I received mine yesterday morning, but couldn't listen much yet. Also I'm a beginner in terms of serious listening, but always had a Beyerdynamic headphone for gaming/ movies, which is the reason why I thought to get this one (besides having the possibility to replace the cable easily). I only listened to a couple of songs from different genres each so far. I noted some impressions out of the box and without going back and forth to the standard version:

• Clamp pressure is less than standard DT770. Especially for my small head, but very comfortable.
• DT770 sound "signature" is kept.
• Treble might be too much for some people, but partially I was also listening too loud. When i reduced the volume and played some Fleetwood Mac the treble was fine for me. I checked with a volume meter (app) and the reduced volume, it showed averaging 67dB, max 75dB. Maybe I was listening too loud? Maybe it is dependent on the genre/track?
• Bass seems to go a little deeper than standard DT770.
• Heard some drums that sounded absolutely great with these. Big and powerful.
• Technically better than standard dt770.
• Better/wider sound stage.
• More resolution.

Today during work I had them connected directly to my TV so they get some time. Sounded fine, but it was during work.

It shows that the stellar.45 driver is a step up from the older DT driver. The small upgrades (detacheable cable, less clamp than the pro headset and the indented headpiece) make it a step from the older DT 770. If I have the time in the next weeks I'll check against the DT770/80 and DT700 Pro X that I have and do a quick sweep to get the FR using minidsp HEARS.

It seems they are perfect for me and the purpose I intend to use them for, I was planning to use them together with my iMac24 for youtube and movies, and also together with my Mackbook laptop outdoors, and extended highs are not a problem for me anymore as I am 67 years old, quite the opposite actually.

I signed up for the preorder notification but, in a rare moment of self control, I didn’t buy them when they became available. Am I a new man or will I impulsively buy them later? Who knows…

That's good to hear, based on my listening the Stellar.45 drivers seem like an upgrade from the rapid reflex drivers. I personally decided against the DT 770 Pro X for now (may grab one eventually) and just decided to get the DT 900 Pro X in addition to my DT 700 Pro X as I managed to address the headband comfort with extra wear, I prefer the pads on the DT 700 and 900 Pro X, and I prefer the more relaxed treble on the modern Beyer tunings.

I got a pair the other day and posted a review here at:
https://www.head-fi.org/showcase/be...-x-limited-edition.27016/reviews#review-33615

I was really impressed gaming with it, but needs some EQ to really shine with music. I think it'll have more potential when some official measurements are done to dial them in more accurately. Glad they kept the pad and cables standard with the other models.

DT 700/900 are a pain when I stared but now I don't feel them at all. I hang them on a narrow headphone hanger which eventually created a dent such as is present on the dt 770 pro x as well. Works wonders for me cause now I can enjoy the DT 700 and 900 for what they are: great value for money headphones.

Yeah, I don't really notice them either and are becoming some of my most comfortable headphones. Yeah I am using a narrow headphone stand to put a dent into the headband padding as well. It's hard to say whether I like the DT 700 or DT 900 Pro X more. I felt the same about the T1.3 and T5.3, was hard to say which I liked more sonically. Beyer definitely knows how to make closed-backs imho, they're also one of the few brands that does cloth pads on many of their closed-backs. Curious about your long term impressions of the DT 770 Pro X compared to it's siblings.

Whats the differences (tone balance, frequency response) between DT770 Pro X Anniversary (closed) and the open DT1990 Pro or Amiron Home?
The drivers of DT1990 and Amiron are "Teslas" - what is used in DT7xx and DT9xx series?
Are stellar.45 driver “Teslas“?

I don’t think so, otherwise they would have called them that.
Beyer seems quite proud of those new drivers, they explained the construction in detail on the pages of the DT700

Edit: I did not find the article I remembered, but there is a video about that new driver available (German):

The high efficiency of the STELLAR.45 transducer is also achieved through use of a top-class N52 neodymium‑iron‑boron (NdFeB) magnet. Thanks to the tiny magnetic gap size and high quality of the magnet, a field strength greater than one Tesla is created within the gap.

No, Tesla drivers are in Beyers upper level headphones.

Decided to order the DT 770 Pro X LE, from Amazon but it’s from an authorized retailer this time so I should get the actual headphone I ordered this time. I may return the DT 700 Pro X depending on how I feel about the DT 770 Pro X considering the DT 770 Pro X is what I was supposed to get.

The DT 770 Pro X does have a tweaked Stellar.45 driver as it has different rear venting and baffle venting than the DT 700/900 Pro X driver (same driver in both the closed and open version).

I mean more than one Tesla magnetic flux density
