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.

Review Image by C. A. Bayko C. A. Bayko
I am semi-retired, but back on the road full-time air travel weekly. For years I have been buying high-end headphones, in the $500-$2800. range. I spend hours reading reviews, analyzing cables and Daps. I use most items a short time, sell them at a loss, and pursue the next great sound. It is important to me travelling 80% of the time, to be able to have my home listening experience on the road, because when I'm travelling, that is my life. So knowing that I have had Sennheiser, Oppo, Focal, Sony, Audeze, Grado & Mr. Speakers to name a few. This is important for you to understand as to why my review is such. There are many variables influencing sound, the quality of the file, the cable, the DAC /AMP, and the actual Headphones. Knowing that, when we look at HP reviews we have to carefully look at those variables, as well as the listeners preferences, to determine how the review applies to you. In my case the music I like is Jazz, Classical, singer /songwriter and Broadway and Movie Soundtracks. Across all of the years, the most fascinating pair of headphones I ever owned was the Sennheiser H800. The soundstage, detail, timber, the note extension, the air were aspects I never experienced with any other headphones. I always went back to the HD800s as a reference sound, to check the tonality of a voice, the depth of strings, the quality of an oboe or flute, the strike of a piano key. The treble could get a little sibilant, and the bass a little lean, but they sparkled. I sold them because they were open, I was seldom home and I seldom listened to them. Recently back on the road, and after purchasing the most high-end DAP /AMP I had ever owned the Cayin N8, I searched again for a good closed back sound. The Sony WMZ 1000v3, Focal Elegia, Mr Speakers C, AKG N90, Sony 1ZR, I was considering the new Focal Stellia. I became aware of the Sennheiser HD820, never knowing they had been released. From the moment I put them on, the reference level sound I remember came back to me. The depth, the sparkle, the range, the timber, taking a semi-sibilant alto vocal, and giving it breadth, neutral and sibilance gone. I know I didn't want the Senns because of the 300 Ohms, and dependence upon an amp, but I have to say, they sing like no other. I've had them about 2 weeks, have about 50 hours on them. I bought a Moon Audio Black Dragon Premium balanced cable, to replace the long stock cable, with a shorter length for travel, more durable connectors and best sound. I bought the Accessory House Global 2XL case for travel. Have worn them on 8 flights. They are noise isolating, and frankly good enough where I can enjoy the music. I'm not really a fan of "electronic" headphones. I have felt, when I retire officially these Sennheiser HD820 and my Sony Z1R are my end game headphones. I've been through everything but electrostats, and these give me awesome reference sound and snuggle warmth with the Sony's. After purchasing I still follow reviews and keep reading the that the Sennheiser are at a High end Treble peaky, and the Sony's are more warm, and maybe something like the Focal Stella and Meize Empyrean are the in the middle, not sibilant, not bassy, but best all arounders. So this morning I'm thinking how can what I hear be so different. How can I think the HD820s 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!) ... show more

I waited 3 years to save up for these headphones. I am not disappointed. The sound is incredible. Very, very clear. Rich midtones and vocals. Sharp, thumping bass. Incredible treble high notes. Perfect separation of instruments. Never dull or muddy. Running with Mojo 2 DAC-Amp which really does the job ... show more

    • Be careful with ordering these through Amazon
I ordered a pair of these a couple weeks ago as a huge audiophile and after test driving a pair at a local A/V store - huge upgrade and would've been fantastic *if I wasn't sent a broken used pair on the first go*. The earcups didn't have the new sticker on them that comes with the pair and there was no audio coming from the right earcup. After unplugging the cable to inspect it was apparent that the two copper prongs that connect to the headset just weren't even there; completely broken from the cable. 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. ... show more

    • good
i have these and the 800s. 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. ... show more

    • HD800 or HD820?
With HDVD800 as amp, I brought HD650 (6 years ago), HD800 (4 years?) as well as HD820 (1 year?) (All HD8XX are using Sennheiser offical XLR-3 cable). 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. ... show more
