yes,top of them price=quality

[@kanou654]

The frequency response graph is the measurement result in my recording system, I think I’d show it although it’s not exactly the same as what we hear with our ears. But by comparing other Demos on this channel, we can still find some RELATIVE differences. I will also continue to improve my recording methods. Hope you enjoy these Demos.

Dude. Im only on second minute, and i must say it's best demo on these headphones i've heard. It actually translates how different they are at soundstage. Nice stuff.

I'm listening to this through my Sennheiser HD560s. To me the HD800s sounds the nicest. It brings out some high-end detail without sounding very colored like the HE1000 v2 which has some extreme peaks and dips in the frequency curve.

[@fagiolo2376]

Me too 560s. Thought HE1000 sounded way better than the 800s though, lot more clarity withought being agresively bright. For Classic and rock (#3) i did found 800s better than all 6´s and the while those were better in #1 and #2.

[@jstevo1349]

the hd800s sound really nice on the he1000 v2 too

[@MacXpert74]

@@jstevo1349That's interesting. Too me the HE1000 V2 has some weird peaks and dips that sound unnatural in this demo. For instance at 11:59 when they switch from the HD660S2 to the HE1000 V2 the cymbals sound ear piercing to me, very unpleasant. But maybe it's because of how it's recorded, I haven't heard this headphone in the real world myself. The HD560s I'm using is pretty flat and neutral sounding though.

[@jstevo1349]

@@MacXpert74 i have found that when i first got them they were peaky and but it was consistent across the treble. however i was coming from focal clears which are a little duller to begin with and over time ive come to appreciate the detail and clarity these bring more

[@citizenx1602]

Technically speaking for me HD600 and HD800S sound better on a warmer system (iFi Pro iCAN Signature as amp, first Tube mode, 10Hz XBass level) and HD650, 660S, 660S2 on a neutral one (Violectric v550 Pro) no matter what DAC I use. I also have HD490 Pro (plus version, just bought) and HD560S. However, I can't say which of them I like the most, each of them has their own charm, character and music representation.

[@SC-or2zb]

amazing video

[@jorgeju115]

HD 600 and Fiio R9, a pretty heavenly combination, an intimate but wonderful sound full of details and dynamics. I have heard a lot of people complain about the bass of the HD600 because for me they are perfect, the bass is natural, at least in my case, the source is very important to get the most out of these headphones.

[@moskva-kassiopeya]

This is an amazing comparison, thank you! It could be even better if you add original tracks somewhere in between the headphones recordings. Anyway it's great and gives a good representation how these headphones are differ from each other 👍🏻

[@kanou654]

Thank you! All the tracks are based on my recording environment rather than real human ears, so I can't 100% guarantee that the one that is close to the original tracks will also be close to the original tracks when listening with our ears. I'm a little worried that it might mislead the audience, so I did not add original tracks😅

Another thing worth mentioning is that the 600 headphones never becomes annoying, even at high volumes, because it has a veiled sound. It's as if everything is EQ'd below zero. In contrast, the 660S (and 660S2) can become fatiguing after long listening sessions because they bring too many frequencies forward.

[@larrydunn4626]

very interesting. There is a lot of information, such as triangle strikes, revealed in the 6k and 8k peaks of the 800s that are almost non existent in the other three earphones. something is not right with the S2s replay of vocals... too recessed for my taste... but its bass is great.

The 660S2 "looks" like de frequency response of the new 490PRO.

[@donvittoriosierra]

Based on this sound demo, s2 is the most natural sounding

[@crimson_floyd]

Basically if you want a more intimate vocal performance then get the 650 or 600. If you want a wider soundstage where the vocal is less intimate then get the 660s2. I personally don’t like my artists singing to me as if they were right beside me. I’d choose the 660s2. But of course, the 800’s are best overall.

[@RajaaDima]

650 >600>660>800 for me (the HE sounds very different so I won't include it in this comparison)

[@Miguel-mr7wk]

The hifiman is terribly sharp, I was curious about the planar but that totally discouraged comparison, they are very bright.

[@loki76]

HD800S is the best one. Nicest clarity and range. The HD600 follows because it also have the nice clarity and all around sound. The HD660S2 after that. It has the most sub-bass which is nice. But don't know if I can say it beats the HD600 because of it. Because if you EQ the sub-bass a little on the HD600 I am sure you can at least reach the default state of 660S2. Given the prices of all of them The HD600 is the winner. The HD800S is heading towards "end game". The actual reality though is they all sound like Sennheiser and differ very little. Closing my eyes and I couldn't really even tell when it switched to the other headphones. Ironically I am listening with Senn 560s. I own so many Sennheiser headphones. This time I went for Sony MDR-MV1 to try and have a different sound signature. Can't just buy more of the "same' all the time. MV1 has a lot more bass than any of these despite also being open back. They are made for studio mixing of spatial audio. So they supposed to be great for Atmos, 360 and virtual surround pin pointing and so on. I guess I will find out when I test them out. The MDR-MV1 is in the higher end so basically more than HD600 in pricing. Doesn't mean they are better. Just that they are not some kind of cheap afterthought headphones. Here's hoping they knocked it out of the park for movie and gaming. I am not an "audiophile MUSIC" listener. I don't care about that. I care only about 7.1, Atmos, 360 and spatial audio for movies and gaming and even in music.

[@mikafoxx2717]

560s, is probably the best for games. clearer top end, lower subbass, comfort and better soundstage than the 600. 490 pro is more or less a fancier 560s that's meant to replace the 600 in some ways.

[@mikafoxx2717]

My thoughts: 660s2 has better bass extension and more.. modern sound? But compared to the 600 feels less natural. 800s is a bit bright but mostly sharp cymbal type sounds. 650 is just the 600 but smoothed over and made more mellow. HE1000.. is.. awful on this recording, hopefully it doesn't sound like that. No air except a huge 10k peak. My Sundara is nothing like that thankfully. Listened on HD600.

I have Sennheiser HD650 and Sennheiser HD800. To be honest with you most of these headphones from youtube videos when comparing Sennheiser lines sound pretty the same to my ears. You have to put these headphones into the real audio chain with great to expensive gears to really hear the real differences between them with your own ears, do not judge these headphones seriously from youtube audio videos like this, audio videos make HD800s inferiors to other HD6xx lines, no. Even at my home I can hear Sennheiser HD650 and HD800 have similar sound signature but there are a few differences like HD650 sounds like in your hear or near your head and HD800 still carries a lot of HD650 sound but with a huge distance, more details, clarity, better bass control on higher resolution and speed. Sennheiser engineers really tune their reference headphones alike each other, like 70-80% but with up or down db different. To my preference, HD800/HD800s are clearly superior to other Sennheiser headphone. The HD600-650 win just only about their slow timbre and bigger midrange sound than HD800/800s, these make them sounds like more romantic, smoother than HD800 but not as real as HD800. The rest HD800/800s win.
