Amongst Grell ’s many acquirement are the pattern for Sennheiser ’s super high - endHD 800over - spike earphone and the novel badassIE 800in - spike monitor . To kick back things off , we ask Grell to serve a few questions about the design of these stunner , but he ’ll be string up out in the discussion below address whatever is interesting to you . Now ’s your chance to ask all your burn off questions about the skill of design perfect speech sound .

Q : The HD 800 ’s 56 millimetre transducers — I trust that this is the largest dynamic driver in any headphones decently now ?
As far as I know : yes !
Q : What design challenge does such a big driver pose ?
When just the diam of a traditional transducer is increase the contraceptive diaphragm will make undesirable move in the audible frequency kitchen stove . These movement make free fall and heyday in the frequency reply and a reduction of high frequency reproduction . The answer is the usage of a wideband ring radiator : The diaphragm is paste to an inner lip , the 40 millimeter voice ringlet ( this is more than double the diam of the mediocre voice gyre diameter of full size headphones ! ) , and the stunned flange . The aloofness to a controlling element is even small than it is in a traditional transducer . It leads to a very clean reproduction even in the high frequency range and above ( the last is only interesting for cricket bat 😉 )
Q : And why driver size is important in earpiece ?
The larger the moving orbit of a transducer , the less movement he needs to make to produce a certain Sound Pressure Level . The less movement a transducer needs to make the lower is the THD . A second view : The natural sound line of business assume up a very enceinte arena around the head . To make a lifelike picture of the “ way ” it is necessary to radiate the sound as similar to the natural sound field as potential . This is the 2nd reasonableness for the big diameter and the angled position of the transducer .
Q : What ’s was the biggest challenge in designing the new IS 800s ?
IE 800 ? The biggest challenge was to design a transducers that cover the whole frequency range from 5 Hz to 46500 Hz . But it was definetely deserving the body of work . It reproduce the strait without sentence differences what happens when you expend a multi driver solution . The other matter is how to invalidate the resonance that occur when you put a earphone in your ear canal . The solution is the dampened 2 chamber absorber . It direct to a smoother high frequency replica . Now you’re able to get wind r eastward a litre heights rather of a apex at 7500 Hz !
Q : Earbuds tend not to be very durable … what have you done to assure that these will last long enough to justify the $ 1000 price tag . Do you see people using these on the go or at dwelling house ?
They are definitely designed for the purpose on the go — but you could use them at home as well . We have thought a lot about the lastingness of this earphone : we made the living accommodations out of ceramics , build special easy to modify easy to clean ear adaptors , ramp up in two interlocking to protect the acousics against auricle wax and used a special very long-lived cable length . We incur that most of the defect of stock earphones are induce by broken cables . The defect is settle close to the 3.5 mm connexion jade . So the lower part of the cablegram , from the plug to the splitter is exchangeable .
Q : One of the thing we really have a go at it about Sennheiser is that some of the less expensive headphones are so fantastic …
We live how music sounds . A mint of Sennheiser employees are DJs , musicians , sound technologist or Tonmeisters . We have a lot of a experience with the right tuning of earphone . We know how a headphone should sound and we know it better than some gangsters 😉 It is possible for us to make a good sounding headphone even when cheap ingredient , but of course of instruction in direct comparision you will hear the difference to a top class headphone
