Status, October 2026: current. Beyerdynamic still lists the DT 770 PRO in 32, 80 and 250 ohm versions, alongside the newer DT 770 PRO X.
What it is
The DT 770 PRO is a closed-back, over-ear studio headphone from Beyerdynamic, handcrafted in Germany and sold in three impedance versions on one product page: 32 ohms, which Beyerdynamic labels for mobile devices; 80 ohms, its universal studio pick; and 250 ohms, for professional devices (Beyerdynamic product page). What Hi-Fi? dates the DT 770 to 1985, five years after the DT 880, and Beyerdynamic has revised it since; the newer DT 770 PRO X, which MusicRadar says has eclipsed but not replaced it, sits beside it in the range.
All three versions share a dynamic driver, a 5 to 35,000 Hz response, 96 dB nominal sensitivity, velour ear pads and a spring steel headband (data sheet). They differ in cable and weight: the 32 ohm version has a 1.6 m straight cable and weighs 325 g, the 80 ohm a 3 m straight cable at 345 g, and the 250 ohm a 3 m coiled cable at 380 g. The cable is single-sided and fixed, and ends in a gold-plated 3.5 mm plug with a 6.35 mm adapter. Beyerdynamic quotes about 18 dBA of isolation from ambient noise for the 80 and 250 ohm versions and about 20 dBA for the 32 ohm.
The ear pads and headband pad are replaceable, and the data sheet lists velour, soft PVC and black velour pad sets as spare parts. The box holds the headphones, the adapter and a drawstring bag; Beyerdynamic sells the Hardcase PRO and DT Hardcase separately. Among the headphones with pages here, the Sennheiser HD 25 is the on-ear DJ standard; the DT 770 PRO is the over-ear studio one.
