The Beyerdynamic DT 770 PRO are closed-back, over-ear studio headphones handmade in Germany. Thanks to their closed-back design, they're more versatile and have a slightly better bass response than the Beyerdynamic DT 990 PRO or Beyerdynamic DT 880. They're intended to be sturdy and durable for professional or critical listening applications. They come with a padded headband and velour earpads to make them comfortable for extended listening sessions. This combination of great construction, comfort, and closed-back design means they're an industry-standard model found in recording studios worldwide.
Our Verdict
The Beyerdynamic DT 770 PRO are good for neutral sound. Their sound is ideal for professional use, thanks to flat, smooth mids, which ensure clear and natural vocals and instruments. If you like thumpy, rumbly bass, you may be disappointed by their bass roll-off, though. This range is also a little inconsistent between sittings, so it's important to ensure a good fit each time you use them. There are a few peaks and dips in their treble range, too. Vocals and instruments can be alternatingly dull or piercing, depending on their frequency, while sibilants like cymbals are piercing. They don't have the spacious soundstage either, but that's to be expected from closed-backs.

The Beyerdynamic DT 770 PRO are wired-only headphones; you can't use them for wireless gaming.
The Beyerdynamic DT 770 PRO are mediocre for wired gaming. They lack a microphone, so you'll need a standalone microphone to input audio. If you already have a mic (or don't need one), their sound is ideal for dialogue and musically-rich gameplay. They don't deliver as much bass as dedicated gaming headsets though, and this may be a downside if you're looking for a really thumpy, rumbly sound from sound effects like explosions.

Differences Between Sizes And Variants
The Beyerdynamic DT 770 PRO come in three variations with different impedances. Generally, higher-impedance headphones require more output from the connected device to produce audio at listenable volumes. We tested the 250-ohm version, which Beyerdynamic recommends for use in the studio with professional devices that provide additional amplification. They recommend the 80-ohm version for general studio use and the 32-ohm model for mobile devices like laptops and smartphones. These headphones are also offered in a 'Limited Edition' version featuring black earpads. If you find other variants, please don't hesitate to let us know in the comments.
Compared To Other Headphones
The Beyerdynamic DT 770 PRO are closed-back reference headphones well-suited to professional and critical listening applications. They offer a comparable sound performance to other closed-back headphones from this manufacturer, like the Beyerdynamic DT 700 PRO X and Beyerdynamic DT 1770 PRO, at a lower price point than these premium offerings. They lack a detachable cable, meaning you'll have to replace the entire pair if it fails. The Audio-Technica ATH-M50x come with a detachable cable and are a good choice for users who find the treble response in Beyerdynamic headphones to be fatiguing. Those who prefer a wider, more expansive soundstage with a more comfortable fit and don't care about audio leakage will want to try the open-back Beyerdynamic DT 880 and Beyerdynamic DT 990 PRO.

The Beyerdynamic DT 770 PRO are better headphones for neutral sound than the Sony MDR-7506. The Beyerdynamic have a better build quality and a more comfortable, stable fit. Their bass response is more neutral, and they have a much better passive soundstage performance. However, the Sony leak much less audio.
The Audio Technica ATH-M50x and the Beyerdynamic DT 770 PRO have very similar performance, but some might prefer the better build quality of the Beyerdynamic. Their metal frame feels sturdy, and the soft padding fabric feels nice on the skin. However, they can be tight for some, especially if you have a larger head. They might also sound a bit sharp for some and don't come with as many cable options as the Audio Technica.
The Beyerdynamic DT 770 PRO are more neutral-sounding headphones than the Beyerdynamic DT 700 PRO X. The 700 PRO have a more neutral mid to treble range. As a result, vocals and lead instruments sound full, present, and detailed. However, sibilants still sound bright and piercing on both headphones. Fortunately, both of these closed-back headphones have the same quality manufacturing and comfortable build.
The Sennheiser HD 560S and the Beyerdynamic DT 770 PRO are meant for different applications, so which is better is determined by your needs. The Sennheiser are open-back headphones with a much better passive soundstage performance. They're much more comfortable and have a more consistent bass delivery. On the other hand, the Beyerdynamic have a closed-back design, which supplies more low-end. The headphones leak less audio, and they isolate you from a bit more ambient sound, so you can wear them in noisier spaces than the Sennheiser. They also have a significantly better build quality.
The Sennheiser HD 600 and the Beyerdynamic DT 770 PRO can both be considered as audiophile options but have very different strengths. The Sennheiser have an open-back design. Their passive soundstage is much more open and spacious-seeming, and they have more consistent bass and treble delivery, but their sound lacks a bit of low-bass. On the other hand, the Beyerdynamic are closed-back headphones with a more prominent bass range. They have a much more comfortable fit, isolate you from more ambient sound, and leak less audio. As a result, the Sennheiser are a better fit for analytical listening applications, like sound mixing or editing. The Beyerdynamic are great if you value some passive noise isolation and want a bit more rumble in the low end.
The Sennheiser HD 599 and the Beyerdynamic DT 770 PRO are both impressive audiophile headphones, and you may prefer either. The Sennheiser are open-back, so they deliver less bass but have an otherwise very balanced, clear sound and open soundstage. The Beyerdynamic are closed-back, so their sound profile can differ slightly from person to person. They generally get much more bass but can also sound sharp.
Both the Sennheiser HD 650 and Beyerdynamic DT 770 PRO are good critical listening headphones, but the Sennheisers are open-back, which could make them sound more open-sounding. The Sennheiser are also a bit more comfortable, but they don't have the nice and sturdy build of the Beyerdynamic. Additionally, the Beyerdynamic have a better sound profile, notably because of their closed-back design, which helps with a fuller-sounding bass. Their closed design also blocks more ambient noise and leaks less than the Sennheiser.
The Beyerdynamic DT 770 PRO and Beyerdynamic MMX 300 (2nd Generation) are both capable over-ears by the German manufacturer. The DT 770 PRO are aimed at analytical listeners and, depending on the variant, may need a headphone amp. They have a fairly neutral frequency response that spikes in the highs. They have velour ear pads, a wired-only connection, and passive isolation. Meanwhile, the MMX 300 (2nd Generation) differ most obviously with the inclusion of a non-removable microphone. They have additional in-line controls as well. Their tuning is similar, with slightly more low-end and a larger spike in the highs. They're bulkier with better headband padding.
The Beyerdynamic DT 770 PRO are better over-ear studio headphones than the AKG K371. The Beyerdynamic have a more stable fit and feel more durable. While they both have very well-balanced sound profiles, the AKG are slightly more accurate, but their fit is more prone to inconsistencies among users. On the upside, the AKG leak considerably less audio.
The Beyerdynamic DT 770 PRO are better for neutral sound than the Beyerdynamic DT 900 PRO X. While both headphones are comfortable and well-built, the 770 PRO are closed-back headphones with a more neutral and well-balanced bass and mid-range. They can also block out more background noise, which you may prefer if you listen to audio in a moderately noisy environment. However, the 900 PRO X are open-back headphones that create a more spacious and open passive soundstage.
The Beyerdynamic DT 770 PRO are slightly better than the Audio-Technica ATH-M40x. The Beyerdynamic have a slightly more accurate overall sound signature, but they can be slightly too sharp and piercing. On the upside, they're noticeably more durable than the Audio-Technica, thanks to their full-metal frame and large ear cups. If your budget allows it, go for the Beyerdynamic unless you're sensitive to higher frequencies.
The Beyerdynamic DT 770 PRO are better headphones for neutral sound than the Sennheiser HD 280 Pro 2016. The Beyerdynamic have a more balanced sound profile overall, although some people find the peak in their treble slightly sharp. By contrast, the Sennheiser have a veiled treble response that can make your mixes sound a little muffled and lacking in high-end detail. The Beyerdynamic are also much more comfortable than the Sennheiser, and their build quality is noticeably superior. The Sennheiser leak less audio, so they'll be better suited for quiet office environments.
The Beyerdynamic DT 990 PRO have a more detailed sound and a more immersive, wide soundstage than the Beyerdynamic DT 770 PRO, thanks to their open-back design. That said, the DT 990 PRO feature a more prominent bass response that's well-suited to bass-centric genres like EDM and hip-hop. They also leak less audio. Both headphones are similarly built and are comfortable; choosing between them really comes down to whether you're in the market for open-back or closed-back headphones.
The Beyerdynamic DT 1770 PRO are better-built headphones than the Beyerdynamic DT 770 PRO 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 get a big hard case and an extra straight detachable cable with the DT 1770, but that's about it.
The Beyerdynamic DT 880 and the Beyerdynamic DT 770 PRO are similarly-performing headphones for critical listening. The DT 880's semi-open design creates a slightly more open soundstage. They're also more comfortable and have a more consistent frequency response. However, the DT 770 PRO have a more even sound profile overall, provided you achieve a good fit, and they leak less sound.
The HyperX Cloud Alpha and the Beyerdynamic DT 770 PRO are very different pairs of headphones. The HyperX are gaming headphones, while the Beyerdynamic are designed for critical listening. Therefore, the HyperX are a better choice if you want a microphone, and they're also more comfortable and feel more durable. On the other hand, the Beyerdynamic have a better-balanced sound profile, though not by much.
The Beyerdynamic DT 770 PRO and the Philips Fidelio X2HR are audiophile headphones with different strengths. The Beyerdynamic are better-built headphones with a closed-back design. They do a better job reproducing the thump and rumble of low bass. They also leak less audio and passively isolate you from more sound, although they aren't ideal for noisy environments. On the other hand, the Philips are open-back headphones with a much better passive soundstage performance. They're also much more comfortable.
The Beyerdynamic DT 1990 PRO are marginally better neutral sound listening headphones than the Beyerdynamic DT 770 PRO thanks to their open-back design that allows them to create a much better soundstage. That being said, the closed-back design of the 770 PRO means they block more sound and leak less audio, though they still are sub-par in both these regards. The 770 PRO also have a slightly more accurate sound profile, especially in the bass range. Other than that, both headphones are comfortable and feel very well-built.
The Philips SHP9500 are marginally better headphones for neutral sound than the Beyerdynamic DT 770 PRO. The Philips are open-back headphones with a much better passive soundstage performance. They're also much more comfortable and breathable. On the other hand, the Beyerdynamic have better build quality, a much more stable fit, and a more neutral bass response. Thanks to their closed-back design, they also isolate you from a bit more ambient noise and leak less audio.
While both headphones are well-made and comfortable, the Beyerdynamic DT 770 PRO are better for most people than the Sennheiser HD 620S. The Beyerdynamic have a more consistent frequency response, translating to a more predictable sound profile regardless of your head shape or if you wear glasses. Their sound is both brighter and bassier than the Sennheiser, though both headphones isolate out noise similarly. On the other hand, the Sennheiser are more comfortable with fewer exposed wires, and you can replace the detachable cable.
The HiFiMan Sundara 2020 are better for neutral sound than the Beyerdynamic DT 770 PRO. The HiFiMan have an open-back design. They're more comfortable, deliver sound much more consistently, and have a much more open, spacious soundstage. On the other hand, the Beyerdynamic are closed-back headphones so they can reproduce more bass, and ensure your music has more thump and rumble, which some may prefer. They're also more breathable and have a better build quality.
The Beyerdynamic DT 770 PRO and the Sennheiser HD 660 S are somewhat comparable over-ear headphones with slightly different sound signatures. The Sennheiser have a small dip in the treble range that can make vocals sound slightly veiled, while the Beyerdynamic have a peak in the high-treble that can make cymbals and sibilants sound piercing. At the other end of the spectrum, while the Beyerdynamic have superb bass that accurately conveys the thump and punch of kick drums, the Sennheiser are slightly lacking in this area. That's to be expected as the Sennheiser are open-backs, which typically have less bass than closed-backs like the Beyerdynamic. That design different also means the Sennheiser have a more open passive soundstage than the Beyerdynamic.
The Beyerdynamic DT 770 PRO are slightly better closed-back critical listening headphones than the Sennheiser HD 598 Cs. Their sound profile is somewhat better, but they may sound overly sharp for some people. The Beyerdynamic are very well-built headphones and feel more durable than the Sennheiser. Both headphones are fairly comfortable, but the Sennheiser's cups are more spacious. The Sennheiser also have an in-line microphone for calls, which can be useful if you want to take calls on the go.
The Sennheiser HD 820 are slightly better closed-back critical listening headphones than the Beyerdynamic DT 770 PRO, but not by much, especially considering the price difference. The Sennheiser have a much better and more premium build quality. They also have more spacious and well-padded ear cups that are breathable enough to wear for much longer than the Beyerdynamic. They come with more high-end cables and accessories and don't sound as sharp on vocals and instrumentals as the Beyerdynamic. On the other hand, the Beyerdynamic offer a better value for their price with a more consistent bass reproduction and a fairly even and neutral mid-range. They're also decently well-built and comfortable enough for most, although they can be tight on the head for some.
The Beyerdynamic DT 770 PRO are better over-ears for neutral sound than the RØDE NTH-100M. The Beyerdynamic are better built, deliver audio more consistently across different re-seats, and have a more neutral sound profile, which some users may prefer, and their passive soundstage is more immersive. They also block out more ambient noise passively. However, the RØDE have a detachable audio cable, and the '100M' model come with a detachable mic if you want to use them for gaming.
The Beyerdynamic DT 770 PRO are better closed-back headphones for neutral sound than the Focal Celestee. The Beyerdynamic have a more neutral default sound profile, a significantly better passive soundstage performance, and are somewhat less prone to inconsistencies in their audio delivery. However, the Focal have a significantly better build quality that reflects their high-end materials and are more comfortable.
The Beyerdynamic DT 770 PRO are better audiophile headphones than the 7HZ Timeless. If you prefer over-ears, the Beyerdynamic have a more comfortable fit, a better build quality, and a more neutral sound profile. Their passive soundstage also feels more out-of-head and wide. However, the 7HZ are wired in-ears that are more stable, and have significantly more consistent audio delivery. They also leak less audio at high volumes.
The Beyerdynamic DT 770 PRO and the Astro A40 TR Headset + MixAmp Pro 2017 are designed for different purposes but are both fairly versatile. The Beyerdynamic are simple studio headphones designed for critical listening, while the Astro A40 provide a customizable gaming experience. However, the Beyerdynamic can be a viable option for gamers who don't need a mic, while the Astro are also a decent choice for mixing podcasts or live streams. The biggest difference is in their sound profiles - the Beyerdynamic sound quite bright, even piercing to some, while the Astro sound less sharp but are also a bit dark. The Astro have many customization options, so you can more easily tweak their sound profile to better suit your tastes.
The Beyerdynamic DT 770 PRO and the TOZO T6 Truly Wireless are very different headphones. The Beyerdynamic are wired headphones designed for critical listening in the studio, while the TOZO are truly wireless earbuds for casual everyday use. The TOZO support Bluetooth for wireless freedom on the go but have too much latency for studio use.
The Astro A50 Gen 3 Wireless 2017 are better headphones for gaming than the Beyerdynamic DT 770 PRO. The Astro aren't as tight as the Beyerdynamic and have a more accurate audio reproduction. Also, while the Astro are wireless, the latency is negligible, although not nonexistent like the wired Beyerdynamic. The Astro also have a microphone, which the Beyerdynamic lack. If you have a stand-alone mic or you don't need one, the Beyerdynamic is a good-sounding wired option.
Test Results
The Beyerdynamic DT 770 share a similar design to the open-back Beyerdynamic DT 990 PRO. They have the same circular plastic ear cups and a thick metal frame with a removable cushion strap. They have a matte, black finish with plush gray velour earpads. There's also a 'Limited Edition' variant with black earpads for a sleek, all-black look. It's worth noting that these earpads are easily replaceable, and you can buy both colors directly from Beyerdynamic.
The Beyerdynamic 770 PRO are decently comfortable to wear for short periods and are amply padded. The ear cups are covered with a soft microfiber fabric that feels nice on the skin and fits well around most listeners' ears. Unfortunately, like the Beyerdynamic DT 990 PRO, they clamp the head a bit, which gets uncomfortable after a while—especially for those with larger heads.
The Beyerdynamic DT 770 PRO, like the Beyerdynamic DT 880 and Beyerdynamic DT 990 PRO, aren't portable headphones. They're not designed to be portable and are best suited to home or studio use. The ear cups don't fold or lay flat, and although they have a relatively compact build for an open over-ear model, they're still too bulky and cumbersome to carry on you without a bag.
These headphones come with a simple pouch that will protect the headphones against scratches and minor water exposure. However, it won't shield them from drops or impacts.
The Beyerdynamic DT 770 PRO are durable and sturdy headphones. They have the same solid metal frame as Beyerdynamic DT 990 PRO, and the ear cups are dense enough to handle drops without getting damaged. However, the ear cup enclosures feel a bit plasticky, especially compared to the premium build and feel of the Beyerdynamic DT 880's ear cups.
The Beyerdynamic 770 PRO are tight enough on the head that they won't fall during casual listening sessions unless the non-detachable cable gets hooked on something. However, they're too bulky to run with comfortably. The large ear cups will slide off your ears under high physical activity, so like most critical listening headphones, they won't be ideal for taking to the gym.
The Beyerdynamic DT 770 PRO have a neutral sound profile, which results in an accurate reproduction of vocals and lead instruments. Their sound is also suitable for a variety of audio content. However, like many headphones this manufacturer offers, the sibilants are a bit bright and piercing. They also lack some thump and rumble in their bass.
It's worth noting, however, that Beyerdynamic currently produces three variants of this model: 32-, 80- and 250-ohm variants. We tested the 250-ohm version, which is most suitable for professional end applications, where the drivers benefit from additional amplification. We tried using these headphones on an Android phone instead of through our usual headphone amp and noticed that they lacked a lot of bass. Beyerdynamic advertises the 80-ohm version as a universal studio use headphone, and the 32-ohm version is aimed at more mobile applications. While we haven't tested these variants, users who primarily listen to audio through a smartphone or laptop might find their music sounds better (and louder) with the 32-ohm version.
These headphones have okay frequency response consistency. The bass range is quite inconsistent across different users. In particular, those who wear glasses might notice a reduced bass response as the headphones struggle to provide a tight seal. They're also a bit inconsistent in the treble ranges, so you might notice a difference in response based on how you position them on your head.
The Beyerdynamic DT 770 PRO do an excellent job of following our target curve in the bass range. Overall, the response is a little underemphasized compared to our target, so tracks with 808s can feel light on thump and rumble. that said, a bit more high-bass helps add warmth back into the mix. If you enjoy a more bass-heavy sound overall and are looking for a more casual, wireless design can check out the Sony WH-XB910N Wireless.
The mid accuracy is outstanding. The response is virtually flat, allowing for extremely accurate reproduction of vocals and lead instruments.
The Beyerdynamic DT 770 PRO don't follow our target curve quite so well in the treble range. A subtle under-emphasis in the low treble causes vocals and lead instruments to lose a little of their brilliance. As with other headphones in the Beyerdynamic lineup, there's a noticeable bump in the mid to high-treble that causes sibilants like cymbals and whispery vocals to sound harsh and piercing. Even though this can sound fatiguing over time, some people may prefer this sound as it can help emphasize imperfections in your mix.
These headphones have a decent peaks and dips performance. While the response is generally even, the slight dip in the mid-bass removes some body from instruments and vocals. In the treble range, there are a few peaks and dips that cause vocals and instruments to be alternatingly harsh or veiled, depending on the frequency. Sibilants like cymbals also err on the side of piercing.
This manufacturer has developed a reputation for producing headphones with solid imaging performance, and the Beyerdynamic DT 770 PRO are no exception. Our unit's group delay response is entirely below the audibility threshold, resulting in tight bass and transparent highs. The L/R drivers are very well-matched in phase, frequency, and amplitude response, creating an even and stable stereo image so you'll easily locate objects (instruments, voices, footsteps) within the stereo field.
The Beyerdynamic DT 770 PRO have a mediocre stereo soundstage performance. While you'll perceive the soundstage as decently sized, the sound appears to come from inside your head instead of around you—a common feature of closed-back, over-ear designs. Those who prefer a more open soundstage performance and are comfortable with some leakage can check out the Beyerdynamic DT 990 PRO. They're essentially the same headphones but with an open-back design that naturally creates a more immersive soundstage performance.
These headphones have great weighted harmonic distortion performance. Even at high listening volumes, they produce clear and pure audio with only very slight peaks in the high-bass range. At normal volumes, there's an even response across all frequency ranges.
These are the settings used to test these headphones. Our results are only valid when used in this configuration.
The Beyerdynamic 770 PRO have a poor noise isolation performance. They isolate passively using their closed-back ear cups design but aren't the most effective at blocking out background noise like traffic or construction. They can reduce some mid range noise like ambient voices, but it isn't enough for a busy office.
These headphones also don't fare well when isolating against common scenarios either. You'll hear most of the rumbles of airplane engines or traffic on a busy street. They also have a hard time reducing noise in a typical office setting.
These headphones have a disappointing leakage performance. The main issue is that the leakage spans a broad range across the mid and treble ranges. If you play music at a high volume, these frequencies are the most likely to leak into your environment. In environments like an office, this level of leakage will be audible to others nearby. For those in a noise-sensitive environment looking for reference headphones that leak less, it's worth checking out the AKG K371 instead.
These headphones come with a non-detachable TRS cable with a standard 1/8" jack and a 1/8" to 1/4" adapter so you can plug into devices like soundcards. The lack of a detachable cable means that any breakage in it or the jack will require you to replace the headphones themselves rather than just the cable. To compare, the added luxury of a removable cable, like on the Sennheiser HD 620S, can extend the lifespan of your headphones and allow you to customize the overall cable's length with aftermarket options.
You can use these headphones wired on PlayStation if you plug their 1/8" TRS cable into a controller. However, you'll need an external microphone to input audio.
You can use these headphones wired on Xbox if you plug their 1/8" TRS cable into a controller. However, you'll need an external microphone to input audio.
