For example, in the song Highways and Clouds by Amos Lee, his voice seems to sit more evenly in the mix when I was listening to the HD 800 S. However, the HD 820’s boost helps melodies in strings, pianos, synths (etc), especially in meaty arrangements, stay on top so they are easy to follow and don’t disappear in the thickness. He's written about music for publications like Filter and Under the Radar and about politics for publications like New Republic, Jacobin, and Dissent. In general, the biggest difference between the Sennheiser HD 820 and the Sennheiser HD 800 S is, of course, one has a closed-back design, and the other has an open-back design, respectively. Both have the same nominal impedance (300 ohms) and nearly the same sensitivity (103 dB for the HD820 and 102 dB for the HD800s). In general, the biggest difference between the Sennheiser HD 820 and the Sennheiser HD 800 S is, of course, one has a closed-back design, and the other has an open-back design, respectively.

The two share the same ring diaphragm and Helmholtz resonator design, and they both use the same connectors (now in black for the HD 800 S). First few days impressions THE TREBLE: Tie HD800S keeps up the brilliance of OG HD800 (owned this a few yr ago), but dials it down to the level where it rides the cutting edge of being brilliant yet not irritating like the OG HD800 can be. After getting my speakers, Piega Premium 5.2, but especially the Focal Electra 1028, I found myself to listen to them on fewer and fewer occasions. The HD820, according to Grell, would have a small dip between 150hz to 200hz in order to compensate for the resonances of closed-back cans, allowing the the HD820 to possess the extra bass thump of closed cans without “blur[ring]the mid details.”. Sennheiser used a Lehman Audio headphone amp, beyerdynamic used their individual A1 headphone amp. The HD 820 has a boost in the high part of the lows, almost bordering on the low-mids. As a fellow HD800S fan, and having heard the the HD820 at various shows, your impressions are spot on. If the HD820’s build and presentation share much in common with the HD800S’s, its sound is where it deviates. 00. Conversely, the HD 820 demonstrates more contrast in the soundstage. However, the HD 800 S has an emphasis that is a little bit higher, bordering the lower high frequencies whereas the HD 820’s is a little bit lower in the high-mids. Underneath its fancy Gorilla glass exterior, the HD820 shares much in common with Sennheiser’s open flagship HD800 and its revised incarnation, the HD800S (U.S. MSRP $1,699), which I’ll be reviewing in this piece to provide a comparison with the HD820. Freed from the sometimes piercing high end of the HD800, it’s easy to enjoy the HD800S’s impressive soundstage (or “headstage”), which is arguably the widest and deepest of any set of cans currently available. The price of the HD800S is a lot higher though. Like the HD800S, the HD820 comes in a rigid storage box. It's easy! Tags : HD800S, HD800s vs HD800, Sennheiser HD800S review. Introduction. The HD 820’s lows are modest in volume, although have a feeling of evenness and realism to them. (I had to travel couple of hundred miles to audition these) I have heard the HD800S before many times, and still with the massive soundstage it "wow'ed" me. The German company has taken what was a … Could this be the headphone that finally delivers a reference level, open back experience in a fully sealed, noise isolating design? In short, with the HD800S, Sennheiser has turned the flawed HD800 into a more balanced, more competent all-around headphone that now has to be the go-to set of cans for audiophiles seeking out the best detail and soundstage possible. Hopefully, as was the case with the HD800, Sennheiser will release a revision of the HD820 in the not-too-distant future that remedies its flaws and keeps its strengths. As a result, neither is really better or worse, they’re just different. Over the new few months, I’ll be reviewing a few of these new entrants into the closed-back market. There’s also the fact that, despite being a closed can, the HD820 (red) don’t isolate better than vented closed cans like the aforementioned Atticus (orange), which lacks the HD820’s soundstage, microdetail, and low bass extension, but bests the HD820 on overall dynamics, smoothness, and (crucially) tonal balance: Whereas the HD800S can now stand toe-to-toe (and often best) any open can in its price range, the HD820 are hard to recommend over another warm-leaning closed can like the Atticus, which (at a U.S. MSRP of $1,099) happens to come in at less than half the price of the HD820.
