Beyerdynamic DT 1770 PRO Headphones Review

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.

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. If you're looking for a more compact storage solution, the Beyerdynamic DT 700 PRO X come with a nylon pouch that's easier to store but doesn't offer the same level of protection.

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.

These headphones are tighter on the head than average, which makes them stable, but they might be too bulky to exercise with. They won’t fall off your head during listening sessions, but like most critical listening headphones, they aren’t a great pick for sports and to wear at the gym.

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 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 mid-range is great. The response is even and flat, suggesting a clear and well-balanced reproduction of vocals and lead instruments. The subtle 2dB tilt favoring lowering frequencies won't be audible to most people.

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 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 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.

These headphones do not have a microphone so the recording quality has not been tested.

The DT 1770 PRO are simple wired headphones. They use a 1/8” connector so they don't have microphone support, but do do but come with a 1/4" adapter as well. Their wired connection also provides a lag-free experience which makes them suitable for watching videos and gaming.
