Not an issue for me, as I rarely have time to listen longer than 2-3 hours per day.



Agreed, but isn't treble quality supposed to be *the* strong point of all MEMS?



... done.
Hence the early raving of the treble in the Creative. At least that is what I have been reading. Bass might need burn in, tips and/or EQ. There might be some bugs to work out in the software as well it seems esp. with certain phone pairings. Treble seems to certainly be the strong point so far.

Yup, but after seeing those measurements, I reserve the right to be skeptical. Lack of high treble doesn't necessarily mean they don't sound crisp, but rather that they may lack air and stage may feel small. Gonna see for myself, that's why I ordered them. There's no risk involved, worst case I have to pay return shipping to Creative.

Yes the creative app does reset the EQ to flat randomly, sometimes it uses the EQ I set. The cavity for the buds in the case is quite spacious, so it can accommodate quite a large third party tip. I put on the Sony wf1000xm5 tips and the passive isolation is better and makes the sound a tad warmer.

Getting back to mems vs xmems, the way I understand it is that heretofore, mems tech in audio had only been employed for microphones. I'm not an electrical engineer, but it seems to me signal capture is a very different problem than signal reproduction. What xmems has for their solution, from the silicon surface over the piezo electric substrate to their custom amp, is unique and has no rival.

The tech is called MEMS for speakers as well as mics. Xmems and Usound are the first two companies producing MEMS speakers. Very similar tech from both.

That just means that both speaker solutions are of a Micro ElectroMechanical System , and apples and oranges are both fruit.

Alright, I found a statement about the working principles of MEMS speakers here, which should help to clarify the differences a bit:
The MEMS (Microelectromechanical systems) technology is new to the world of the loudspeakers.

Several companies are developing MEMS-loudspeakers using different technology principles, Audiopixels, xMEMS, we at USound, and several other new players.

Audiopixels uses the “Digital Sound Reconstruction” (DSR) concept, which generates the desired sound waves by using arrays of actuators.

xMEMS technology is based on “speaker cells”, where depending on the applications a single or a group of speakers cells can be used.

USound's loudspeakers resemble the traditional loudspeakers, retaining mechanical elements such as acoustic plate and acoustic membrane while replacing the voice coil and the magnet through a MEMS actuator.

Also, there's this description from manufacturer Soranik, who's IEMs combine both an xMEMS and Usound speaker:
Vietnamese audio company Soranik has released the world’s first in-ear monitors based on a pair of MEMS solid-state drivers . The Soranik MEMS-2 headphones use a 6-mm MEMS USound Conamara supertweeter, which, with a low level of distortion, is capable of operating at frequencies up to 80 kHz. MEMS Montara is responsible for the full audio range, with a flat frequency response of 20 Hz-20 kHz and a phase deviation of only +/-1. A crossover was not needed in this case.

Personally, I think you can put the emphasis on differences and say they're like apples and oranges. Or you can put the emphasis on similarities and say they're more like Gala and Granny Smith. Either way is fine with me, I'm not interested in arguing with anyone, only interested in learning the facts.

Good stuff, thanks. I promise not to make a joke about Apple getting into the game.

After reading that, I see why xmems solid state manufacturing is supposed to be a big deal, especially if these can be used in arrays where timing would be extra important. Meanwhile usound claims 80k(!) reproduction.
