---|---|---|
Around-the-EarLuxuriously soft earpads rest around the ear for long-term comfort. |
Closed EarcupsEscape your environment with a sealed design that attenuates the noise around you. |
WiredComes with (2) cables for connecting to singled ended 1/4-inch (6.3mm) and balanced 4.4mm Pentaconn outputs such as headphone amplifiers, A/V receivers, audio interfaces and more. |
Reflecting Within
The reference-class experience of the HD 820 is achieved with the use of precision concave glass reflectors, one capping each earcup. These functional plates reflect energy from the rear of the driver to a specially tuned absorber system, allowing the waves to mimic the behavior of open headphones such as the HD 800 S. The result is a sound stage never before experienced in a sealed headphone. The headphone’s vibration damping headband provides complete stability while reducing crosstalk. What you put into the HD 820 is precisely what you will get out of it. Each transducer is manufactured, tested, and measured to an extremely tight tolerance to ensure the most dependable performance out of the box. Each HD 820 also includes the frequency response plot unique to that set’s serial number, sparing no resource to help you retrieve the most critical details from every corner of your music collection.
Fellowship of the Ring
The 56mm Ring Radiator transducer found in the HD 820 leverages the key benefit of a large diaphragm speaker—air displacement. Both outer and inner edges of the “ring” are secured to the drive unit to keep it rigid for fast rest and response times. The result is accurate response spanning the entire frequency spectrum.
Let’s take a look at the specifications...
- Frequency response: 6 – 48,000 Hz
- Impedance: 300 Ohms
- THD: <0.02%
- Sensitivity: 103 dB at 1 kHz, 1V

Product Description
The new audiophile standard for closed-back headphones for audiophiles there wasn't any doubt: When it came to circumaural headphones the very best sound required an open back design. This axiom has now been rendered obsolete by the youngest member of the Sennheiser Audiophile Range: The closed dynamic HD 820 employ an innovative technology that makes them sound breathtakingly transparent and natural. Developed and made in Germany they offer an incredibly realistic natural sound field and also stand apart by the extraordinary attention given to every detail of their design. Their soft comfortable microfiber ear pads are hand crafted providing excellent attenuation of ambient noise while the robust metal headband includes an inner damping element. Get ready for an unparalleled listening experience. Into the great wide open vivid wide transparent natural. The sound field of the HD 820 is wide open. Which is not what you would expect at all from closed circumaural headphones. With the HD 820 you can explore and rediscover your music in absolute reference-class quality without intruding on the aural comfort zone of others. Thus the HD 820 not only open up the sound field but also new places and opportunities for you to enjoy your music. The Technology of Transparency The breakthrough transparent performance of the HD 820 has been achieved through a special innovation: Their legendary Sennheiser Ring Radiator transducers are fitted with unique glass covers. Revealing the great look of the technical component within this visually striking feature was actually developed wholly in service to the sound: The concave glass reflects the sound waves from the rear of the transducer to an absorber which results in minimal resonance. Thus the sound waves are effectively gone like they would be in open headphones. An all-star team of excellent components made in Germany the HD 820 stand apart also because of the extraordinary attention that is given to ever.

are the best all arounders for me. Every HP is a compromise somewhere, but I think the HD 820s are the most enjoyable and perfect. So I did a comparison between the HD820s powered by the Cayin N8 balanced, and my Sony NW zx300. In the quiet of my home I Listened to a high resolution file of DreamBoat Annie, one of my all time favorites, for dynamics, sparkle, bass, mids and treble and soundstage. On the Sony ZX300 the top end sounded thin, in fact a tad sibilant, the whole sound lacked the end game sound I had been hearing. I went to the Cayin N8, Ahh...Sennheiser HD820 I am fully satisfied with, the comfort, the build quality and the sound, what more could I want. So I know there are others out there buy .High-end Headphones, and search for great sound. Sound is subjective, but I have learned a lot from other reviewers, in order to gain a perspective. Get confused by some reviews that raise a product on a pedestal, and others that say the same product is middling. I know this is a long review, without measurements and spectrum comparisons. But I hope it will help others. No single Headphone does it all. but in your private listening room, I am convinced that the Sennheiser deliver everything anyone would ever want, and if stuck on an island or stopping all future purchases with the HD820, you will enjoy them, you will hear detail you never knew was there, transported to another realm, and enjoy the music, taking into consideration all the variables. Using the N8 and quality files, there is no fatiguing highs, and there is plenty of bass, and everything in the middle. This may be my last HP review, thank you amazon for the opportunity to share and help others in the community, enjoy the music, Chip out!* (*reference to guru Tyl Herstens, who I followed for years, and is now downsized and enjoying the world! God Bless on your Journey!)

After returning those I had to place another order as Amazon wouldn't do an exchange and the box I received looked as though it was used as a rugby ball at some point. Clearly opened, cables a mess throughout the box, and this time while there was audio it was crackled throughout. My assumption is these were open box rebranded as new and the cables were swapped out because there's no reason a new and clean cable would be that bad of quality.
After 2 passes of returns I'm going to just pick up a pair locally where I can open it in store.
800s have better midrange, probably because they are open.
I hate discribing how headphones sound because the words one typically uses are so subjective but I would say the 820s have a fuller low/mid-low end and less soundstage overall. also less fidelity on the high end.
I EQ the h*ll out of the source when I use headphones with perimetric eq (fredenstein f610 and midias 512/522) on line level signal and use a heritage audio system 500 amp for the headphones.
both 800s and 820 take eq like a champ, impossible to overdo it, eq amps will clip before the headphone drivers overextend. very impressive.
the 800s can be eq to do almost anything the 820s can on the low end but the 820s are capable of more low end at the end of the day. probably because they are closed.
overall 800s have more fidelity and 820 have more low end. both are worth the money if your in this price range.
i use both about 50/50 and I use them a lot. very good headphones. I have had k701, bunch of audiotech brand and bunch of sennheiser brand. they all rot on the shelf now.
Overall experience proved HD800 performs better than HD820. So my conclusion is that if you are not using headset in noisy environment then HD800 would be better choice. Maybe HD820 suites office environment better.

Reviewed in Mexico on July 21, 2023
der 820 hat ein deutlich schmaleres Klangbild, wirkt manchmal wie aus der Dose. Es sind nicht nur die Frequenzen unterhalb von 1000 Hz, sondern das gesamte Klangbild wirkt eingeengt. Wenn ich das mit den Superanzeigen von SENNHEISER vergleiche und den Tests vom angeblich besten Kopfhörer der Welt, dann liegt es vielleicht an meinen Ohren, daß ich dem nicht folgen kann. MfG, Alexander
