A Closed HD600 Headphone! Sennheiser HD620S Review

[@sennheiser]

Hi👋Thank you so much for the review and awesome footage! We wanted to offer the viewers some notes from mothership. The HD 5-- chassis is terrific for A) the transducer geometry B) long term comfort C) producing a closed back at scale where leakage variances cannot be tolerated. The HD 6-- series is open and hand-assembled, so variances in the baffle assembly, etc are negligible. Neither the 5-- nor the 6-- are good candidates to fold up, however. We indeed increased the depth of the ear cavity vs the old 5-- series by about 5mm, based on user feedback. For tuning, we wanted to straddle clarity and balance with fun so that you get vibe without straying too far from the original recording. With regard to soundstage, we'll respectfully debate you on that and designed it to be a panoramic experience, especially compared to the the closed-back category--ultimately we hope anyone reading and watching gets a chance to try them with a favorite source and set of test tracks🎧 Great work and we welcome the feedback (pun intended)💙 Edit: HD 620S is wired for balanced and a 4.4mm cable is coming mid-summer 2024

I clicked on this video so fast, I’ve been waiting for this for forever(2 years since I got into the hobby).

[@GenoMusic]

Awesome video as usual! Quick question to you and any other experts, do headphone extension "clicks" on the headband have to match for the left and right side? Does this affect sound quality? Or should I just look for the most comfortable fit?

[@sennheiser]

There are no detents, and they can be adjusted asymmetrically---most of us do not have ears in the exact same "latitude", so you would just adjust them to where they are most comfortable. They have a wide sweet spot, so its pretty easy to find.. We chatted about this in another video comment but thought the other readers might find the answer of value.

[@64-bitMicro]

It's like they took the 560s, which actually sounds great, and replaced the grills with blanking plates. Although it does look like the resistance values are different.

[@sennheiser]

Different driver, different baffle, different driver surround, radically different driver tuning (closed vs open), different front and back volume treatment/tuning, different headband, different earpads, diff...see more

[@TECHNICKER_Cz]

how would these compare to the K-371?

[@chikemadekwe5737]

I've been making music for over forty years now. In my opinion, the only way to decide on the sound you require is to personally try them out as we all have our own level of frequency reception due to a myriad of things. My research via spec, lead me to Sony, but when I personally tried them both, I bought HD650's. I'd arrived in heaven. 😊

[@ramihaidafy]

I wish you talked more about the physical build, like what comes in the box in terms of cables or accessories, are the ear cups replaceable, and if so how do they connect? Via clips? Are they magnetic? etc.

[@bornaetemadi]

can you make a comparison between these and the DT700 Pro X and the DT 770 Pro X ?

[@NyteStalker89]

Do you like stabby treble? If yes, get beyerdynamic. Does stabby treble hurt your ears? If yes, get hd620s. Imaging and sound is more pleasing to MY ears with each hd620s.

@@kituruken7947 Tuning is a mess. Detail is not really there for the price. Build quality is the only thing going for it, but the original 770 and 700 have that as well, so there is no reason to pick the 770 Pro X over either of the two. The 700 Pro X is better tuned and the original 770 Pro is more detailed and features a simpler build.

[@techkernels]

IMO, the headband and the design doesn't look like it's a part of the Sennheiser 600 series, not sure if the HD620's name should be slapped on there

[@sennheiser]

We left a reply that talks about this but will summarize here: the driver is all 600 DNA but to get a closed back to sound good and manufacture it at scale you cannot take the same approach as the hand-built HD 6-- chassis. Either way we hope you get to try the new HD 620S to judge for yourself 🎧

[@vvraithz]

i wish Senn come out with a HD 900 or something that goes further than the HD820s. They need to compete with the £2000-£3000 market.

[@Tssukiii]

What made me decide I like them was a 5min listening test right after hearing the He-1 And they still sounded good which impressed me a lot I also heard the Maxwell at Munich which I didn't like at all, even worse than some IEMs at 60 bucks Maybe something bad with my connection, idk, but the HD620S, Meze Alba and Warwick Bravura were my absolute Highlights

[@sennheiser]

Thank you for coming by and trying them both out. HE 1 is tough to follow and we still wish you did it in the opposite order haha

[@xyliss]

Lets not forget about one of the most significant differences between the 500 an 600 lines. The 500 line is running low on model numbers.

[@sennheiser]

Big headphone doesn't want you to know his 1 trick

[@ninja_boy]

I tried this headphone and I also found it was not for me. I was impressed with the isolation and with the fact that the bass and highs were not exaggerated, and it sounded quite nice with my electronic music. Unfortunately I found the timbre to be off and it just didn’t do classical/orchestral music justice. (This was listening with iFi Go Bar Kensei).

[@audioreviews]

The best review is all reviews...to get a complete picture. I recommend reading (yes READING) some of them.

[@argo117007]

How is this vs the 560s which it resembles?

[@prasvt]

Outside of the Audeze, what other closed set would you suggest? I have the HD600, HD660S2, and the Ultrasone Edition 11. The Ultrasone to me probably has the best bass of an open back I've heard, while just being good at everything. Just trying to figure out where these would fit in my collection.

[@sheep7255]

[@minatoaqutansaiko]

Hello, I just want to use one earphone and don't want to be tired of switching devices all the time depending on the type of music. I listen to 80% classical and 20% jazz and pop. I I think I like mm500 very much, and I think the instrument part is quite good, and the vocals are in the front, so the female voice sounds good. Do you recommend other headphones at this level? I think the Sound Stage of the mm500 is ok. For classical music, the instrument is not too modified and artificial, the low-frequency dive is enough for jazz. I'm still looking for a sound I like, maybe you can give me some advice or other information.

[@nefasto8730]

Thank you for this video, it was very helpful. I need headphones that can totally isolate me from noise and the voices of people around me, would you recommend the best headphones with noise reduction? It would definitely be handy to have a microphone with the same noise reduction and maybe wireless, because I use them exclusively for gaming. Thank you very much!

[@PhoggHawk]

Others have described these as "boxy" sometimes as well. What is a good way to describe what that sounds like? I am not sure I understand.

[@Marian1st.]

Which sounds better, HD25 or HD620?

[@AquarianDiary]

Curious if an iPhone with the Apple 3.5mm dongle can drive the HD620S. That setup is just slightly, and unfortunately, insufficient to drive the HD600's in my opinion. I use my HD600's mostly with an RME audio interface but sometimes it'd be convenient to use them on the go for more casual listening without other extraneous third-party hardware.

[@imabeliever85]

I wish they still made the HD 239, that sounded kinda like the 600

[@MatthewDiFazio]

Hey! I’m actually posting a review today, but I do mention that I used the Apple Dongle to drive it and reached comfortable listening volumes. They’re very efficient and portable :-) hope this helps!

[@AquarianDiary]

@@MatthewDiFazio Thank you! I'll look for that.

[@DeatheCore]

Always wanted a HD6x line closed back, so thank you Sennheiser for your efforts on this one, however... Guessing it uses the same super-microphonic cable as the rest of the HD5xx line - is it not possible to make a cable using the same materials as the HD6x cables? Also this chassis is notoriously quite creaky and plasticky, which is okay if you never move your head at all... I think this would have been a no-brainer if the price was $200 - $250 as Joshua mentioned. Unfortunately there is no place in my country to test these so I need to rely on reviews and comparisons to make sense of the pros and cons.

[@josh_wink]

I wonder how the tones would change with some pad rolling. Could the right pad get closer to the 600 series timbre

[@sennheiser]

Wouldn't recommend it, not velour pads anyways. You need the seal for the bass response.

[@jamesmiller4487]

Thank you for your honest opinion. I have the Maxwell, the Aeon Noire, and Bokeh. I think I can pass on this one.

[@Burn_In_Oled_On_Purpose]

The 620s looks like a closed back version of the open back version of the 520s with a different number and line from sennheiser line of headphones. I wonder if any of the current sennheiser engineers would consider engineering the close back marble version of the open back version of the sennheiser hd 600. I have the marble version of the sennheiser hd 600 and I have been looking for the same sound signature, same tuning, same frequency response, same drivers as the sennheiser hd 600 but in a close back version, even the same 300 ohm impedance. Basically clone the original marble version of the hd 600 or even the redesigned version of the current hd 600 but have it close back instead of open back with the same exact specs and features. I have the neumann ndh20 close back headphones. I don't know how many hours of burn in I did with my neumann headphones because I did not keep track of it. When I first bought them, the bass was not as warm until I burned them in but the bass response is leaning towards the warmth side because the engineers for neumann design the headphones to be similar to the hd 650 or the hd 6XX.

[@jamesbittle9789]

It has excellent soundstage.

[@ik1llpeeple4fun]

It's because everyone has different ears lol. And possibly because while it may sound airy and have great imaging for positional audio - it may still not sound as wide as some people desire. Not saying it's narrow etc, but no closed back can sound as wide as an open back. I just ordered these for gaming, but i prioritize imaging with a preference for an airy sound over having the biggest /widest soundstage. I don't need to sound like I'm in an empty stadium the size of a football field for games lol. But spatial /positional audio details for a good closed back is what's rare imo. Even if the details are in a slightly smaller 'size' than open backs. Can't wait to try my pair when delivered lol.

[@mattrismatt]

Comparing each in stock form, I have no doubt that the HD620S would sound much better. Having said that, I'm confident the Focal Elegia would win with (real) leather earpads installed, unleashing the potential of its metal-diaphragm driver, especially regarding dynamics and bass solidity. The difference with leather pads over stock pads is night and day.

From the same price range I've got the Austrian Audio HI-X60 and as controversial as this may be I love it. It is well extended in the sub bass, a bit colder in the lower mid range, it has a bit of an hifiman dip in the 1.5kHz/2kHz to 3kHz and it is slightly emphasised over 4kHz. I think it sounds really amazing especially for a closed back at this price. I wonder if anyone has actually compared the two because I wonder if the HD620S is any better or even as good as the HI-X60. Anyway I strongly recommend the Austrian Audio HI-X60.

[@DominikHolenstein]

I tested the HD 620S last Saturday and I am not impressed at all. Sennheiser sells them as "closed back headphones sounding like open back ones" what is simply not true. The HD 620S is too expensive with USD 350 and I agree with you that it is in the USD 200-250 range. I must admit that I am very biased to open back headphones.

[@Jason75913]

Those HD620S headphone drivers so look like just another HD595 on Senn's site. Those closed-back HD5xx chassis are junk, and Sennheiser doesn't try and attenuate the resonances inside of the cups, though they perplexingly did for the old HD360pro portable headphone. Pioneer's HRM7 gets fiberglass dampening inside, DT770 gets that thick white wool ring behind each driver, the classic DT660 gets a bunch of wool so you don't hear the cup resonances, and audiophiles from its time all recommended it as the only closed back worthy of classical music because of its good tuning and very balanced tonality. DT880pro has a bunch of wool inside to help it not sound cavernous like closed Senns and most closed Audio-technicas tend to. Sennheiser is oddly lazy. If you are unsure of bass interfering with the mids, use an equalizer to attenuate midbass 6dB or something to find out, simple as that. Bass definitely steps all over the midrange in HD25, lol!

Nice review! I have kinda have the impression that Sennheiser didn't like the feedback they got for the 660s2... The sound quality got overshadowed by the bang for the buck aspect that didn't seem to be there, So... They thought "Hey, let's design and produce drivers in Ireland, so the sound will be great, and let's assemble it in China to keep cost low. Oh, we could even use the exact same assembly line than the 500 series models..." I still think this should have been a 500 series flagship. But hey, would have less marketing impact than calling a 500 series 620s I guess haha
