beyerdynamic DT 770 PRO X Limited Edition

Loving these for the price. Great accomplishement by Beyer. Of course immediately EQ-ed them, I hope the Beyer Peak does not need to be mentioned, but it is exactly why I wanted it, this gives it character. The Sundara was too boring.

Impressions right from the honeymoon phase, so ymmv. Listening with a relatively bad Jazz recording in ALAC encoding through a Mojo2, so to peel out flaws easier.

Dt 770 Pro X Ltd vs Moondrop Chu 2
While the Chu2 had great resolution overall, especially considering its price tag, they pained the ears, they almost never sealed, even with the AZLA SednaEarfit and sound overall sounded in the league of an Apple Earbud, which is not a bad thing. It is just no comparison.

Dt 770 Pro X Ltd vs Shure Aonic 5
They CAN be compared to this sound. The Shure sealed for me. But... not always (which annoyed me a lot) and the sound of the Shures are darker. Soundstage of course denser, since its an IEM. Overall I did not feel I get enough for my money with the Shure Aonic 5s.

Dt 770 Pro X Ltd vs Sundara
The Sundara are also very light, but the Beyers feel nicer to my head, the 770 Pro X Ltd are also extremely light, lighter than the 700 Pro X. The Sundara got more Subbass, but more muddy tops and more muddy everything, slurpy, slower. Since they are open, the Sundaras should have a wider Soundstage, but they dont. The Sundaras leak a ton of sound, more than necessary. While I liked them, they just did not feel right to my head and to my ears. Hifiman is just not my style. Sorry to say, but I boycott Chinese products as much as possible, b/c of state-sponsored organ harvesting the Falun Gong practitioners, Google it, it is on par with Third Reich practice. Back to topic (to me sustainability is also part of topic), overall Sundaras go deeper but Beyers are more open. These are 2 comparable headphones with completely different emphasis, the Sundara in the low end and the 770 Pro X Ltd in the Top End.

Dt 770 Pro X Ltd vs 1990
Well, well. I love the 1990s. The 1990 have less resonance and feel more substantial, physically and from a sonic standpoint. But the 770 Pro X Ltd hint at the 1990s soundstage. Voices of the 770 Pro X Ltd are great and the mids are there, not to say I didnt EQ the Beyer-Peak. The 1990 have less peak, are more open, much more open and leak littler sound than Sundaras. The 770 Pro X Ltd seal nicely, but as they only provide a light plastic shell, I guess the 1770 leak less. The 770 are lighter and feel well build, but not nearly as premium built as the 1990s. For the asking price of half of the 1990 the 770 Pro X are fairly priced. Could they have priced them cheaper? Yes.

Jazz
Still Blunted - Jazzbois
This is a beautiful recording but less in terms of sound quality, more in terms of music. Since imho it is a bad recording I tried it to see how the 770 Pro X Ltd performed against above competitors, but the Beyer did not fall short, it still made the Music enjoyable enough, while revealing the recordings flaws to me.

Yussuf Dayes - Live from Malibu
The Top End in this album is exciting and very very well recorded and the 770 Pro X Ltd. brings this out beautifully. It is just no comparison to all above headphones except maybe the 1990s.

HipHop
Hooli Hansen II - Da Flyy Hooligan and Soles Of Mischief
Voices are surprisingly well in the 770 Pro X Ltd. Well done Beyer imho, but could be that the recording just shines here.

Film
House of Dragons
Still EQed the 770 Pro Ltd. The clarity of voices, the birds, the wind noises, the white noise of the film production, the bass when the candles burn. This is just excellent. I think I am a Beyerdynamic admirer now, exactly for reasons of revealing flaws and clarity, so keep in mind, without that Beyerpeak EQ-ed your ears are likely to develop a tinitus at the blink of an eye.

I used them without my amp directly on the MacBook Headphone Jack and the sound was still above just enjoyable, it produced the same characteristics as with the amp, but less pronounced. However with that Beyerpeak you wont survive long, non-EQed. Could work for my purpose of short non-eq-ed mixing sessions in Cafes or the University Library.

I just got a pair of the new DT770 Pro X headphones and here's a quick summary until measurements are done. I purchased this preview version myself, so no conflict of interest if you buy one or not. More photos attached to the post, so it doesn't clutter things up. I've had every Beyerdynamic model for my business, so have a good perspective having had the chance to use over 300 different headphones and IEMs. Lacking test equipment, I'll give lots of comparisons to popular models. In a nutshell, these sound the most like the Truthear Zero Red but with 2db-3db recessed mids around 600hz and a fairly aggressive treble climb up to where snare drums hit and female vocalists go into higher ranges. Vocals and acoustic instruments like violins don't have the same lush/full sound like they do on the Truthear Zero Blue version, Sennheiser HD600/650, or Thieaudio Ghost, which is as nice as the Sennheiser HD650/6XX at a much better price.

To test them, I used:
SMSL DO400
Topping D10b + SMSL Drop HO150x
Moto G Power phone with and without Apple 3.5mm to USB adapter
16 bit 44.1khz FLAC
Destiny 2
I test everything in it since the sounds are so familiar after years of playing, and just keep a solo player clan for getting engrams each week.

The Moto G Power did get them loud enough at max volume, but they sounded really good as long as you don't need headroom to equalize or party level volumes. With the Apple adapter it was unlimited volume and sounded terrific with FLAC files. On the DO400 and the temporary stack I pulled out they got better, but not night and day better. These really can do well with less power as long as your source files are good (i.e. lossless). I just ran in Windows exclusive mode for each test on the PC. My advice is just get a $9 Apple adapter on these. You won't need more power than that, even if you equalize with a preamp reduction. The main worry is their power handling is 210mw which is 1/5th of it's older brothers, so be really careful not to leave an amplifier in high gain mode or they might go up in a puff of smoke.

Imaging is excellent on these, as good as the Sennheiser IE600, in Destiny 2 I could instantly identify an enemy behind me. If anyone asks for a closed back gaming headphone, this is my new recommendation. Soundstage is on the money, not fake big or too small, just like the DT770 or MMX300. The only downside for gaming is the dip in the male vocal range is where footsteps can happen also, so a 3db boost at 600hz might be needed if you yearn to hear the pitter patter of little enemy feet in all situations.

For music, the bass is present and extends way down, but doesn't bleed into the mids or sound overly boosted. It's there if the song calls for it, but the DT770 250 ohm still pounds with more authority than these do in the bass department. For those bass obsessed, just get the Artti T10 and you'll be bouncing in your chair to hip hop songs. These aren't going to make you vibrate out of your chair like a hovercraft from the bass response.

Mids are a mixed bag. Male vocals are recessed and somewhat distant, with a hollow sound at times, not sure if it's the ear cup resonance or the kind of pre/post ringing in the 32 ohm DT770 with those drivers. It'll take measurements by someone with the equipment to analyze it. On the DT770 250 ohm it's not present though. Female vocals are good except when singers like Ellie Goulding or Sia go into their higher ranges and then it's higher/louder than they usually sound. It's not shouty or sibilant, but on the edge of too bright/thin at times. Amy Lee from Evanescence and Adele weren't as affected. If you value vocals and stringed instruments like violin, cello, etc. you'll be a lot happier with the Thieaudio Ghost for less money, or the Sennheiser HD650/600 for more (or used for the same price).

Treble: It's a Beyerdynamic, but it's not the dread peak like the DT990 600ohm I keep around for testing. It's a little bright, but the sound is the climb from mids to treble seems pretty aggressive. Songs with a lot of snare drums get annoying, I'd bet that where it peaks. The rest is detailed and sounds good, and higher treble isn't absent of air, but its not emphasized either. I think they played it fairly safe with the tuning.

Overall, it's better than the MMX300, DT700 Pro X, and 32 ohm DT770 but not as much fun as the DT900 Pro X. For closed back headphones I'd recommend them for a gamer who likes music and just wants one pair. For music fans, it's really if your library isn't focused on vocals and acoustic instruments. The drivers are fast and for EDM or rock it's very good. These are not going to fit every genre of music though. The Thieaudio Ghost is better for music, just not as good for gaming. I have a Sennheiser HD650 and it's still kingpin for acoustic and vocals along with the HD600.

They fit the same as other models, pads are the same traditional velour from the original DT770. The shells seem a little thinner plastic if you tap on them. They still feel solid with the same slider adjustment but it feels smoother and less clicky. The cable is the 9ft mini XLR, but a shorter one for travel would have been a good idea. These are compatible with the other 3 pin mini XLR cables.

I'm going to stick with my Hifiman HE5xx for a daily driver, but it was really nice to have a new favorite closed back pair to recommend to casual or serious gamers. For specific music that's not vocal or acoustic focused it would be fine. The DT177x would be better for most music though if closed back is the requirement. Noise isolation was as good at the DT770, which will block a central AC sound or a computer fan, but not much more like a landscaping crew rolling past. Overall, they're excellent for gaming, but for music they require equalizing, most won't be happy with them out of the box. They have good potential though if you don't mind tuning them with EQ.
