Sennheiser’s HDV 820 is the next generation of its acclaimed digital headphones amplifier, designed to complete the Sennheiser audio experience and perfectly complement its high-end audiophile headphone range for the ultimate acoustic performance.
The perfect partner for reference-class headphones
There are two things that mark a quest for perfection: It is never completed, and it has the potential to bring out the most extraordinary things with the power to shape the future within its field. Enter the HDV 820, which will surely change the way you listen to and experience your music. That is, if you are lucky enough to possess headphones capable of turning the extremely high-quality audio signal delivered by the HDV 820 into an aural quality just as supreme.ones.
The mission: Better the best
When you have engineered audio components that represent the state of the art, going one better is the most rewarding task we at Sennheiser can think of. It was the task we set out on when we designed the HDV 820. Pioneering into new technological territory, we found still more sonic truth to bring to our most demanding clientele.
The sound: Making great headphones show all their class
Virtually everything. That is what the HDV 820 will give to your headphones. So, it will be up to them to make it heard. The different timbres of two otherwise identical instruments. The distance between the musicians of an orchestra, the tension before a singer delivers the first note. It is all there, for you to discover.
The technology: Only the unsurpassed
The higher the tech, the higher the emotion. The heart of the new HDV 820 is a formidable ESS SABRE32 DAC (digital-to-analog converter) that surpasses the previous generation with an even higher resolution of 32 bits and a sampling rate of up to 384 kHz. The amplifier is also capable of playing DSD256 files of up to 12.3 MHz.
The design: Giving the eyes a taste of how it sounds
Fittingly for an audio component that delivers such an incredibly pure sonic experience, the HDV 820 has also been created to delight visually. It features a new anodized black finish with white LED lights that has been designed to perfectly complement the latest version of our flagship high-end headphone, the HD 800 S – by the way, an ideal partnership for the ultimate audiophile listening experience.
The compatibility Outstanding sound will find a way
With a breadth of audio outputs that include XLR3, XLR4, 6.3 mm- and a 4.4 mm Pentaconn socket, it is easy to find the optimal way to connect your headphones with the HDV 820. It performs brilliantly with digital sources, whether optically, coaxially, or via USB, and features balanced (XLR) and unbalanced (RCA) analogue inputs. The HDV 820 also comes supplied with a dedicated, country-specific power cable.

The spinfit w1 is a cool eartip , fits in well , as the eartip is translucent the bass is less , but the clarity is good
When you talk about audio, I feel like you always have to define your baseline because the experience is so subjective. In that sense, before I bought these IEMs, my daily listening device was Sennheiser HD 598S, so thats what I'm going to largely compare it to. Also I've now been using the earphones for more than a year, so this will be like a long term review.
My main reason for purchasing IEMs was that good headphones are simply not portable. I wanted something that I could take anywhere, and would sound good on mobile hardware as well. It was bit of a weird thing to go for a portable device that would be more than twice as expensive as my daily driver, but after doing a lot of research on audiophile websites, I realised that this thing here was in somewhat of a unique space in what it offered for the price range.
The first thing I noticed after getting these IEMs, even before the burning in period, was the sheer clarity of sound, specifically till the high mids. The vocals sounded crystal clear compared to my 598S, and although Sennheisers are generally considered strong in their mid range, and that is true when it comes to the power, they didn't hold a candle to the Blessing 2s when it comes to precision. It shouldn't have been that much of a surprise really, considering the Blessing 2s are couple of price brackets above, but having never had a proper IEM before, I was truly surprised something with such a small form factor could sound so good. Needless to say that my old daily driver was summarily drawered (binned is too harsh), and has been sat there collecting dust.
Even though this has a dedicated dynamic driver for bass frequencies, bass is not that powerful on this device. I'm not a basshead by any margin, but I would have like just a bit more punch. That said though, the clarity here also is very good compared to my old sennheisers, and I've grown to enjoy the subtle bass now. Its a bit like when you move from putting sachets of sugar in your tea to just one. Feels not enough in the beginning, but soon enough your taste buds get used to it. Our ear's sensitivity is not static, so don't worry too much about this.
What can definitely be seen as bit of a con though is that the highs are not that great. There is a shrillness and edginess to them that could use more work. If you listen to stuff that has a lot of high frequencies, this might not be for you.
That's it about the tonal quality. Since this is a long term review, I'll talk a bit about more practical things also, like the build and ergonomics.
First off, the modules themselves are quite large. I don't have small ears, but they do stick out a little and look like hearing aid devices which people with hearing deficiencies use. And all that largeness is not just for show, they are also slightly weighty compared to a lot of other IEMs I've held.
The cord that these things come with is gorgeous. It looks good, feels good, and holds good. I think even in 5 years time, the cord will still be pristine.
The earbuds that come with this are of three different sizes, and you get 2 pairs of each size. Unfortunately, there is no notch or lip on the tapered end of the module to hold the earbuds in place. Fairly soon, you'll find the earbuds slipping out and falling down, or remaining stuck in your ear while you pull the earphone out, which can be a bit annoying. To fix this I purchased some buds of one size smaller, so that they'd fit tightly and hopefully hold, but that also did not work for long. Finally, I've simply resorted to gluing the earbuds with fevikwick. Not the best experience here.
Another thing that I wish I'd known earlier is that the resin body, which is transparent and looks lovely, is extremely brittle, although it feels very smooth and you'd think that it might have some pliability. Resting your IEMs on a hard surface like a desk, will produce a sharp "clack" sound and after a while you may start noticing that the resin is cracking. I'd suggest to always place them in the case they come with, or on some soft padded object. Even when you've plugged them in, rest the actual modules in the case when not using.
Thats it for the review. Props to you if you read all that.
TL;DR knowing how they are now, would I make the same purchase again if I could go back in time? Abso-damn-lutely.
Quality and works as it is described
I didn't realize how good these sounded until I plugged them into Tempotec V6 using the balanced connection. Technically sound and quite musical. Performs excellent with more power. Truly a champ..bye bye Monk plus...
It was problematic from day 2 it was always stopping in the midde and its kinda irritating
Fiio cable refined music and better sound generated
The cable has stood the test of time well so far. Can't complain!
A must have dongle DacAmp for anyone who wants to drive their IEM's to the limit.
This IEM will stay with me for a very long time. Superb for daily listening and also an excellent refrence point for premium IEM's.
Superb player at the price point
Excellent cables. Using it with Monarch MK2 which has decent stock cables, but Dromi definitely takes it to the next level.
Amazed by the sound output and the clarity that it produces, You can really feel the difference in the sound when you use your earphones without this DAC, and even better is the price that you get it for and would definitely recommend for someone who is looking for a DAC in a budget.
The sound quality is fantastic, with the right amount of bass and treble. Adds more punch and juice when used with a DAC and the sound will blow you.
