The measurements for the in-ears are quite simple, so I’ll put the final implementation first, since it would be too little for a longer talk. By the way, I use a good Bluetooth 5.1 dongle for wireless devices, which does not struggle to connect and provides the common codecs. The whole thing will look like the next picture. You just have to find the silicone pad that sticks tightly. But since the transducer is standardized, one pad will always fit.
Now let’s move on to the on-ear, supraaural cushion headphones. We can see very well in the picture how the pad nestles on the ear and also gives in some places (which is the whole point). Despite the applied fit, the earpiece closes really tight, which is also due to the generated pressure. You can see the slightly tilted position of the adjusted transducer at the bottom, so that the receiver is sufficiently tightened analogously to the fit on the head.
By the way, I made a second cushion that is easy to replace and does away with the silicone ear. The opening is smaller and only extends the axis of the tube on the measuring microphone. Then you end up with a very simplified solution, the results of which I will write about in the over-ears, because the measured values differ greatly in direct comparison. But more on that in a moment.
Finally, we are of course interested in the measurement of the over-ears with the silicone ear and the support plate, i.e. the circumaural headphones including all the problems. This is where it gets really interesting and I have the first measurements for you on the next page, which were taken before the final calibration. Maybe some feedback from the readers will help to include one or the other change, because I don’t have exclusive knowledge either and I always like to learn more.
