Frequently Asked Questions
The DT 1770 Pro uses beyerdynamic's Tesla 2.0 dynamic drivers, engineered to provide high resolution, wide spatial imaging and strong output suitable for mixing, mastering and professional monitoring.
Is this answer helpful?
Yes. Ear pads and the headband pad are replaceable. Clean them with a damp cloth or remove and wash with mild soapy water, then dry completely before reattaching. Never use solvent-based cleaners.

Key specs: frequency response 5–40,000 Hz, nominal impedance 250 Ω, nominal SPL 102 dB, max SPL 125 dB, THD < 0.05% (1 mW / 500 Hz), nominal power handling 200 mW, weight 388 g (without cable).
Is this answer helpful?
Yes. Their closed design, high efficiency and high maximum SPL make them well suited for loud environments such as live monitoring and PA reference listening, offering strong isolation and headroom.
Is this answer helpful?
With a nominal impedance of 250 Ω, many portable sources may not provide optimal volume or dynamics. A dedicated headphone amplifier or a professional audio interface is recommended for best performance.
Is this answer helpful?
Press the small release button on the mini-XLR connector while simultaneously pulling the cable connector from the ear cup. When connecting, ensure the connector locks into place in the ear-cup housing and start with volume set to minimum.

Product Description
beyerdynamic DT 1770 Pro — Premium Studio Headphones
The beyerdynamic DT 1770 Pro is a closed-back, professional studio headphone built around Tesla 2.0 drivers to deliver high resolution, wide soundstage and strong output levels. Designed for mixing, mastering and critical monitoring, the DT 1770 Pro balances clinical detail with musicality, making it suitable for sound engineers, producers and musicians working in loud environments or around PA systems.
Comfort and durability are central to the design: replaceable ear pads (velour and leatherette options) and a swappable headband pad provide long-term wearability and hygiene. The detachable, single-sided lockable cable (3 m straight and 5 m coiled included) connects with a rugged 3-pin mini-XLR and ships with a gold-plated 3.5 mm jack and 1/4" adapter. A hard case is supplied for secure transport and storage.
Technical highlights include a wide frequency response (5–40,000 Hz), nominal impedance of 250 Ω, nominal SPL of 102 dB and a maximum SPL of 125 dB. Low distortion (< 0.05% at 1 mW / 500 Hz) and 200 mW nominal power handling ensure clean performance at high levels. Ambient noise attenuation is strong (approx. 18 dBA with velour, 21 dBA with leatherette), making these headphones effective in noisy monitoring situations.
Maintenance is straightforward: wipe pads with a damp cloth or remove and clean with mild soapy water when needed; avoid solvents and ensure components are fully dry before reassembly. User-replaceable components extend product life, while more involved repairs should be handled by authorized beyerdynamic service to maintain warranty.
For safety, adhere to recommended exposure limits for sound levels (e.g., 85 dB SPL for up to 8 hours, 100 dB SPL for up to 15 minutes) and always start with volume low when connecting. The closed, high-efficiency design provides excellent isolation and headroom for professional use.
Notes
- Includes both straight (3 m) and coiled (5 m stretched) detachable cables and a hard case.
- Replaceable pads and headband components ensure long-term serviceability.
- Ideal for studio mixing, mastering, live monitoring and loud-stage environments.
