Beyerdynamic DT 770 PRO 80 Ohm Closed-Back Studio Headphones

Beyerdynamic DT 770 PRO 80 Ohm Closed-Back Studio Headphones

The beyerdynamic DT 770 PRO in its 80 ohm version is the closed-back studio headphone that recording engineers have standardised on for decades: a tracking and monitoring headphone built in Germany, designed to isolate the listener from the room and the room from the microphone. This 80 ohm variant is the middle of the DT 770 PRO range, voiced with the model’s well-known strong bass presence, and it pairs a 3-metre straight cable with velour ear pads and a rugged steel headband. Everything that wears is replaceable, which is why individual pairs stay in daily service for years.

Key features

• Closed-back, circumaural dynamic headphone for studio monitoring and tracking
• 80 ohm nominal impedance, suited to interfaces, mixers and headphone amplifiers
• Frequency response from 5 Hz to 35,000 Hz
• Nominal sound pressure level of 96 dB, power handling of 100 mW
• Ambient noise attenuation of approximately 18 dBA
• 3 m straight cable with gold-plated 3.5 mm plug and 6.35 mm adapter
• Replaceable velour ear pads and a padded spring-steel headband
• Bass reflex system with diffuse-field equalisation

Why studios track with a closed headphone

When a vocalist or musician performs in front of a live microphone, the backing track in their headphones must not leak back into the recording. The DT 770 PRO’s closed earcups attenuate ambient noise by roughly 18 dBA and, just as importantly, keep playback contained, so click tracks and guide mixes stay out of the take. The same isolation works in reverse for editing, podcasting and listening in a shared room: outside noise is reduced without active electronics, batteries or processing. Diffuse-field equalisation shapes the response toward how sound is perceived in a room, and the bass reflex design gives low frequencies a weight that makes checking kick drum and bass parts practical on headphones alone.

The 80 ohm version, specifically

The DT 770 PRO is made in 32, 80 and 250 ohm versions that share a design but not a job. The 80 ohm model sits in the middle: it is voiced with fuller low end than the 250 ohm version, which makes it a popular choice for recording, electronic music production and general listening, and it is efficient enough to reach working levels from audio interfaces, mixing desks, electronic drum modules and portable players, while still rewarding a proper headphone output. Its nominal sound pressure level is 96 dB with total harmonic distortion below 0.2 percent, so the character you hear is the headphone’s tuning rather than strain. If your main source is only a phone or a laptop with a weak output, compare the 32 ohm version; for studio hardware, 80 ohms is the intended match.

Comfort and service life

The headphones weigh 270 g without the cable, and the firm headband pressure — about 3.5 N — keeps them stable during performance without the clamp loosening over time. Soft velour ear pads breathe better than leatherette during long sessions and can be unclipped and replaced in minutes, as can the headband padding. The single-sided 3 m straight cable gives freedom to move around an instrument or a desk and stays out of the way of guitar bodies and keyboards. A screw-on style 6.35 mm adapter converts the gold-plated 3.5 mm plug for console and interface headphone sockets, and a drawstring bag is included for transport.

For recording, monitoring and focused listening where isolation matters, the DT 770 PRO 80 ohm remains the reference point in its class: honest, durable and repairable rather than disposable.
