5:50 for sound

As a note from a HD 650 user, I've had mine for 10 years and I bought them used. They will absolutely last you a lifetime.

Thanks a lot for your informed takes on these, Mark. Much appreciated.

i really like the clear explaination betwwen 150 and 300 ohm! i was so curious about what that was mean. Amazing video. Now i am clear about these S-HD headphones.I am going with HD660s now, placing order. Thank you Mr. Mark for your great video.

The way you explained open vs closed made so much sense, good work

Nice and concise presentation.. ty. If possible, unless you’ve done so, how about a short follow up review to this particular review. Glad I found your channel.

After getting quite frustrated because the L and R marking on the cans is not white but rather black - so hard to see in bad light, I am thrilled to find that there is a brail marking for the L side so now it's easy to 'see' in the dark!

I feel exactly the same with my HD 650 and 660S , For bad recodings i use mostly HD 650 this veil help a lot . But HD 660 are my way to go in anything else the most important was the speed , imaging and separation that i can Blind fold hear every time on these HD 660s.

Very nice comparison man👏👏👏👏👏👏

Thank yo my man.. Great comparison! I think I'll go for 660s also. cheers!

Nice job. Thanks for sharing.

Thanks. Great video

I have a lot of Headphones but i always go back to HD660s , the reason is that HD660s are not perfect on something like over 1.000 euro headphones are ...But they are good on everything . They have some warmth , they have clarity , they have smoothness, they are fast , they have separation,they have imaging, they are light , they are comfy , They are just 90% good on everything... For example Focal Clears or some planars are faster but lose on something else. None of them are good on everything.

150ohms doesn’t mean less requirement on power compared to the 300ohms. It is just that the 150ohms headphones will need more current and less voltage to sound good. While the 300ohms headphones will need less current and more voltage. Yes the sensitivity of headphone plays a important role as well

Nice review

thanks, enjoyed the review. I am currently choosing between the hd660s and Grado rs1e. I'm beginning to lean towards the hd660s...

Great help, thanks!

Really helpful comparison. I landed on your video for the exact purpose you made it. Thank you. How are the 660s working for you?

thats a kiwi accent alright , loved the review would love some more comparisons if you get hands on other studio classics like beyerdynamic dt880 pro , akg k702/712.

The... The temptation is so great. The urge to purchase has never been greater!

The 650’s are still my favorite open backs to mix music in. They translate to other sound sources extremely well. They’re honest cans.

Another great vid Mark! I think that extra 4.4mm Pentaconn male TRRRS connector cable you get with the HD660s is "optimally matched" to the Sennheiser HDV 820 headphone amplifier, not for an iPhone. PS - does this mean I can have the MH-40s you casually tossed out of shot? 😱

I ve used HD650 for years. They are practically indestructible in normal usage. They give a sense of presence on professional gear... but darkish;)

Thanks Mark!

Yes, I love my HD660S very much ....

A well driven HD6xx or 650 is amazing in its own way, almost a different flavor. Both are amazing but the WARMTH from the 6xx/650 is my personal preference.

Hi Mark, great interesting video, I recently got the 660 s for £259, as the s2 been out fir few months , I tend to use 660 straight onto the ifi zen dad v2 using the balanced 4.4mm pentergon lead with the true bass button selected and does come alive at the lowe frequency end. However if have the 6XX also but now fitted with custom cabs mod which also help with the lower bass end. I know that 6XX and 650 not quite the same but the custom cans mod can also be fitted to 650 too. Regards Mark

So that's all I needed to chose. I went for the 660s 🎧 👍

Thanks for the video! I have my HD650 for 6/7 years now, and they are just fantastic! paired them with an external Sound Blaster DAC/AMP, and does the trick pretty well. I will receive the 660s tomorrow, and curious what the difference is between my HD650 and if they are a keeper. Also received the beyerdynamic dt 1990 pro as a possible replacement for my HD650 after reading good reviews, but they were quite disappointing for me. First of all, wearing comfort is pretty bad. Maybe its because they are brand new, but I feel like they are really clamped on my head, and the HD650 is not noticeable at all. Swapping the earpads is a horrible job, and they just didnt sound right for me. Very 'sharp', and I am not talking about treble. Almost annoying at some tracks. But then strangely enough also sometimes very hollow and lacking in detail when gaming. So pretty much the opposite experience as what most users have. Seems that audio is subjective after all. :) Anyway, looking forward to tomorrow to see if the HD660s is a keeper instead of the HD650.

Good review brother. I need them for gaming, would HD660s do? If yes, do you recommend any small amp to use on the tv or on the controller (jack)? I wanted something plug-and-play but people say that these headphones only shine with an amp.

I have used a lot of headphones, and I can say that the 650's are the most comfy pair of headphones that I will never sell. Not the best headphone, but the most comfortable and not bad sounding. Nice on tubes. Get yourself a headphone amp and dac before reviewing headphones dude.

I’ve been looking for “daignostic” headphones so that I can accurately remove noises or artifacts during editing and shape the sound just right in as neutral a manner as possible. How someone subsequently listens to the finished result is ultimately up to their headphones or speakers and EQ adjustments. I don’t want my headphones to “improve” the sound in any way or hide the flaws. I bought the Byerdynamic DT 990 Pro, which completely missed nearly all of the subtle noises and artifacts in the raw recordings. I was shocked at how awful the final result was when I listened to it on ordinary consumer earpods. So now I’ve ordered the HD 650 headphones, which I believe let me hear the audio as it is. I even considered the much more expensive Neumanns, but looking at the frequency response profile, they also seemed to want to “improve” the sound in various ways. What I can’t understand it that if a manufacturer touts their product as “reference`’ or “editing” headphones, why doin;t they just do what it says on the tin?

i've been looking to upgrade from my gaming headset (corsair void elite) to a more "performance" headphone, and got stuck between (DENON AH-D5200) and (sennheiser HD600). i felt like the sennheiser was the better choice but i don't want to research and buy an amp/dac. this made me choose the HD660s. thanks a bunch

I haven’t heard the 650’s, but you are spot-on about the 660’s which has me in a tenzy because I feel that the 660’s are too separated in the soundstage, which takes away from the musicality of what I’m listening to...660’s would be excellent for music production work , but I don’t know if I could use the 660’s to listen to and enjoy music...The amount of separation of the instruments takes away from the cohesiveness of the overall soundstage of the instruments, which causes a distraction to the listening experience. IMHO....I just got them and going to give them a little more time, but I don’t know if I can get used to this.😂😂

I need a review of the HD660s with that new Audient id4 interface 🤔

I am comparing the 690 vs 650. The 650 I fee doesn’t naturally reproduce the intended soundstage and imaging rather it just imparts it’s own thing. Vocals on the 600 are more more balanced than on the 650. The 650 makes the forwards sound farther away, just about every song has the music louder than the vocals, which isn’t usually the right representation of the mix. Also the mid frequencies are a bit darker on the 650 and alter the tone of a song a bit. This is quickly noticeable on mid heavy genres like rock. The soundstage is wider but maybe a lil too wide in that it may make you think you are mixing things wider than what they will translate in other systems or conversely, make you feel something is mixed tight, yet it’s too tight on other systems and headphones without enough space . One quick example of the mids on the 650 is the end of dumpweed by blink 182 where there is a main guitar riff playing over or a side to a rhythm guitar with crunchy palm mutes. On the 650 the main riff is isolated too much and it sounds big and you can easily hear the reverb trails yet the palm muted guitar has less attack than it’s supposed to and is too recessed. On the 600 both guitars are more evenly balanced and the rhythm guitar has more presence because of its attack and crunch. You cannot hear the reverb as easily on the main riff not is it as isolated, but that’s how it sounds on just about everything and the song is glued together a bit more naturally. The 650 can make you feel more engulfed in the song but it adds a bit too much low end that alters tone, pushes the center a bit too far and does slightly off things with imaging . I haven’t heard the 660s but it seems they are even farther from the 600s so I feel probably even less flat and accurate in terms of frequencies and imaging. I’d like a slightly wider soundstage on the 600, but less wide than the 650. Just a tad wider . But overall the 600 simply does a better job all around I find. Any detail of individual tracks is easily focused on when working on that track, I can’t say the soundstage takes away from anything but in the 650 I’d say it’s not as accurate. Iv heard the 660 is even wider so I’d say even less accurate . I think the 6xx is less v shaped than the 660 , might be the next best thing to the 600 but as of now the 600 seem like a very solid choice

I'm pretty rough on headphones, but the only thing I've replaced on my 11 years old HD600's are the headband and earpads. Other phones I've owned hardly last a couple of years. BTW the 600 is a better reference phone than the 650!

Мастерит через карту ноутбука потому что ленивый? Хорошо что есть студия чтобы подправить. Иначе этот мастер бы на мастерил...🙃

Thanks for this the 660s direct to iPhone is they way I will go!

For mixing and coming from Sony 7506 which would you recommend that gets you closer to a mix that works on numerous devices? My fear is I’m going to hear a muffled sound on I coming from Sonys. Curious about Slate VSX

The extra cable on the 660 is a balanced pentacon, not an iphone jack by the way

Are the hd 660s the same as the 6xx?

nice. new channel to sub to. just didn't like how you throw away that poor old headphone of yours like it didn't serve you any good in its time

I can say this, if you ever hear a real headphone, this one is not touch ears anymore. Don't listen any reviewers how good or bad, listen it yourself, then listen airpods pro (or max), and decide give it 600$ or keep it.

What is the intro song? sounds nice

The hd 600 is dope

if i already own the 58x and 560s, are the 650's worth it in 2023 i wonder?

Aren't studio headphones better for mixing and producing? I thought these kind of headphones were more to "listen"...

you should try the HD560s bud

The high frequencies are of the charts in this video. I felt like I was using Beyer dynamics the whole time.

I am so sorry about this comment even before I post it. @10:52 I could NOT help myself thinking of Alan Partridge saying "Full Beam!" Maybe I am a bit stoned.

He didn't even connect them to a proper source 😂

This guy doesn't use a amp. He plugs them right into his laptop... 10:37

You sould have chosen the DT 1990 Pro. For mastering and mixing, hands down !!

You mean you're mastering on a laptop without a decent sound card? Oh my

Somewhat ironic that your audio is so bad on this video, I am listening on AKG K701 the Austrian made ones.What type of mic are you using?

You've been mixing on MH40s...before?? OUCH! Do they even count as pro headphones?

Am I the only Karen here to complain about the tossing of the Master & Dynamics??? 🤣

They don’t play sounds accurate, the bass is always too loud even with professional masters music and the hi end is really weird

Fix the audio and lighting in future videos

650 rules

650 is much much better than 660s
