From the paper[1] since the website fails to explain this (!):<p>> Earables are ear-worn devices that offer functionalities beyond
basic audio in- and output. In this paper we present the ongoing de-
velopment of a new, open-source, Arduino-based earable platform
called OpenEarable. It is based on standard components, is easy to
manufacture and costs roughly $40 per device at batch size ten.<p>> We demonstrate the versatility of the prototyping
platform through three different example application scenarios.<p>The three example apps are:<p>> Measuring motion on the ear is a common application in the earable
space which can be used for a number of applications<p>> A popular ear canal pressure application is the detection of jaw
motions<p>> It is possible for the ultrasonic microphone to pick up an inaudible
signal from the speaker. This information can be used to understand
the shape of the ear canal because the sound is reflected differently
depending on the shape, a principle which can be used for authentication<p>The paper also mentioned ClearBuds[1] which looks interesting too.<p>[1] <a href="https://open-earable.teco.edu/OpenEarable.pdf" rel="nofollow noreferrer">https://open-earable.teco.edu/OpenEarable.pdf</a><p>[2] <a href="https://clearbuds.cs.washington.edu/" rel="nofollow noreferrer">https://clearbuds.cs.washington.edu/</a>

Do you need one for left and one for right ear, or just one of either?<p>If just one of either, how do you decide which one to get?<p>On the one hand, if I am right handed, I might find it more easy to quickly take it on and off if it's on the right side. But at the same time, that would also mean that whenever I answer my phone I'd also have to take it out first. Unless it can also be paired with the phone and used when answering calls.
