So far, I agree with what you have said. Detail and spaciousness seem better than my HD600...something I did not expect. The much betterPurchased these after auditioning at my local shop—though I likely would have purchased sight unseen given my preference for Sennheiser’s 600 series (I have owned 580, 600, and 650. I’ve also owned Beyer DT1350, Meze 99, Hifiman HD400 and and some others over the years). I was in the market for a closed back headphone for listening to music in bed, and the 620s appeared to check the boxes on paper.
To my ears, the 620s are exceptional. Having tried many models, but invariably selling them and coming back to SENNHEISER 600 series, I can say that I’ve never experienced such satisfying, yet accurate, bass out-of-the-box in any set of headphones I’ve tried. I always eq my 650’s using Roon or my RME ADI-2 DAC to get accurate bass extension. but even with that, these 620s provide more of the impact and detail that I crave and that make music exciting for me than the 650s. That’s Probably a result of the closed design. I’ve barely done any eqing. While i’ll be interested to experiment, I don’t feel much need for it yet. There’s a lot of detail in the treble and it does, indeed, sound more “open baffle” to my ears. Isolation from outside noise is also a welcome improvement from my open back 650s and adds to the perceptions of detail, I think. I no longer get requests to turn down the volume from my wife next to me in bed…
So, in service, as well as on paper, these check all the boxes for me. I’ll be interested to hear other folks’ opinions.
First...thanks for your review. I risked it and bought mine blind and love them more and more as I use them.Azurys are twice the price of the HD620S
In order to decide which to buy I suggest to listen to both of them.
When that is no option wait with the buy until there are more than enough opinions on them and reviews of both headphones.
Thanks for your superb evaluation of the HD 620S: Sennheiser HD 620S reviewAnd yes, these headphones are very good.
Quite mediocre. A verdict < 7 is quite rare on Rtings.FWIW...
Sennheiser HD 620S Review
The Sennheiser HD 620S are higher-tier closed-back headphones that the manufacturer promises can supply a wide and immersive soundstage like open-back headphones...www.rtings.com
I don't put much stock in their numerical ratings as they include a bunch of factors that are almost always irrelevant for me.Quite mediocre. A verdict < 7 is quite rare on Rtings.

After I finished reading the RTINGS review of the Sennheiser HD 620S, I couldn't help but feel that it wasn't offering much value in its price range. Sennheiser has introduced relatively few closed-back models and (at least by RTINGS measurements) they don't seem to score as well as their open-back headphones. Personally speaking, I'd want to compare them to other models with my own ears before making a purchase. Closed-back headphones aren't a necessity in my situation, so for $350 there would be quite a variety of other options to choose from (including open-back models made by Sennheiser).I don't put much stock in their numerical ratings as they include a bunch of factors that are almost always irrelevant for me.
But some of their specific remarks are rather disappointing, and they have a handy graph tool:
I'd still like to hear them, but I don't think I'd enjoy them.
Among the Sennheiser closed-back headphones tested by RTINGS, the HD 280 Pro and HD 598Cs scored somewhat better. Both those models showed good compliance with Harman in the bass and midrange, but their treble accuracy fell below the curve (while the new HD 620S showed inaccuracy in treble and bass ). As is not uncommon for closed-back designs, all 3 models scored well in imaging but poorly in soundstage. Distortion values are average. If I needed to choose between these models I'd be interested in comparing my subjective impressions of the HD 280 Pro with the HD 620S (and I'll admit that my frugality would probably incline me to prefer the $90 HD 280 - which I'd like to improve with a little equalization...) Still, I'm glad for those who love the HD 620S.Sennheiser wasn't very lucky when it comes to sealed headphones, maybe except the classic workhorse HD 25. The HD 569 wasn't that great either, albeit very comfy.
The HD280 Pro has great isolation. It's actually good enough for use on airliners. Unfortunately, it's not very durable. They are widely available without having to wait for mail order. I bought the last pair at Guitar Center.Among the Sennheiser closed-back headphones tested by RTINGS, the HD 280 Pro 2016 and HD 598Cs scored somewhat better.

HD280 has a rather colored sound. I like other closed backs I owned and borrowed more, SRH440 non-A, K371, DT250-250Ohm, DT770-80, even MDR7506.Among the Sennheiser closed-back headphones tested by RTINGS, the HD 280 Pro 2016 and HD 598Cs scored somewhat better.
