Nothing that a night over a few books cannot lessen 
Doing some preventive measurements rn
The small cables don’t feel flimsy nor like they‘d break easily, but I‘m the kind of person who‘d rather be prepared in advance. I‘ll keep them and want them to last a long time. If they‘ll still fail in the future I can repair them anyway ^^
I feel like Mini XLR is a good choice and I can understand why they went with it. These are Professional Use Headphones first, music enjoyment second, and given that most if not all Professionals have and use 3-pin XLR it makes a lot of sense to use that kind of termination. It‘s also a rather rigid and solid connection type.
Regarding the Impedance, I‘m actually thrilled by that. They do not really change at all when given more power, and can be driven by literally anything. I love efficient designs, and at 48 Ohms / 100db SPL these are incredibly efficient, Focal levels of efficient.
I have to say, these are really damn comfy. Like having them on my head. They‘ll also keep my ears warm when out in Winter.
These are actually the first pair of Beyers that I bought, and also the first I really really like. I’ve heard a lot of Beyers but was always rather neutral towards them, neither impressed nor disappointed. My Brother has a Pair of DT 770, so I had a bunch of time to test those, and found myself to be kinda in the middle as well.
I‘m definitely having fun with the DT 700 Pro X. I hope my preventive measurements to keep them intact and enthusiasm speak for that, but I always have to say that ymmv ^^
Look at who the launch day review samples went out to on youtube. They were all pro audio focused people. I’m guessing that everything they did with these was focuses on fixing the gripes the pro audio community had with the 770 and 990 with consumers being an afterthought. I’m sure a bunch of “which impedence do I buy” questions from people with various weak audio interfaces influenced them introducing such an easy to drive version.
I’m almost positive customcans will do it, he had mentioned in youtube comments on a 1990 mod video about doing it for that model in the past.
Its a shame that the 177x are a redheaded stepchild from beyer, because the solution could be as simple as ordering that jack with associated connectors since beyer loves reusing small parts between headphones. I’ve never seen a picture of the internals of one of those so obviously, I could be wrong.
I‘d also like to give some more impressions on the sound:
These lack a very slight but of „punch“ that some might want, but I personally find that to be fine. On the other hand….
These are fast as fuck. So fast it‘s ridiculous for a DD. They honestly remind me of Planar Magnetics in that regard. That speed is especially apparent in fast electronic music or guitar strings for example.
The Dynamics, both Microdynamics and Macrodynamics, are really nice.
Sound Signature I‘d describe as neutral-bringt, with the brightness being on the tamer side
It sounds like the treble peak of past Beyer Headphones has been taken care of, and the overall Treble is now much smoother without sounding recessed or loosing on detail. Have yet to come across sibilance.
Even though they are neutral-bright, Bass is present (as it should be for a closed back) and has nice impact and texture. Gives it a ever so slight warm touch which can be decieving.
Bass is also very well controlled and precise in its attack. It does not bleed into the mids, on some tracks ever so slightly, but the separation is very good without loosing coherency. I like the Bass on these much more than, let’s say the 770 or 1770.
Mids are much more present compared to prior Beyer Headphones. They got a nice clarity to them. Quite honestly, that makes them both great for monitoring and listening to vocal performances.
I love listening to acoustic tracks, orchestra or rock on these. Makes me wanna listen more and more.
I mean, it does make sense to want to appeal more to your professional crowd in beyers case… they have quite the reputation.
not just that but what is the difference between impedance… it doesn’t help that beyers support lines fail to explain the differences if you ask them and if you ask them about the tygr they tell you the 990 is exactly the same… which is not even remotely true.
considering how easy these are to drive and the lack of scaling… I really dont see it necessary at this point.
demevalos tore one apart
thats a completely new set of internals, but looks super easy to mod since no soldering on the driver
Whoda thunk they’re like designed to be modded lol. That’s pretty cool.
Here’s some insight from Beyerdynamic on some of the design choices if anyone is curious.
Here’s the US Amazon listing for the 700 Pro X and 900 Pro X (and the new Pro X mics)
So thoughts on here initially. 900 pro x
New pads?
So the new pads are slightly less thick yet soft velour pads using the same material found in beyers DT series(not the ones like 1990 as those feel different the original cheaper ones). They are quite soft and fit rather snug around my ears… but aren’t particularly bad at all. Personally, I am a bigger fan of the original slanted thin pads compared to this as with these I can definitely feel I am wearing the headphone but they are still quite comfortable. My biggest complaint here is the clamp, the clamp is quite hefty in this and absolutely needs stretched straight out of the box I didn’t really like putting these on till I stretched them for some days. The pads use a different ring adapter here and appear to me that currently this headphone has zero ways of pad rolling which is a deal breaker to someone who likes to change his pads and see how it sounds
Cable: No complaint… standard 3 pin mini xlr… essentially same cable that comes with your DT 1990. Not a junk cable but of course you can always get a better one.
Power Requirements: Very low… weak units definitely won’t power this completely like I wouldn’t say something like a Syba Sonic or anything will be good for this… but your moderately strong units or strong motherboards and phone can drive this fine. Most of my amps were complete overkill… if it helps the asgard 3 is in high gain and its around… I want to say 8 oclock maybe less being comfortably loud so barely turned on
Scaling: practically nothing to speak on here… The headphone will take some characteristics such as extra spatial recreation from the asgard or some slight warmth out of the liquid platinum but its not really that drastic of a change that would be worth mentioning… These are simply find the right setup to drive them and use them… needless to say? I am disappointed
Build: nothing really to write home about here. It looks quite similar to the original 990. Typical metal mixed with plastic… but the housings are on the plastic side of things as is the top piece connected to the headband. Overall it feels rather plain in my opinion compared to what I am used to with other beyers however, it still has a rather sturdy build to it as one would expect from a beyer so I can’t really see these breaking less you get stupid with your headphones and throw them or something.
Soundstage: The interesting thing about this headphone is despite being open it feels rather closed at the same time the soundstage is of good size… its absolutely not as big as the T1 2nd gen but its closer to the tygr and DT 990 which is fine… too much soundstage can be bothersome anyway and this is somewhere between a bit intimate and rather large(my opinion on this will probably change a bit the more I use it and I am not done comparing between the beyers and other alternatives)
Sound signature: Now -this- is where it gets rather interesting
Lows: Seeing the pads and that filter I thought instantly are we going to get a bassy beyer? The answer? absolutely not, infact this sounds so remarkably close to neutral that it surprised me. It sounds rather rounded off unlike the 1990 which has that planar like slam to it and reminds me of my T1… I had to pick back up my T1 to confirm that actually. Nonetheless, it still hits harder and drives deeper than I get from a Sennheiser which is fine(however sennheiser can become quite bassy through the right setups like the ifi zens or tubes of course but were talking stock sounds here)
Mids: pretty forward, clear, very transparent, and what caught me off guard the most from a beyer. The mix between this, the rather neutral lows, and the upper frequencies really make this headphone in my opinion and gives this a special place in beyers lineup giving it unique character. There was a slight haze when I first started using them but with some time here that cleared up. I did notice some changes between amps here so just something to note. The mids sound very similar to the 880 here making me feel this is definitely a more mids headphone which is fine considering I know many love the 880 when it comes to mid frequencies… that isn’t to say they are the same… I do still think the 880 represents the mids a bit better but -only- when its driven at 600 ohms with high quality setups
Highs: What’s a beyer without its treble? Looks like beyer wanted to keep their house sound while dialing it back a lot due to community feedbacks. While still raised I find it a bit harder to call this bright in terms of Beyerdynamic specifically. It’s definitely raised but so comfortable and I find it hard to say this has sibilance… the highs sound extremely smooth and very well controlled to not peak into uncomfortable territories at the same time that typical beyer aggression that forces you into that treble I can’t seem to find here… the treble is there, its brighter, yet stays in it’s lane like it’s supposed to.
Detail: The upper treble does bring some detail to the table here… and the headphone itself is pretty heavily detailed and rather analytical in its own right… though I wouldn’t say its anywhere near as analytical as its big brother 1990. This feels like a straight middle ground headphone in the lineup
Separation: If you used the 1990 then you should get how well this can separate its sounds… kudos to that beyer, wasn’t expecting good results from a low ohm driver
Imaging: spot on but not as good as the 1990 somewhere on the tygrs level here to my ear so far but I will be doing further testing
Price point: this is… rough for me. I think its unique to have this kind of headphone from beyer at the same time… the price is a bit steep. I think if your looking for a good highly detailed brighter headphone that can potentially replace your sennheiser(maybe the 560s) due to perhaps you just didn’t like the comfort, maybe you felt the bass lacking, or something along those lines this would be a solid choice. However, for analytical work… the price is dangerously close to what you can fetch a DT 1990($350 - $400 on used markets mint), you can get the T1 2nd gen which I feel can demolish this headphone in many areas at $400, and at the same time for those who like more relaxing mids and highs… your still in the ballpark for Sundara so the price point has some rather heavy competition here. All the while you can still get most of this just from the DT 880 as the two are pretty similar just this is more open.
Initial thoughts so far on it but I am being rather critical in some places
im assuming you were referencing the 900 Pro X (you mention open back), but it wasn’t 100% clear
Fixed. Sorry lol yea 900
No worries man, thanks for the in-depth look. BTW any plans to look at the 700 Pro X?
I do soon actually. I want to spend some time with this first. I’ll be putting the order in tomorrow
These seem like ‘prosumer’ category. Just plug in and not worry too much about amplification but still get good sound regardless of chain. Maybe these are meant to be the “upgrade” from the dt770s people usually wear for podcast/streaming/youtube and etc.
The improved mids from previous models sound promising.
Just too bad there isnt a 600 ohm model that scales.
Thanks to everyone for the impressions.
Personally I’m okay with a more balanced beyer. Easy to drive, non offensive, plenty of detail, good comfort. For those who like streaming these could be fantastic since they wouldn’t need an amp in most cases.
Though I would love a 600 ohm or hell 250 would be alright too. Something that will scale and get along with tubes. Let me pad roll my headphone too beyer…
Then again, if I had to choose this or like… elex? I’m going with elex on mids
The 900 Pro X is quickly turning into a headphone I would pick up for my partner. Simple to power with a Magni etc, neutral sound and not overly sharp (I love the Beyer house sound but it ain’t for everyone)
@Alfredo3001 Have you tried pressing on the earcup? Maybe it isn’t all the way snapped in? Also the earpads are real easy to take off if you need to take a look at it.
