I asked some IEM company just a couple, at most, years ago about have NO Wires at all on them. Because they ALL use a wire that's about the size of a couple HAIRS. They told Me that would be impossible. Now they're everywhere.

613MemberIf we take an HD Bluetooth signal, and have a DSP, basically, directly driving the lowest possible mass/high stiffness MEMS transducers, you will get quality; it is headed this way. We will be getting better miniature solid state batteries at an affordable cost, hopefully soon to enable these to be truly right-sized... http://www.fdk.com/whatsnew-e/release20190509-e.html They will all need a complimentary wireless 'do-not-lose' locator phone app as well... All should remember, in all this; Bluetooth is just a code(ec) that was utilizing a junk band that couldn’t travel further than we could throw (various stuff); that became useful in this new wonderful connected world; that will become more of an HMI - because the codec allows it to utilize WiFi bands; Bluetooth then becomes Mastertooth... and we get gobs of sq:)) score 1 for the Consumer team! The King rises again, watery tart & sword, nice hat...

Wired ones you can buy now... not a bad deal, really, when you think how early an adopter you would be... 1st gen $821.48 (someone buy and review;) https://www.digikey.com/en/product-highlight/u/usound/megaclite-3-0-earphones Paper: https://athena.usound.com/download/mems-speakers-whitepaper/ Interestingly moving towards possible multiple-material arrays with varying sized diaphragms; poshing-off the Si folks... just stiffing them ultrasonically;) "Megaclite 3.0 is a set of USB-C earphones. It features the new USound piezoelectric MEMS speaker technology. Megaclite presents a distinctive sound that sets it apart from balanced armature and electrodynamic earphones designs.
