The Beyerdynamic DT 1770 PRO are great closed-back critical listening headphones with a good and balanced sound. They are well-built and offer great comfort if you like a tight fit. They are more versatile than similar open-back models like the DT 1990 PRO and DT 990 PRO because they will isolate more noise and leak less. However, they are bulky, and the provided case is quite big, meaning they won’t be very portable. On the upside, they have a detachable cable that the lower-end Beyerdynamic models don’t have.
The Beyerdynamic DT 1770 PRO are very well-built headphones that are basically like the DT 1990 PRO, but with a closed-back design. Their metal frame and dense cups give them a premium and solid feeling, and they should survive a couple of drops. They are quite comfortable and come with two types of ear pads. However, they might be tight on the head for some right out of the box, but this may loosen up with time. They have a bulky design and come with an even bulkier case, so they won’t be easy to travel with, but they will be well-protected.
The Beyerdynamic DT 1770 PRO are basically the closed-back version of the DT 1990 PRO and a more high-end pair of headphones than the DT 770. They have a very similar style with black velvet-like fabric instead of a grey one and also come with leather pads if you prefer that style and comfort. They have big circular ear cups with a thick metal frame which gives it a sturdy look but are low-profile enough to wear outside.
They are very comfortable headphones, but compared to the Focal Elegia, they are a bit tight on the head for some people. They have great padding and come with two options of pads, velvet, and leather, and the cups are big enough to fit most ears. Unfortunately, they might take some time to loosen up, as they are not as comfortable right out of the box like the DT 880.
The Beyerdynamic 1770 PRO are simple wired headphones that do not have any controls on the ear cups or an in-line remote.
These closed-back headphones don’t have much airflow compared to the open-back DT 1990, but they are still decently breathable. They won’t be a great option for physical activities as they might make you sweat more while wearing them and the ear pads you use might have a different result in breathability. We measured the DT 1770 with the velvet pads.
Like most Beyerdynamic headphones, the DT 1770 PRO are not very portable. They have a bulky build that doesn’t collapse into a more portable format. They also don’t have cups that can swivel to lay flat. You will need to use a bag or the provided hard case to bring them on-the-go with you.
Update: 04/10/2019 We've updated the score of the Beyerdynamic DT 1990 PRO and 1770 PRO's cases to better reflect their durability compared to that of the T1 2nd Generation and other similar hard cases.The Beyerdynamic DT 1770 PRO come with a big hard case which is very similar to the DT 1990 PRO’s case. It will protect the headphones from scratches, drops and water exposure. However, the case is quite big and won’t fit everywhere, making it a bit harder to carry it around.
The 1770 PRO are no exception to the well-built lineup of Beyerdynamic. They have a very premium build and feel high-end. These headphones also have detachable and replaceable cable and ear pads, unlike the DT 770 PRO. The cups are dense, and the headband frame is metal, which gives the headphones a solid build quality that shouldn’t be too damaged if dropped accidentally.
The Beyerdynamic DT 1770 PRO is a very good sounding pair of closed-back over-ear headphones. They have a deep, punchy, and neutral bass, an even and clear mid-range, and a good and well-balanced treble. However, their bass delivery is inconsistent across multiple users and sensitive to fit and seal, and their treble is on the bright and sibilant side. On the plus side, our test unit didn't measure as sibilant (sharp and piercing on S and Ts) compared to the rest of the Beyerdynamic's lineup like the DT 770 and the DT 1990 PRO. Overall, they are a versatile pair of critical listening headphones suitable for a wide variety of genres, from bass-heavy to vocal-centric music.
The Beyerdynamic DT 1770 Pro have a great bass. LFE (low-frequency extension) is at 10Hz, which is excellent. Low-bass, responsible for the thump and rumble common to bass heavy music and sound effects is quite well-balanced. Mid-bass responsible for the body of bass guitars and the punch of kick drums is also well-balanced and within 1dB of our target. High-bass, responsible for warmth, is within 0.3dB of our neutral target. However, their bass delivery varies significantly across users, and is sensitive to the quality of fit, seal, and whether you wear glasses. The response here represents the average bass response and your experience may vary.
The treble performance of the DT 1770 PRO is very good. Low-treble is even but has a small dip around 4KHz. Mid-treble, although a little overemphasized, is also even and well-balanced and doesn't measure as sharp on S and T sounds (sibilant) as the other headphones in the Beyerdynamic lineup.
The frequency response consistency is sub-par. In the bass range, the delivery across our 5 human subjects showed more than 12dB of variation at 20Hz, and about 6dB of variation at 100Hz. This is quite significant and noticeable. So depending on the shape and size of your head and whether you wear glasses, you may experience a drop in bass. The treble range delivery, however, is decently consistent across multiple re-seats, especially below 10KHz.
The Beyerdynamic DT 1770 PRO have great imaging. Weighted group delay is at 0.34, which is good. The GD graph also shows that the group delay response is almost entirely below the audibility threshold. This results in a tight bass and a transparent treble reproduction. Additionally, the L/R drivers of our test unit were exceptionally well-matched in frequency, amplitude, and phase response, ensuring accurate placement and localization of objects (voices, instruments, video game effects) in the stereo field.
The Beyerdynamic DT 1770 PRO have a sub-par soundstage. The PRTF graph shows a good amount of pinna activation, but the accuracy is quite low, especially around 5KHz. There is not a notch present in the 10KHz region either. This suggests a decently large soundstage that may be perceived as unnatural and located inside the listener's head.
The distortion performance of DT 1770 is above-average. The overall amount of harmonic distortion is quite good and similar to that of DT 770 in the mid and treble ranges. However, the spikes at 2KHz 4KHz were not present in our DT 770 and could make the treble of the DT 1770 a bit harsh and impure.
The Beyerdynamic DT 1770 PRO have an average isolation performance and can be used in moderately noisy environments but won’t be great in loud environments. They passively block more noise than the DT 1990 Pro thanks to their closed-back design, but they are still moderately leaky, especially at higher volumes. People around you might be able to hear what you’re listening to if your volume is too high for the environment.
The DT 1770 Pro have a mediocre isolation. These closed-back headphones do not have active noise cancellation and therefore do not isolate in the bass range. This means they will let in all the rumble of airplane and bus engines. In the mid-range, important for blocking out speech, they achieved about 12dB of isolation, which is above-average. In the treble range, occupied by sharp sounds like S and Ts and air conditioning systems, they reduce outside noise by 32dB, which is good.
The leakage performance is mediocre. The significant portion of their leakage is spread between 500Hz and 4KHz, which is a relatively broad range. However, the overall level of the leakage is not very loud. With the music at 100dB SPL, the leakage at 1 foot away, averages at 44dB SPL and peaks at 55dB SPL, which is just above the noise floor of most offices.
The Beyerdynamic DT 1770 PRO are wired critical listening headphones and do not have a battery, and do not have any app support for customization options.
The Beyerdynamic DT 1770 PRO are wired headphones that can’t be used wirelessly and do not have a microphone to be used with cell phones and consoles. Since they have a wired connection, they practically don’t have any latency and are great for watching video content or gaming.
They are simple wired headphones with a 1/8” connector but come with a 1/4" adapter as well. They only provide audio as there is no microphone on these headphones.
There is no charging dock or base for these headphones. For good headphones with a dock, check out the SteelSeries Arctis 7.
The Beyerdynamic DT 1770 PRO are well-built critical listening headphones. They are quite comfortable but might be too tight for some right out of the box. Their closed-back design helps deliver more bass than the open-back DT 1990 PRO, but more prone to inconsistencies. They look and feel premium, but their sound quality isn’t very different than the lower-end DT 770, and the DT 1770 are significantly more expensive, and the investment might not be worth it. See our recommendations for the best audiophile headphones, the best closed-back headphones, and the best headphones for studio use.
The Beyerdynamic DT 1770 PRO are better-built headphones than the Beyerdynamic DT 770 model thanks to their detachable cable, but overall, for the price difference, the DT 770 offer better value. Both sound signatures of these headphones are very similar, and their design is basically the same. You do get a big hard case and an extra straight detachable cable with the DT 1770, but that’s about it.
Both Beyerdynamic models are great critical listening headphones, but are better used in different environments. If you’re looking for a bit more punch and bass, the closed-back design of the Beyerdynamic DT 1770 PRO might be better suited for you. If you’re looking for headphones to listen to your favorite music at home, in a quiet environment, then the open-back Beyerdynamic DT 1990 PRO will give you better soundstage and a more speaker-like experience. For commutes and office use, the DT 1770 won’t leak as much as the DT 1990 by design.
The Beyerdynamic DT 1770 PRO are better-built critical listening headphones than the Audio-Technica ATH-M50x, but they come at a much steeper price. The sound quality is about the same, but the M50x have less sound consistency issues than the DT 1770. On the other hand, the padding of the Beyerdynamic headphones is softer and feels more comfortable, but they are tighter on the head than the M50x. The DT 1770 also isolate passively a bit more, but they leak more than the Audio-Technicas. The more low-profile design of the M50x might be better for outdoor use.
The Beyerdynamic DT 1770 PRO are better headphones than the Focal Elegia. They might not feel as comfortable as the Elegia because of their tighter fit, but they have great audio reproduction to reproduce tracks accurately. However, the Elegia are slightly better-built headphones but are also bulkier. Overall, the Beyerdynamics have better sound, are more versatile, and will still last you years.
The Beyerdynamic DT 1770 PRO are better headphones than the Shure SRH440 thanks to better build quality and better and more consistent bass delivery. However, they are way more expensive, and the Shure SRH440 are very comfortable headphones that offer great value for their price tag. They are all plastic, but if you’re looking for budget critical listening headphones, the SRH440 are a great pick for sound quality. On the other hand, the metallic frame of the DT 1770 feels more high-end, and they isolate a bit more noise than the Shures.
The Beyerdynamic DT 1770 PRO are better closed-back critical listening headphones for most people than the Focal Stellia. Their treble response is less veiled, and their bass response is slightly more balanced. They also come with additional ear cups and come with a longer, coiled audio cable. The Stellia do have a more premium look and feel, though, and come with a better carrying case. The Stellia are worth considering if you prefer their more premium design, but the DT 1770 PRO provide better value overall.
