This elevated treble is mostly responsible for the perceived high detail. Max. cont. Below the HD800 CSD plots as a comparison. Nevertheless Etymotic does it a lot better. What can be observed as well is that there is some ringing visible in a high frequency (10kHz). The HD800 is somewhat more ‘grating’ in the treble but that is really the only audible difference to me. A ‘horizontal‘ frequency response curve on the shown frequency response plots on this website thus indicates a perceived ‘flat’ tonal signature. Fortunately there are fixes for this that do not affect the other excellent qualities. Cable entry: dual sided In other words, an ideal frequency response is one that doesn’t adjust the volume of the bass, middle, or treble, from our source. The distortion around 60Hz is around 1% So even if your frequency response chart from Senn had a dead flat line, your headphone's actual frequency response is far from flat. Equipment Forums. It's important to note that Sennheiser modeled the HD800 series' frequency response on the sound of a neutral speaker in an anechoic room. Below the frequency response of the HD800S (Left, Right). First, the full frequency response (not truncated to 12KHz) of HD800 and on more clearly disclosed equipment: And perhaps of most interest to the OP, the bassy sound of the Beats isn't all that … Senn draws attention to the fact for marketing purposes. A different plot is the spectrum plot. The step response clearly shows the lack of ‘bottom end’ as evidenced by the downwards sloping line. The treble quality is better than that of the HD800. Also the frequency range of the spectrum plot is wider (from 100Hz instead of 500Hz). Cable: 3m 6.3mm TRS +  balanced 4-pin XLR cable. However, the bass … Hmm.. It's important to note that Sennheiser modeled the HD800 series' frequency response on the sound of a neutral speaker in an anechoic room. Most prefer a laid back sound, and some of the detail hidden so they can't hear the defects in their music. Foldable: No Technically an excellent (maybe close to the being the best) headphone but to me a bit still a bit too bright and too ‘lean’. Headphone cup connector: proprietary ODU GmbH 2 pin connectors. The only thing you can take from these is a verification that they put it through some quality test. The new design is claimed to deliver a slightly wider frequency response of 4Hz to 51kHz (at a rather generous -10dB), where the original was rated at 6Hz to 51kHz. The shape of your head, bone structure, pad size, pad ‘softness,  (compliance), hair or no hair and or wearing glasses may (drastically) change the frequency response of some headphones, so… your personal experience may differ substantially from these plots. The elevated treble and slightly rolled off subbass are still downsides. Headphones with a good sub-bass extension have a (close to) horizontal line after the initial rise. The CSD shows a quite good response with no obvious and deal-breaking resonances or lingering. By comparison, if you’ve messed around with any music app’s EQ settings, you might have seen a non-flat EQ setting that boosts bass or cuts treble, etc.So if a component (such as a headphone driver) doesn’t have a flat frequency response… They sound fine by me. Below the distortion plot of the HD800 (measured under better surrounding conditions). The differences in drivers exist because of production tolerances. Distortion from 200Hz to 10kHz is very low. They have an almost neutral frequency response and … What can be seen is the superior initial rising flank which stops at 2dB below the 0dB line. From 10Hz to 1kHz the differences are negligible. The result is hyper fast response for superb detail across the entire frequency range. Small and short lived resonances can be seen at 6kHz and 10kHz though but doubt these … In addition to the standard 1/4" stereo … Max.

What is obvious here is that the dip after the initial rise is deeper and that the resonance after it is lower in frequency (6kHz) and takes about twice as long long to die out. Forums. :(. However, they do cost quite a sum at $1295.00 and $1399.95 for the T1 and the HD800, … Clamping force: very low. It seems to take away some of the sparkle but causes the overall warmth to get accentuated a bit. The similarities are very obvious. Below 100Hz this headphone drops off very gradually. It is marketed next to the HD800 and not a replacement. A reduction of about 5 dB is achieved. Bass integrates seamlessly with the mids. That appears to be a pretty … The small dip from 1.5kHz to 5kHz may be a little less ‘deep’ in reality compared to the measurement  because the measurement rig does not have a pinna which does alter the response exactly in that area. Higher 2nd harmonic distortion in the bass. Given that headroom’s normalization to 0 dB at 1 kHz seems to be about 3 dB too high to me, the bass gets to its -3 dB point at about 12 Hz (!). It shows the HD800S is well damped and even at low frequencies it shows a very fast decay. This means our ears will also have a narrow dip somewhere in this region. By lack of oscilloscope shots (not enough time to measure that) below a step response plot of the HD800S (Left, Right). Based on the research of how human ears hear, headphones' frequency response should not be flat, and should be based on the diffuse-field frequency response, which has a big bump at high … Press question mark to learn the rest of the keyboard shortcuts, HeaDSPeaker -> Nuraphone | Stax 003, 202 | Audioquest Nighthawk, HD800 S | Bifrost MB | Valhalla 2 | JBL 590 | Emotiva A-500, HD800S + Lyr 2 / CA Andromeda / UM Merlin + Sony ZX2, HD 800 + Burson Soloist SL + Musical Fidelity V90 DAC, An entire wall covered in HD600/650s and NFB11s, Audeze EL-8 Ti | Sennheiser HD1 | Solo3 | AirPods. Sennheiser HD800 Certificate for Frequency Response Arrived Home. Perfect seal, seal broken with thin armed glasses, seal broken with thick armed glasses and seal substantially broken by slightly lifting the bottom of the pads a few mm which can occur when not properly seated. It doesn’t look like this will make the difference but it does remove the remaining sharpness but leaves the overall sound completely as it is. The new Sennheiser HD800S absorber reduces unwanted peaks in the headphones frequency response making the listening experience smoother and more balanced. Below the frequency response of the HD700 and HD800 in one plot. Even the HD800S still has some ‘sharpness’ in its sound though and while better than the HD800 already it still needs some EQ. That part is responsible for the fine detail reproduction and instrument ‘placement/localization’. Below the spectrum plot of the HD800S 75YA (Left channel). This way the plots are overlay-ed and it is easier to see how the tonal balance changes. … and an only slightly veiled treble. Instrument separation as well as dynamics and retrieval of the finer nuances is among the best of the TOTL headphones out there. To compensate for this the amplifier is cranked up to the same level (at 1kHz) as the low impedance amplifier. (Right channel only). Sample 1. You can clearly see the influence of the HD800 S -resonator around 6 kHz, how it reduces that peak by 4-5 dB. When comparing the two headphones it shows that the HD800S has slightly higher distortion levels below 100Hz. Impedance: 370 Ω (310Ω DC) NO SMOOTHING is applied to the shown plots. Below in dotted green the perceived response.The treble response is elevated. Pads: replaceable microfiber (Left, Right)Channel matching is excellent as should be expected in this price range. input voltage: 12V rms Type: Over ear, open Max. Page 1 of 1 Start over Page 1 of 1 … Clamping force is very low and because the pads are very large and there is plenty of room in there for even the biggest ears you won’t get sweaty/hot ears. But ringing is also reduced which cannot be seen on this plot. There is a solution for this though. However, for quality phones those differences should be below the percievable layer. Sample 2 (w/ SDR mod) Demo units courtesy of: Frequency Response measurements and graphs for In-Ear Monitors (IEMs) and earphones. That's a lot of relatively new flagship headphones. This can be done digitally (and correct for the bass at the same time) or to build (or buy) a passive filter that sits between the headphone amp and headphone cable. The schematic is shown below. Headphones (full-size) ... are there any known cases of fake hd 800/hd 800s? Those mids are clear and articulate and have a decent presence. A little bit less ‘romantic’ presentation perhaps then it might be worth ‘upgrading’. Their sound quality is excellent and they have a comfortable design you can wear for hours. When I would have to give a very short description it would be this. when connected to a higher output resistance amplifier. As in "those headphones are sooo precise that it really matters" something something. The time span is also bigger in the spectrum plots and expired time is shown from below to top where in the CSD the time is shown from rear to front. This is the strong point of this headphone, along with wearing comfort. The effect of this filter is shown below. The 6kHz peak is still 4dB too high (despite the absorber). Below the distortion plot of the HD800S : (only Right channel shown). Is it worth upgrading from the HD800 ? Output resistances below 33 Ohm have no effect at all. The only … Limited to just 750 pieces … Imaging and stereo separation is top notch. Particularly the 2nd order distortion. … I think the build quality of both headphones are high enough, and I really have no complain with either one. This basically is a CSD (Waterfall) plot but viewed from above where the level differences are colour coded instead of being in the vertical axis. You can still hear deep rumbles but just not on an impressive level unless the recording has way too much lows in it. Accessories: 3m cable with 6.3 TRS connector, balanced cable with XLR4-connector, micro-fiber cleaning cloth, manual, USB flash drive. Below the same data but shown in a percentage scale instead of a dB scale. The treble peak of the original HD800 is already lowered using a resonator in the HD800S. Create a free website or blog at WordPress.com. home, Published: Oct-25-2017, updated Dec-14-2020. A highly detailed and airy sound only lacking a bit in ‘body/grunt’ and subbass but not obviously missing bass. HD800 are at 45000 or so? Page 1 of 1 Start over Page 1 of 1 . Frequency Response: 6–51,000 Hz (-10 dB); 14–44,100 Hz (-3 dB) Contact pressure: approx. The S fixes that to some degree. The bigger the deviation the stronger the effect. Those that find the treble of the HD800S and HD800 SDR mod still a tad too sharp can use a passive filter to lower the (still present) boosted treble a bit. When the lack of bass and elevated treble is something that you don’t particularly like but do like the other great assets of this headphone than the Kameleon or (software) EQ may be a way out. Bass sounds ‘tight’ and very ‘dynamic’ and clean. Weight: 380 g. (without the cable) Special high precision headphone connectors, frequency response-14-44,100 Hz (- 3 dB), nominal impedance-300 ohms, contact pressure-3.4 N (+/- 0.3 N) approximately, transducer principle-Dynamic, … As others have said keep in mind this is a diffuse field equalized headphone. The HD800 does sound a bit less ‘warm’ because of the more elevated treble around 7kHz which ‘overpowers’ the sound in the HD800 way too much. Ah, yes a lack of the 6k peak that actually appears on HD 800 graphs is evident here. Tonal balance is bright and not bassy, overly detailed. Diffuse field is basically the opposite, … Sorry dumb question but are all of the HD 800s tuned differently? The chart that you get is how close your pair matched their target frequency response. This turns the HD800 in an HD800S but with better ‘measured bass performance’ than the HD800S as the distortion of the HD800 is slightly lower than that of the HD800S. Sennheiser HD800 review These Senneheisers offer much, but are beaten by close rivals in important areas Tested at £1000.00 By What Hi-Fi? The connector is a LEMO-type 2-pin connector manufactured by ODU GmbH. S.P.L. Changing the cable is not a bad idea when you don’t like stiff, springy and long cables. below the differenced between a demo HD800S (2016) and a new HD800S 75YA version.There are differences between the 2 headphones but are in the ‘range’ of product variations. The Sennheiser HD 800 has a detailed and balanced mid-range. From 100Hz to 1kHz the response is very flat and accurate. Most people claim it has more/less quality bass but to me it is the same. HD800 veiled in any capacity is hilarious. Its … Subjectivist, Objectivist or Inbetweenivist ? I measured this at 100 dB @ 1 kHz. People usually don't like them because the treble is elevated, and they're too revealing. The striking industrial design combines form and function seamlessly, the layered metal and plastic headband construction attenuating vibrations to the earcups while the handmade microfiber earpads offer exceptional comfort for even long periods of listening enjoyment. IMO that's a very outdated version of neutrality, but Sennheiser stuck by the classic German standards when tuning this thing I guess rather than going the HD 650 route. Frequency response: 6 – 51000 Hz (- 10 dB) THD, total harmonic distortion: 0.02 % (1 kHz 1 Vrms) Contact pressure: ~ 3,4 N (± 0,3 N) On the other hand there is as good as no ringing seen at all. There is a small chance, however, that depending on the shape/ size of the owners head seal may be broken resulting in less (sub)bass. I gotta go back and check it out... Looks pretty solid. The frequency response consistency of the HD 800 S is great. Some other specifications are a frequency response of 4 – 51,000 Hz (+-10dB), 300Ohm impedance and a 0.02% (1kHz, 1Vrms). The differences too. Max. This basically is a CSD (Waterfall) plot but viewed from above where the level differences are colour coded instead of being in the vertical axis. As can be seen the absorber in the HD800S does a good job. That 10kHz peak thus isn’t audible as a peak. The used ‘Helmholtz resonator’ seems to be perfectly tuned to the biggest ‘flaw’ of the HD800. ALL measurements are made with a good SEAL on a flatbed measurement rig. The distortion profile is typical for a dynamic driver. This can make the headphone sound slightly ‘fuller’. Below the measurements of the (brand new) HD800S 75YA. : 128dB This is better in the HD800S but this one still is ‘overly’ trebly/bright and ‘hyper-detailed’ because of the ‘treble plateau’.| Not only the amplitude of the 6kHz resonance is lower in the HD800S but the ringing is also much better damped/shorter lived. That would be free field. Also the frequency range of the spectrum plot is wider (from 100Hz instead of 500Hz). The effect of the absorber is quite obvious. Efficiency: 101dB/1mW  (105dB/1V) Also measured the HD800S 75th anniversary version which has a dark gold-ish color instead of the all black color of the regular HD800S. The Sennheiser HD800S is an open over-ear dynamic headphone. back to Sennheiser To order this you can contact member ‘sorrodje’ at SBAF. This is subtle but noticeable. The 10kHz peak even sticks out 10dB above the rest. What must be understood is that a treble response … drawn current: 40mA The treble response looks fine from 7kHz and up and is well extended. When this level is reduced by EQ one must be careful not to reduce the 10kHz part too much. I do not use smoothing because some info about sound quality is lost when plots are smoothed. Deviations in different severities at different frequency bands have an effect on the sound character. Each HD 800 S Anniversary Edition is delivered directly from our Quality Evaluation department together with a frequency response certificate specific to each headphone. When that level is reduced to the same level as the mids the headphone sounds ‘bland’ and lifeless. As this is a dynamic headphone the frequency response might be amplifier output resistance dependent when certain higher output resistance amplifiers are used. Technical Specifications HD800: – Weight – 330 grams (0.73 pounds) – Frequency Response – -10 decibels ; -3 decibels – Nominal Impedance – 300 Ohms – Transducer – Has a massive 56mm wide … The Sennheiser HD800S is the ‘new & improved’ version of the original HD800, a sound revelation which revolutionized headphone audio when released in early 2009.. Now over six years later comes the updated HD 800S touting improvements in bass response… The HD 700 are made for neutral listening. Inside the box, the Sennheiser HD800s comes with a range of accessories: … Below an aid to help determining the sound character of headphones with relation to the frequency response. Below the CSD of the HD800S (Left and Right channel are superimposed). The CSD shows a quite good response with no obvious and deal-breaking resonances or lingering. You can almost think of it as instead of your pair modeling a flat speaker in that anechoic room, it's modeling a slightly bass boosted speaker with a cut at those high frequencies. The effect is similar to that of the HD800S. Driver size: 56mm, angled 10º For the higher frequencies the absorber does not do anything. 05 September 2009 Even with the treble reduced the detail retrieval and ‘airy’ sound remains… just not overly hyped but just more realistic and less fatiguing. Driver type: dynamic, ring driver Wait a minute.. you mean im supposed to find a thumbdrive with this curve in my hd800's box? Comfort of the HD800S is exactly the same as the HD800 which is very high. The gradual downwards slope is evidence of the slight slope in the bass/sub-bass. power rating: 0.5W Just listen to one, they're anything but. In the bass range, the maximum amount of deviation at 20Hz is about 3dB. Wait, does this mean they've already made more than 7500 units of HD800S? It certainly has resemblance in tonal balance with the HD800. You get about 1dB more lows. Again, though, we see that 5khz peak diminished and the high frequency material … Breaking the seal (improper fit on the head) usually means a loss of (sub)bass. Aside from a small correction of the microphone itself also some correction in the lowest frequencies is applied to the plots to compensate for the perceived loss of bass when using headphones. As can be seen the tonal balance changes just slightly on a very high resistance (120Ω) amplifier. 3.4 N ± 0.3 N More. Frequency response (tonal balance) is the most sound-determining aspect of headphones. Small and short lived resonances can be seen at 6kHz and 10kHz though but doubt these are detrimental to the treble quality. To test this the headphone is measured via different output resistance amplifiers (0.2Ω, 10Ω, 33Ω and 120Ω) On a higher output resistance amplifier the output level will be considerably lower. The shape of the bass response … i'm not sure if … That would be free field. No two pairs are absolutely similar. 3.4 n ± 0.3 n What other items do customers buy after viewing this item? To me the differences between the HD800 and HD800S aren’t that big. I'm not sure, how would that impact the sound? The frequency response of the HD-800s goes spectacularly low. Diffuse field is basically the opposite, where the reflected sound dominates so the sound has no apparent direction. Overview Both the Sennheiser HD 820 and the Sennheiser HD 800 S are awesome! For music, other than classical, the HD800(S) needs some EQ in the treble and the lower bass. What other items do customers buy after viewing this item? Frequency response: 6–51,000 hz (-10 db); 14–44,100 hz (-3 db) Contact pressure: approx. Cookies help us deliver our Services. When you are not afraid of some DIY and don’t need the balanced cable nor the black accents then the SDR mod is a better and cheaper idea or the passive filter which lowers the offending treble peak to desired levels. … The headphone’s vibration damping chassis and inert headband ensure that what you put into the HD 800 S is precisely … And I'm really liking the moderate bass boost you mentioned. Here's my graph from last February, Nice, I'll probably also post mine when I get home :). The price of the HD800S is a lot higher though. By using our Services or clicking I agree, you agree to our use of cookies. This isn’t the cheapest connector around so when looking for a replacement cable be prepared to fork out quite a lot of cash. The HD 800 S has a natural sounding frequency response. It's important to note that Sennheiser modeled the HD800 series' frequency response on the sound of a neutral speaker in an anechoic room. Frequency response HD 800: 14 - 44,100 Hz (-3 dB) 6 - 51,000 Hz (-10 dB) HD 800 S: 10 - 44,100 Hz (-3 dB) 4 - 51,000 Hz (-10 dB) Frequency response diffuse field equalized Nominal impedance 300 Sound … On the other hand, a sense of width is there for much of the mix with the HD 800 S. The HD 800 S gets its emotional lift there moreso from the change in dynamic than the change in width. Stock HD800S and HD800S with passive filter. The reduction achieved by the SDR mod from ‘Sorrodje’ from tellementnomade.org is about the same and can be fitted in the HD800 with some guts and while voiding of the warranty. This headphone is top notch when it concerns fit, finish, looks and craftsmanship. One can retrofit a similar DIY resonator into the HD800 but this requires some (not so difficult) ‘surgery’. Not only because of the color and the absorber that lowers the 6kHz peak somewhat but also because of the extra (balanced) cable that comes with it. Seal can be an issue with closed-back headphones but is usually less of a problem for open headphones. Enjoy music through headphones on a low budget, eal substantially broken by slightly lifting the bottom of the pads. Most measurement sites have some smoothing applied which ‘irons flat’ sharp peaks and ‘wiggles’. The peak around 15kHz is too high to bother anyone and I suspect, along with the 10kHz emphasis is responsible for the excellent imaging (combined with ear-driver distance and angle). Below the differences between the HD800 and HD800S. Yep. The time span is also bigger in the spectrum plots and expired time is shown from below to top where in the CSD the time is shown from rear to front. Press J to jump to the feed. Looking at the frequency response does show a very present, but not necessarily overly emphasized treble response in relation to the midrange and bass. Congrats! This is described HERE in more detail. Isolation: poor (open headphone) The measurement rig has a relatively high 2nd harmonic distortion so numbers below 0.2% (above 200Hz) will be there in reality. Very moderate bass boost (though what's up with the dip around 200-300hz?) I've sent off for mine multiple times but they just don't send it. Inner Pad dimensions: depth font = 21mm, rear = 30mm, Width = 60mm, height = 75mm. Or what people generally refer to as a „frequency response“. It is faster and more reactive in the mids, producing a punchiness to transients in vocals, drums, and percussion. When you like the tonal balance of the HD800 and are only looking for somewhat less ‘sharp’ treble and don’t mind the bass quality to be very slightly different then the HD800S may be an ‘upgrade’. Sennheiser HD800. It is not really overshoot but the 6dB dip following the initial rise is a bit high. . New comments cannot be posted and votes cannot be cast. The thing with the 10kHz peak is that HATS usually have a deep and narrow dip there. Lower bass is not boosted. Usage: Home, studio Sidebar 3: Measurements As Keith Howard wrote in the August 2008 issue, deciding what, exactly, is the optimal frequency response for a pair of headphones is neither obvious nor trivial. Ignore the peaks at 50Hz and 100Hz, they aren’t there in reality but are caused by the measurement rig picking up some hum. Most headphones look like that when you smooth it that much. The fast impulse response of the HD800S is clearly seen as it reaches the 0dB line. With this I mean placement of instruments in the sound field and the ability to perceive them ‘separate’ and ‘realistic’ is excellent. A horizontal line shows audible neutral response in the plots on this website. back to measurements
