       | This is pretty cool. Crazy price though (guess more of a devkit).
       | Hopefully this will get adopted by others like Apple.

       | Despite their recent massive flops in the AI department, in a way
       | this makes me excited about Apple's prospects in this regard in
       | the long term. These are bigger than AirPods, but they're not
       | _that_ much bigger. Shave off the USB-C connector for wireless
       | charging, swap the battery out to accommodate for the shape and
       | you're already pretty close. Apple is really good at fitting
       | things into the smallest form factor possible, and given they
       | could offload all the compute to the iPhone which already comes
       | with some pretty good chips, this could lead to some really
       | exciting tech in the long run. They need to get their act
       | together before that can happen though.

       | What is the weight of one of these ear buds? I guess too much
       | weight can easily give you head aches. On the other hand, it
       | seems from the pics that further miniaturization is possible.

         | My boss actually switched to wearing them all day dogfooding
         | the thing (I work in the same lab: also as a disclosure). For a
         | long time a downside was the audio, but the new version has a
         | really nice driver and amazing DSP optimizations. The
         | colleagues also conducted wearability studies and I also can
         | confirm (having participated) that they are really walearable.
         | Don't have the numbers but they are not really heavier than
         | other in ears from my impression.

           | I see "Ear Canal Pressure Sensor" is listed on the website.
           | 
           | I know that NASA was doing some research on using the
           | tympanic membrane to measure intercranial pressure. Ask
           | around, please, and find out if anyone has considered that
           | application. We really do need a better way to detect
           | cerebrospinal leak (CSF Leaks). A CSF Leak was a significant
           | contribution to my late wife's death.

             | constantly for new applications (particularly in health

             | tensor timpani muscle activity [0] .

         | It is fully open HW packed with not so cheap sensors and also a
         | bit tricky to assemble. Target group for assembled devices are
         | mostly other research labs. My colleague who developed the
         | thing actually is thinking about a cheap version. However, the
         | USP are all the sensors.

       | I was actively looking for something like this and had found this
       | last week. Pine buds pro is another option that gives you quite a
       | lot of control with access to the firmware. But I cant seem to
       | get my hands on any of them. Either the custom duty doubles the
       | price or it is too costly.
       | 
       | Nonetheless open-source ear buds is a big need for the
       | engineering and hacker community.

         | things.
         | 
         | My first project would be exercise monitoring. You can measure
         | heart rate, blood oxygen levels, and body temperature in one
         | place.
         | 
         | I would then add something fun like comparing beats per minute
         | of the music to heart rate.
         | 
         | I like the creators' suggestion of using the shape of the ear
         | canal for authentication, I bet that's harder to steal off a
         | video recording than fingerprints or a retinal pattern.
         | 
         | I'd also use this for voiceless speech, as the creators
         | suggest.
         | 
         | I could think of more, but I won't be able to afford the dev
         | kit, sadly.

       | This is very cool project I need to say. I really like all the
       | things that you build on top of that. I had no idea about the
       | BMA550 accelerometer usage to detect speech and silences, it's
       | very very cool.
       | 
       | Regarding the IMU, it mentioned the MM-FIT for workouts, but I
       | checked the code and it's not used at all, no?
       | 
       | Good job, awesome product :-)

       | I have previously purchased and written[1] about the Tympan.org
       | open source hardware hearing aid[2], but it's about $300 which I
       | can reasonably purchase.
       | 
       | If this comes down in price, I'd love to build some neat things
       | with this hardware.
