I just got the 660s2, it sounds exactly as in the demo. Your videos are very accurate. I love the sound on these, I don't think the 600 and 650 can match the level of richness and detail you get on these. Best sennheisers till date
What music genres are you listening to with them? I am considering these but Sennheiser is well known for focussing on the midrange only which the frequency response graphs are proving and it shows me that they are having absolutely no sub-bass and are very flat and neutral which leads to a boring sound experience if you're listening to music genres like metal or rock.
@@makunouchiippo816 I know that the 660s2 are an improvement on the original 660s, but I can fix the lack of punch with my iFi Zen Dac V2 with True Bass on and some eq tweaks to clear them up a bit. And the 660s + ifi zen dac v2 did cost me around the 660s2 launch price, here in Europe.
@@makunouchiippo816 Im a big metal head. And I tend to agree with you regarding Sennheisers HD line. However, I have the 660s2, and I bought it because it suits metal and rock. It's abit more fun than the rest of the line. Don't get me wrong, it's not bass monsters, but they are never harsh, and the bass is there.

Good morning a big thank you for your titanic work it is easy for us to put a comment but to do your job, there are immediately a lot, but then a lot less people! This allowed me to choose my helmets and I come back to it again to discover the others THANKS
Amazing sound demo. Thanks for putting this up! I'm interested in the HD660S2 and looking forward to trying them first hand. I've previously owned the other headphones in the test. Subbed.
Listening through the H660s and B&O h6 2nd Gen, through iFi Zen Dac v2 ( balanced out on Senns ) I love the clearup of the sound that the HD 800 series bring, but I still love the warm nature of the 6, it's very easy to listen to for long working sessions and detailed enough so you not missing out much. And with a few EQ tweaks it can get a lot clearer + The Zen Dac has an awesome True Bass feature that brings the dryer headphones alive. I'm Ocassionally using the Boom 3D FIdelity mode software DSP for certain tracks ( mainly rock and live recordings ) does wonders. Overall I think that 660s strikes perfectly, it has good enough quality for most without that hefty pricetag of 800 series, and is not THAT far off in performance. BTW The 8:53 800s shows its real superiority in soundstage, imaging and precision over the 6 series.
Hi, interesting content , I also use my 660s primarily in zen v2 dac with true bass selected and Totally agree with you findings, I fitted my hd6 xx with custom cabs bass mid with improved bass at the lowe end , be interesting if any reviewer do a 6xx/ 650 with custom can mod against the 660s2 . Regards mark
Hi , great interesting video, I have a hd6xx with custom cans bass mod , does help bass at the lower end , I use my hd660s with my ifi zen v2 Dac with the true bass button selected and bass does alive and using the balanced 4.4mm lead comes with the 660s, regards mark
1°) Senneizer HD800S 2°) Sennerzer HD660S2 3°) Seneizer HD800 (Because lack of depth and precision in the low mids and bass) Now we should make a comparison between the HD 650, HD660S2 and the HD600
hd 600 looses too much in the low end for the 660s2 ? thanks in advance! such amazing video! if have 50 testing headphones I should be here til the end!
It's not the first time I've noticed - 660S has a noticeable accent on the lower middle of about 400-700 Hz (in 800S it is also noticeable, but a little less) - because of this hum, vocalists gain 40kg of weight and violins turn into violas )) In general, 660S2 seemed the most even and versatile from this four. Good headphones.
I own both the 660s and s2 (only picked up the s2 because of the internet hype that it was an upgrade over the old). The old 660s sounds more natural with better clarity to me, the s2 seems to take the warmth a bit too far. If I were to recommend the 660 to anyone, I would suggest picking up the 660s for cheap on second hand market…they could easily be eq’d to match the signature of the S2.
The HD 800S sounds the most neutral out of all of them, at least, through my Sundara... the others are either muddy, or fatiguingly bright. And yes, i have parametric EQ active with a profile tailored specifically to my Sundara.
Mind you, the 800S became EXTREMELY dark over the years by thickening the metal fiber aeras. To the point they not only hold almost no resemblance to the original 800 anymore, but sound even darker than the 660
@@Anti-FreedomD.P.R.ofSouthKorea it seem logic in the video weirdly the 800s seemed heavily boosted in the lower mid-bass like 100hz maybe it sound almost drowned and lack a lot of upper mid-range so it sounded like voice was under something heavy but upper tremble seemed present but hided by this hollow bass do you think the 660s2 is great or should i get the more clinical focal clear. Sorry for this long message also bad english french...
@@Anti-FreedomD.P.R.ofSouthKorea I am French. This is what Senneizer doesn't like, he modifies the sound of the same reference without signaling it. I have the 2022 HD600 and the sound is identical to the 2022 HD650 with supporting measurements.

I agree i’ve heard the 660S and it’s not worth it’s price, the singer in songs are covered by a blanket due to the veil and it is annoying, EQ does remove some of the veil but the issue is that you lose dynamics, however it did add a bit of detail in the high mids and the treble region but somehow the low mids get recessed. Judging by this video the veil is still an issue on the HD660 S2 and the new model sounds even worse it seems

@@yosoy1loco Hi there. I appreciate your detailed comment. I spent the last two days listening to the HD660S2s after receiving them and I am very pleased with how they sound; I'll just refer to them as S2s. Just as a note: I haven't owned any "audiophile headphones" before these; the main headphones I use daily are the Bose QC45s. I mention this because I have no reference point with people's comments about how the S2s "are an upgrade to the 660s, 650, etc. " I am not an audiophile by any means so I'll try to explain the best I can. Bass-wise, it really surprised me. Full, rich, and to the point that I can "feel" the music, just like if I placed my ear next to a large party speaker and felt the vibration graze my ears. I listen to a wide variety of music but the one instrument I've been denied from appreciating with my Bose was the bass guitar. With the S2s, I can finally hear its deep rumble when it's plucked. Mids are clear; I can appreciate all of the instruments and pinpoint what is playing. Highs are powerful but not to the point where it's too bright or unbearable. Male and female singer's voices are sharp and slightly recessed as compared with the other instruments. This was something I was not used to and initially, was disappointed in. However, what I found great after listening for hours is that my ears never grew tired, no matter how loud my music got. I guess I still need to get used to this. Soundstage-wise, its quite narrow. I was not expecting it to mimic some great orchestra hall but can now see what people are talking/complaining about. What I mean is that instead of the music having a spacious, airy feeling, it simply feels like that the musicians/singers are in a small circle right at your ears (hopefully this makes sense). Imaging is fantastic. I can hear instruments that I did not hear before plus can easily sense where they are (i.e. in front, side, or behind me). In my opinion, these are fantastic headphones and I am enjoying them even more each day. They are paired with a Fiio K7 dac/amp
I agree judging by the sound demo i find that the original sounds much better however the veil bothers me a lot and i’m surprised why the 660S is so appreciated
