and inventory systems to identify the packaged 80-ohm configuration.
Common Uses
The DT 770 PRO is commonly used for studio monitoring, recording, audio production, editing, and critical listening. Its closed-back construction helps reduce the amount of external sound reaching the listener and limits sound leakage compared with an open-back design.
Maintenance & Care
Keep the headphones dry and clean the exterior with a soft cloth. Ear pads and the headband should be inspected periodically for wear. Several components, including ear pads and headband parts, are available as replaceable service items.
Safety Information
Extended listening at excessive volume levels can contribute to hearing damage. Users should select an appropriate listening level and verify that connected audio equipment can properly operate an 80-ohm headphone load.
