But the fact that they removed the hard case. Shortened the cables. And raised the price. I feel like they are not doing right by us. They come out to $650 including tax. If they really wanted to hit it out of the ballpark they should have lowered the price especially considering they reduced what they include in the box. They would have sold these in the tens of thousands immediately. Now people are going to sit on the sidelines and wait. I know these will drop in price eventually. The fact that you can get the 660s for under $300 now and of course the original HD 6XX for around $200 makes these seem like a money grab. I do believe they are improved and they probably are the best version but are they really worth $650?! Sorry Sennheiser I will be patient and wait for the price to be more appropriate.
I fully agree, but. my 650s have served me so well as daily drivers. I've changed the pads 2 times and had them for like 10 years, then the 580s before that. While I agree on the money grab part, I'm ready to give sennhiser my money for the s2s. I'm forever a fan from all the enjoyment I've gotten. $600 is a lot of money for me, but I'd pay it 3 times over for how good this company has given me music and comfort.

@@Flashtone08 please let us know your thoughts when you get them. Two reviews from the Headphone show are out and they are describing a very different sound then how these are being marketed.

Looks like we're already getting differing opinions on whether or not these are better than the original 660S and 650.
one of the best reviews so far. i love the 660S so much as soon as i saw the pre orders i ordered the S2. Pricey but i use them EVERY single day just like I did with S1 and considering they last years it was worth it to me. I think the extra bass makes it sound more balance
Just ordered 660S, I think it’s a good price at $309 (tax included). The new version must be nice but not worth the asking price, unless you gotta have them now. I don’t. Maybe in a couple of years , or sooner, when the price will drop. But not now.
I got these and the meze 109 pro. I feel like the mezes are waaay to bright to me. The are on point to me. Just wish they had slight more soundststage. But imagein and seperation is just on point
While I enjoyed this review, currently, the S1 has generally been on sale for $ 399 CAD vs $ 799 CAD and is not worth the price in upgrading. If I were picking at current prices, I'd go S1.
Hi according to Jason from custom cans it doesn’t change the soundstage that much, how the look at his video and his frequency plot yiu see what I mean , yes the s2 is a bit better but I found my 6xx is not far off . Regards mark
I'm looking forward to seeing more reviews before I pull the trigger on these or the Mezo 109Pro. I love my HD-600's and HD650's but would like more bass extention. I'll be comparing them to the HFM Sundara. .
Hi again I now recently bought open box s2 for £269 and yes more bass , and agree with your earlier subs that it’s very expensive in relation to the s , don’t get posh box for example . Regards mark
The sound on the HD660s2 is really impressive. The bass does go down to lower actives. The bass is not necessary louder but it goes down to lower frequencies and you can hear the instruments. You can hear the buzz from the guitar amp. Much more detail and not in your face highs. More relaxed. Good for rock. Ipad - Amazon Music HD Jeff Beck Wired 360 Wired. Using a Tube Quad PA-one DAC. You really hear much more detail and the sound is much more full than the HD600. The clamping force on the headphone is a bit strong. Hope it loosens up.
I have both and I decided to keep the S2 and sell HD660S. It took me a while to get used to the soundstage of S2. It sounds like half way Spatial Audio , Dolby. Great for classical or movies but not so much for pop music. The sound of S2 is growing on me. I find the S1 more engaging. The sound is closer to your ears. The drums kick harder. You feel the music much better. The siblings are more pronounced on S1. Almost non existent on S2 if at all. S2 takes the music and moves it 3 meters back, great for long listening sessions. The S1, is more in your face type of sound, but not as close as Grado. Coming from Grado 325, I’m used to that sound and I prefer it over a more spatial sound with a wide soundstage. But , I also like contrasts. So because I already have Grado, it makes more sense to go with a wider sound stage and keep the S2. S1 feels a bit tighter when you have them on.
I have 660S and 660S2 here... About 8h I try them in comparison out... I have to say... the 660S is still better. Just with deep Sounds and Bass, the 660S2 is stronger.
Interesting video, I noticed in the Uk that now available £409 cheapest Amazon and other main hifi outlets going for £429. I totally agree with the comments before me it’s way over priced considering it doesn’t come with that nice box and shorter leads, I bought my 6xx recently and the same thing happened with the box and shorten cables as well made in Romania not Ireland . Regards mark
The big Question is ... Does s2 give something more other than extra Bass that can be Eq on S1 ? Are they better on Imaging , speed, detail, etch etch ?
This is the only question that matters. From what I understood was that no, these do nothing special, but in fact have a standing wave issue making them objectively worse.
I've owned multiple 6XX models. The HD600 were my go-to. That's because they captured the essence of music, but lacked treble and sub bass. The 800S had more of both and a big sense of space. This year, I took delivery of the 660s2. They are (obviously) superior to any of the other 6XX. In fact, aside from sheer space, I like them as much as the 800S. The 660s2's basic frequency response is just as good and natural. So much so, I sold my 800S and 6xx models. The 660s2 are my primary cans and I want for nothing else. if anything the 800S are a ripoff and vastly overpriced, not the 660s2.
In my experience, after listening to HD 660S, HD 800S, and HD 660S2, I feel like it's not worth it. Despite the fact that the base is good, the tonal balance and timbre of HD 660S2 are not up to the mark; actually, it actually hurts my ear with higher peak frequencies. HD 660S2 tries to mimic HD 800S sound but fails so badly. Sorry, but it's not worth it for me. I now respect HD 800S and 660S more.
I have both the 560s, 660s and 660s2. The 560s are much better for gaming compared to the 660s, but there were a few times the 660s were clearer and that made the difference in scenes with a ton of sound effects going on. The 660s2 does something incredible though, and essentially does everything the 560s did for gaming, but has much more precision and clarity. The 560s still has a bigger sound stage, but the 660s2 is so immersive and precise it truly feels like a gaming upgrade from the 560s. The 660s is still good, but I feel like if you have the money or find a sale, then the 660s2 is worth it without a doubt.
@antoniocecere9648 It is more spacial like the 560s. There is still intimacy in the vocals, and they never feel drowned out, but they do convey a little distance now. The separation between the layers of music or gaming is incredible though.
Hi also I do have 6xx with customer cans bass mod which does improve the bass at the bottom end , but nobody as yet done a review on the 6xx against the 660s2 be interesting what’s the findings. At the moment some of the hifi outlets are doing these headphones for £379 in the Uk . Regards mark
@@qwertyrewtywyterty I do agree with your finding and also over the hd660s I have too, but as I said been fitting thicker ear pads to see to help with the bass as my old hd575 has thicker pads over the stick pads now fitted to sennheiser phones
@6643bear using bass mods will reduce the soundstage right? because it will sound more like close back headphone. I prefer the natural detailed bass on the 660s2. And compared to 6xx, the 6xx is lacking in the sub bass, too much mid bass
I've had the 580s and 650s, I was never a fan of the cables as they always seem to short out with how I use headphones. After market has served me well. Excited for the 660s2 and happy to pay the pre order cost, but first thing I'll do is replace the cable. Yes we all know this headphone will likely be $200 cheaper in a few years. So get it then if you want them.
