Title: Professional headphones with volume
Author: Patric Louis
Translated from the original German article
The DT 1770 PRO makes a rugged and solid impression.
With a weight of 388 gram (without connected cable) it is not one of the lightest headphones, but even though it is not uncomfortable to wear. One important issue: For beyerdynamic headphones you can get spare parts, even after centuries!
The appearance of the DT 1770 PRO is a noble one. All parts are in matt black which reminds me initially of matt black luxury cars competing with the Batmobile on the road for some time. (...) the DT 1770 PRO makes this design look valuable and precious. The adjustable headband, the yokes and cables appear expensive, but are reduced to a minimum emphasising the simple elegance.
Due to extra clear highs the DT 1770 PRO sounds surprisingly open. It is louder than my other headphones and is remarkably deep and with many highs, a beautiful sound! The spatial reproduction and the clean stereo image does not leave you time to think about the advantages or disadvantages of closed headphones. After the first few jumps between my favourite titles I am in a certain madness of collecting audio impressions and can hardly wait to listen to many other titles, as I have the impression that I now hear for the first time how these titles really sound.
For me the frequency response provides a powerful bass, relatively low mids and remarkable highs. It reminds me a little bit of the volume button on stereo systems. The middle nose typical in many other closed headphones which mostly sounds like unpleasant cabinet resonance is not heard. The middle frequency range from 300 Hz to 1 kHz could be 1 to 2 dB louder in my opinion, but everything else that is heard makes me doubt my previous headphones. A rich, not slurred bass and crispy precise highs, as I have rarely heard so far. This is what makes listening fun!
Impulse behaviour: The rim clicks of my reference piece “The Hounds of Winter” by Sting sound as pointedly as they were probably intended by Vinni Colaiuta. A dream! Normally I know such clean sounding transients from pure acoustic live music only or from Manger loudspeakers. The DT 1770 Pro succeeds in this precision due to beyerdynamic’s latest Tesla 2.0 moving coil technology, indeed the whole range of all music titles I listen to.
(...) Regarding stereo image and bass differentiation the DT 1770 Pro meets all desires. I cannot hear any imbalance and would grant this headphone only a very low in-head localization. Compared to the closed AKG K270 I cannot hear an exaggerated wide stereo image. The K270 almost sounds opposite phase compared to the DT 1770, signals that wander in the panorama, are almost indefinably heard with the K270, while the 1770 reproduces almost everything precisely.
The DT 1770 Pro opens sonic worlds, which are unrivalled among closed headphones. Precise and fine sounding, loud and yet free from distortion, comfortable and processed of a high quality, the DT 1770 Pro will soon advance to the preferred headphone in recording studios and live application. It can handle unbelievable high levels and remains without distortion even with loud volumes. Due to the closed design it features an excellent ambient noise attenuation and provides almost a kind of measuring device for the ears due to the audio precision, if there were not the relatively reluctant mids. You can appreciate the sound properties of the beyerdynamic DT 1770 Pro when you listen with it for a while. Its strong bass lets you know when it is too much. The clear and emphasised highs make you feel what happens in the upper frequency range and the under-represented mids might lead to warm mixes. What else could you ask for?
High-impedance and nevertheless loud
Most precise high frequency response and impulse behaviour
Strong bass response
Clear spatial reproduction
No disturbing mid response despite closed design
All parts replaceable
Somewhat weakly remarkable mids
