Sennheiser HD 620S headphone Review - Surprise Hit?

The new Sennheiser HD 620S is a closed back headphone, intending to be similar in tonality to the legendary HD 600 and HD 650 headphones loved by many. As a closed back headphone, there are tradeoffs to be expected, but there are also reasons why some people need a closed back headphone. In my review, I discuss everything from comfort to sound quality, including performance in gaming and how it compares to other models.

[@sennheiser]

Thanks so much for giving these a try, Joe! We don't mind a long review at all and appreciate your in-depth feedback. Glad to hear you are enjoying them!

[@DirtyMuzzie]

Give the man a sponsor

[@VeeHausen]

I would love for Sennheiser to start dabbling in Planar Magnetic Drivers man.

[@ursdubel3585]

Watch out for Sony

[@rene837]

Nah, let others deal with those. We need dynamic drivers for the timbre that the 600 lineup is known for.

[@NyteStalker89]

Yeah, no.

[@burns0100]

This is the best review of the Sennheiser HD620S I have seen. Talked about the graph, compared them other other closed backs, talk about the clamp force and how these relate to the rest of the Sennheiser family. Honestly you covered it all and in a very straight forward and honest manner. I've gone down a rabbit hole on these and plan to buy them when I can but as far as what everyone else is saying I can agree, these seem to be one of the better closed back headphones to date. Sennheiser put in the work and got something actually usable. Closed back headphones aren't easy, there is a reason you struggle to find a good pair outside of the Sony, Bose, Beats and Apple wireless headphones. Glad Sennheiser pulled it off in a way.

[@Lost1ntheSauc3]

Best review so far! You described them almost exactly how I would. I've been loving them.

[@GadgetryTech]

Awesome! They are a pretty awesome headphone. I’m glad you agree with what I said!

Excellent and detailed review. It seems to be an interesting set of cans. I might grab them when they (eventually) go on sale.

[@GadgetryTech]

Thanks!

[@ChaoticKyle..]

Love this review

[@reluctant_engineer]

Nice review as always. Would've loved to have it compared to AKG K371/K361 tho.

[@nathangothan601]

Have you done a video on your EQ recommendations for Rainbow 6 Siege? I’d love to see one, if not. Been using the HD560s and these are interesting to me for games where footsteps are so important.

[@bubbasheik]

How would you compare these to something like the Turtle Beach Stealth Pro for imaging and soundstage and other headphones currently on the market? I am trying to figure out what would work best for pinpointing footsteps and where my opponents are

[@criptocolorlightstech5292]

Joe what’s up I just got the hifi organic today what cable did u swap out the stock cable for and did it make a difference in the sound quality

[@eilon89]

Thank you for the review..I just got the maxwells and while i love very much the sound of them its hard for me to use them because the vaccum effect they creating..how are these compare to them in terms of bass? i really like the bass on the maxwells

[@Benzo97]

I don't usually do requests/suggestions, but given the fact that you're one of the only reviewer for anything sound related that I find very useful and trustworthy, I'm actually curious if you'd give the Sony Bravia Theatre U neckband thing a test, especially since that there aren't much coverage on those.

[@memorycard1000]

Isn't that bump at 110 hz made so it would fit gaming? I can't recall, but I think I read these focused on gaming? Anyways. If you eq the 110down a tad do they get that deep subbase? Great channel this is. ✨

[@kobbyampofo]

How do these compare to the DCA Aeon Closed X?

[@AzraelMorrison]

Fantastic review and very informative. Looking forward to your more detailed opinion of the Rode headphones; they seem more my budget. Question: what are those headphone stands you use? I am looking for storage options and those look neat

[@GadgetryTech]

Thanks! I’ll try my best to release that video when I can. The stands at form ROOMs audio. They are rather expensive but i wanted heavy stands that would last forever. www.thomannmusic.com/rooms_audio_line_typ_fs_pro_bk_headphone_stand.htm

[@Carlito.undercover]

Can we get a bit more in regards to comparing this to the Maxwells? Which sounds better, bass and overall fidelity? Is comfort that different on longer periods because we are comparing a suspension strap with really good spreading of the weight to a fixed cusion headband. Thank you, love your reviews.

[@LuciferArc1]

Would love to see you review the ath-msr7b (second gen msr7). Personal favorite closed back

[@DarthRaven2]

If you were to eq the Rode NTH-100m how does it end up comparing afterwards with the 620s technicality wise ? Also i feel like havin the regular DT770 Pro 80 ohm would be better since thats the one most people have(one of the most popular ones still)

[@Medsas]

can you compare to dca aeon closed x? thanks

[@Xsetsu]

I wonder if they might be alright for mixing. I really miss the Sennheiser's HD8, which I was in love with. I was wondering if they were anything like those considering they are closed but with a little less oomph in the kick drum region. DT770 have always been a bit much in the highs for me. Also wondering how durable do these feel.

[@Hijynx87]

I've always wanted to try those Rode headphones, thanks for reminding me of them, that graph looks nice. I just got the Aune ar5000, do you plan on reviewing those?

[@GadgetryTech]

Thanks! So I’ve been getting asked a lot about the Aune headphone. I’ve written to the company but still haven’t heard back from them. I worry the video won’t be popular enough to justify the investment but I’m debating on it

[@user-ot6ti9mu3i]

Sorry for the intrusion..yep the Aune ar5000 are premium sounding headphones on every level.

[@Hijynx87]

@@user-ot6ti9mu3i they are a good balanced sounding headphone. Like the hd600 with bass basically. Also better imaging and soundstage with vocals front and center, so it should be great for gaming.

[@limb_be]

Looking for a good New headset to use on call of Duty - Warzone , I was thinking of the 560s but I'm not sure, are there any other good options ???

[@Andersg85]

Which dac/amp would you use for gaming with these cans

[@TarixVR]

I love my 560S, but have been wanting something better for sound isolation when family invades my gaming space 😊. I’ve considered the maxwells, but last time I tried them, I couldn’t tile the discomfort they caused. Wouldn’t 620S be a worthy “upgrade” from the 560S, while also providing enough passive noise cancellation to drown out a TV blaring in the background?

[@jorgeluisfernandez2560]

Hd 660 s2 is a better choice? I know is an open headphone but i want to kno which one gives you best sound quality...thanks

[@rkrnddl5]

For cod, pubg, r6 competitive play. Which one do you recommand between this one or hd490pro? My pc is quiet noctua fan pc so i can use open 490pro with no issue, but only my concern is when i use some openback(like dt1990) sometimes my mic captures my headphone audio via discord... so i cant decide 620s or 490pro well.. can you help me?

[@ColinAlexander-sx5yk]

I want a good closed back for story games.gsp 602 or hd6 pro witch of the two is better. I want deep bass without muddying the other frequencys .

[@jeanbenoit6610]

great review! would you say, the bass of the 620s comes close to the bass of the DT 770 Pro X LE out of the box? im not a bass head but i remember the bass on the HD650 being really weak...

[@user-ot6ti9mu3i]

I have both .. straight out of the box. Music wize the DT 770 pro X winswith its beautiful non bloated bass. 620s has a tight linear bass but lacks impact. But hey what do I know 😊

No. K371 frequency wise is better

[@Hijynx87]

thats semi open

[@Wulfrig1911]

I want these so bad for music production!

[@voldy3565]

So how much noise from the outside can you hear with these on? How much sound do they leak out?

[@GadgetryTech]

They block a decent amount, better than many of the other models mentioned here. Nothing is sound proof though

[@voldy3565]

@@GadgetryTech Do I need amps and additional equipment to make these sound good, or do they sound good by themselves? Will I be able to use this with small devices, like an iPod nano?

[@clairvoyance7424]

560s and 620s earpad interchangeble?

[@iFort]

Yes, but not advisable. The 620s got faux leather with perforations for both venting and acoustics -> putting other 5xx series earpads will impact the sound, isolation and comfort.

[@user-ot6ti9mu3i]

Am I missing something? No disrespect but the 620s are a no go especially compared to the Dt 770 Pro X LE where straight of the box become alive. Brilliant tuning to say the least. The 620s imo just didn't excite but then again I don't have any of the upgrading tuning devices either. Excellent review. I can't wait for your review of The Dt 770 Pro X LE in which I know I hope everyone will enjoy as much as I. Shh the secret is out...Aune-AR5000 is another to also consider.

[@burns0100]

See I think I'm the opposite. I don't like the DT770 Pro X, they sound too thin, shouty for me. Mostly because when compared directly to the 620S they have less mid bass and more treble. 620S have less sub base and less treble but a much better mid range. So they really are for two different types of people. You will either like one or the other not both. Also for the price difference I think Sennheiser have better build quality. (Just an opinion).

[@user-ot6ti9mu3i]

@@burns0100 it is amazing how two people have a difference in hearing and interpreting sounds. Aside the Senns having a pronounce midrange they simply lack sparkle transparency air if you will.. How you describe the DT 770 pro X is exactly how I hear the 620's. No umph no dynamics sounding just like another Philips HD..very cardboard sounding. In my opinion.. the Beyerdynamics are epic in comparison. .dynamic soundstage that punchy bass airy instrument separation midrange sparkly highs without fatigue. Lol I guess I love my Dt 770 pro X which is funny because I have never enjoyed a Beyerdynamic until now. Thank you.

[@burns0100]

@@user-ot6ti9mu3i It's very much a case of two similar headphones with different tuning takes (basically focusing on different aspects of the frequency response) and then how our ears reproduce that sound. That's why audio is so subjective. Even when he mentioned using different measuring rigs is like another pair of ears. It's so true.

[@5_i_v_e]

The measurements looks like I'll be great for COD lol. I wonder how it would do for XDEFIANT.

Seeing the HE-R9 on someone from that perspecive always cracks me up, they really do look like someone wearing lipstick on the sides of their head.

DO NOT EQ BASS UP UNLESS YOU WANT TO LOOSE YOUR HEARING. Harmon 2018 bass levels should be Maximum.

For good reason, may they remain forgotten about.

[@damiendubocage6312]

if clamp force is better than 560s il will buy it for sure !!!!

[@GadgetryTech]

It's slightly lighter but the more plush pads make a huge difference

Clamp force and earcup depth are both better so they just feel better on the head.

I heard closed is better for SQ more accurate! I don't know how true that is. Could be another benefit for closed headphones.

[@Hijynx87]

definitely not, most closed backs have some wonk to em.

[@GadgetryTech]

Closed backs have the benefit of sound isolation, and sometimes more bass impact depending on the model. For more accurate sound reproduction, open acoustic all the way! At least in the headphone space.
