The HD 600-series - A Hi-Fi Family | Sennheiser 

Actually, the older HD650 can be better than the newer ones

Thanks for sharing your feedback. Enjoy!

@@sennheiser Isn’t the HD660S 150ohms?

Same! I own a pair of HD660S and love em. Didn't know the difference between the membrane materials.

i love your profile picture!! daft punk is the best :)

Thanks so much!

Thanks much and thx for trusting Sennheiser with your listening needs!

Hi. I've had the 599SE for about 25 days and decide to try the 560S because I saw the reviews saying they're far better. And I agree, so I'm returning the 599SE. However, now I'm thinking of really stretching out and getting one of the HD 600 series (probably the 600 or maybe even the 650). My main concern is my digital piano (although I will use the headphones for daily tasks on my PC, which is my main entertainment device). It's absolutely top of the range hybrid piano and has good Onkyo amplifiers inside, so I could really tell the improvement going form the 599SE to the 560S. With that in mind, in your experience, if I stretch to the 600 series will I notice a significant improvement/difference? The most important aspect to me is that the piano sounds as natural as possible (the way that the included VST was designed to sound by the Kawai/Onkyo engineers), without the headphones being too tiring if I'm practicing many hours a day. Thank you!

@@zvelekva The 560S is a darn good headphone. It's detailed, balanced and very flexible (easy) to drive. When I listen back to back with my HD6XX and HD660S there is a noticeable improvement in the size of the sound image with the 6 series. They sound richer and more full overall. As far as piano in particular I do think the 6 series provide a more enjoyable tone due the magical mid range the 6 series is know for. An example I can use is Tori Amos whose main instrument is the piano. Listening on the 560S everything is clean and balanced. But when I switch to the HD6XX her voice and music just sound elevated, sweeter and more engaging. More like a live performance. They are so easy crank and not feel fatigue from the extra volume. Moving to the HD660S provides even more detail along with the elevated sound although some of the "sweetness" goes away. At this point I'm excited to try the new HD660S2 but I'm going to wait until the price comes down a bit. I think you have a solid sound with the HD560S and many find it to be there endgame. Having said that the HD6XX is capable of delivering an even better experience when amplified well for not much more money. HD6XX for the win. There's a reason this ancient headphone is still being made. 😁

@@ClintAvila Thanks, much appreciated.

Thanks ol buddy!

On my nearly 20 year old set of 600's myself! Thx for watching!

@@EricPalonen HD600 should be in every collection of audio enthusiast 👍 they are long living legends. Love their "analog" sound paired with tube amp, sweet mid range

@@soulfulfool amen you said it best! An icon! Glad you discovered them and their magical pairings 💪

Why do you have 3? Do you use them for different genres?

They are indeed related

Yes @sennheiser. Please make a guide on about all the 500 series headphones.

My relations with HD600 are like I'm about to sell them, than I listen to them and I can not do that :). They are not perfect but it has excellent timbre & mid range, highs and lows are decent

new pads for 660s? pls give me a link.

@@benegesserit9838 search new pads clear ring

@@Tripokaridos22 oh lol. indeed

Same. They are my dailies. I own other exotic planar and dynamic driver cans but the HD660S are all round great. Non fatiguing, precise, tonally pleasant, soundstage and detail perfect for gaming. Voices clear with any form of entertainment media. Holding their own with most genres of music. Their only weakness are a lacking low end. They are not bass head cans and that's totally fine for daily usage. I've got other cans for that. Sheep skin pads help with that though.

yeahp also my HD660s are myfavorite and honestly most people on this hoby if they have to choose one good all arounder HD660s would be the best.

@@CidiousX A lot of people say the weakness is the low end.. But i am 100% sure that with EQ they get a lot of Bass without distortion on lopgical volume. FOcal Clears fore example or ELEX or HD 560s they have distortion way faster. And also i have use EQ and Harman EQ and didnt like it . I prefer the default tuning because without low end and that small bump on High bass note is that warm feeling that u dont have with EQ.

I use them with an ifi hip DAC and they're plenty loud enough without needing high gain, and the X-Bass integrated sub-bass EQ is a match made in heaven imo. I'll probably pick up a Zen DAC V2 at some point.

In fact, I'm so enamoured with the HD660S sound that I'll likely be buying the IE 300 for my portable needs. I guess I'm a Sennheiser fan!

@@elliotclarke5685 Hip DAC and the HD 660S are a great combo!

huh duh six hungeos by ol mate senni

660S is 150-ohm. All the 600 series products are Made in Ireland.

​@@rags015 Sorry, you're misinformed. The 600 Series are made in Ireland. The factory in Tullamore is fully operational. And since the sale of the consumer audio division to Sonova, the factories role has expanded. Products like the HD 800S and HD 820 that had been assembled in the German HQ facility are now made in Ireland. The physical production line for those products were moved. There are press releases on line that outline all of this info about the facility in Tullamore and what is produced there.

@@rags015 you could listen to an Ireland HD 800S and a German HD 800S blindfolded and never know the difference in build or sound. They are built, tested, and released to spec.

no thank you, very ugly, new ones looks better

@@JohnSmith-zl8rz New one is boring and generic looking. The marble design is part of the history and legacy of the 600s. Hence why people are paying more for used marbled Irish 600s than these brand new Romanian made 600s.

@@k-lawn both sounds the same and the end that's the important thing, I buy the new ones today.

@@k-lawn New design is much better and is basically just HD 650 design adopted on HD 600 design as well. HD 650 was always more expensive option than HD 600...

I was about to say that but you beat me to it.

And in reality it goes up to 420 ohms just like the other 2...lol

No revisions that I'm aware of. 660S is 150-ohm.

HD600 maybe yes. But the others are more for listening music and all round usage. They are a bit colored. For studio usage I'd more look got the Beyer dynamics DT1990 with better detail in the highs. HD600 series is very mid range focussed. Great for vocals and although very detailed in comparison to some other cans not extraordinary at that. My HD660s aren't neutral either. They need some equalization to remove a bit of veil over the sound. Beyers DT1990 will serve this purpose better.

@@rags015 Yeah you're right. It's makes me worried for the future of Sennheiser, the decision reflects an image that they don't recognize and respect their own past.

@@deusern It´s not the same company anyway. Sennheiser sold it´s consumer branch to Swiss company Sonova (not a bad company on it´s own though)

150ohms is their impedance but it's misleading, the sensitivity is the same so they are as hard to drive as the other (HD600s)

@@sennheiser So HD660s2 use Steel Mesh... Thank u a lot

@@Tripokaridos22 Happy to help!

we all know the reference. m8

Better than the dirty buds!

I FEEL your passion! Sennheiser did a press release, Head-Fi Post, and even a video interview between DMS and representatives of Sennheiser Consumer and Sonova. Essentially, Sennheiser’s consumer division had hit a plateau, and was looking to grow and wanted some help to invest back into the business. At the same time, Sonova had a good medical hearing products business, and was looking for a ready-made solution to enter the consumer business. It was a great match for both companies because Sonova gets to enjoy the experienced engineers, mangers, assembly workers, and advanced facilities of Sennheiser, while Sennheiser found a partner that respected their heritage and direction that had already been mapped out (like the recent releases of the HD 560S, IE 300, and IE 900). Both companies are excited to continue production of classic models and the extra resources to make new consumer goods… and I mean the employees too, like the Irish facility in Tullamore that has been employing locals to produce flagship headphones and components for Sennheiser since the 90’s. Some consumer production had briefly been moved to Romania to be manufactured and assembled alongside the Pro products (the drivers still came from Ireland), but now consumer is back in the factory that was built for it. Engineers and portfolio managers are still constantly tinkering away and testing in Germany, and the three or so QC checks performed on each unit is still performed by the same people (Sennheiser has been producing Instagram Reels lately showing assembly and QC, which is cool for me because I’ve never been to Ireland myself). If anything, all that sounds like positive news to me, more security that we will continue getting the classics as well as pushing to create new goodies.

ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-PC4HUvQvago.html DMS is actually a company rep for a competitor, Abyss Audio, so it’s a very third party host interviewing the Sennheiser and Sonova reps 😂

The HD 600 Series is and has been for years manufactured in a Sennheiser owned facility in Tullamore, Ireland. This includes transducer manufacture and final assembly of the headphones. The transducers are computer tested individually to reference specification, then once assembled the headphones are also computer tested against reference performance parameters to insure they are meeting specification before they are packaged.

FiiO Q3

Correct, 150 ohms

Correvcy, 150 ohms

Any comments be greatly appreciated, cheers

@@davidwright2379 The BTR5 does an ok job so long as you are using the 2.5mm balanced output jack, as this has more power than the 3.5m jack (where you may have to max the vol on source and on BTR5 and it may still not be loud enough for you) so it's worthwhile finding a balanced cable. Or bump up to the BTR7 or maybe a non-bluetooth DAC with a usb-c/lightning input for your source (laptop, phone)?

@@Neil_Mackie hi Neil, thanks for the comments, much appreciated mate, actually picked up a balanced cable 2.5mm from Amazon, with the btr5 and Drop hd58x, sounds amazing to be honest, such improvement from the 3.5mm stock cable, will see how this goes, but plan is to upgrade to btr7 in next few months Cheers David

@@davidwright2379 That's great! I've done back to back with 3.5mm vs 2.5mm on the BTR5 and 3.5mm vs 4.4mm on the BTR7 and apart from slight volume changes there is a slight increase in clarity or separation of instruments. Of course it could all just be a placebo but if it makes me happier over spending time and money on these things then that's great!

@@Neil_Mackie absolutely Neil, noticed a real difference using the 2.5mm balanced cable, definitely more power, less volume on both the btr5 and mobile device, soundstage improved, just a way better overall sound and enjoyment factors, and I do recommend that Drop hd58x, can't best the value for money, and a great purchase experience from Drop. Cheers mate, David

I‘ve read everywhere that the HD 400 Pro sounds the same as the HD 560S, not the HD 650 (which I own btw). According to this youtuber, Sennheiser themselves have confirmed that: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-NJf0HkmIdq8.html

What’s an entry level headphone in your opinion?
