MEMS microphones are almost replacing the condenser microphones. Mems can be integrated,compact and with stands more vibrations without performance degradation.Also they are manufactured within plus minus 3 db sensitivity which means less difficulty for the manufacturers to test their products for its uniformity. The analog devices makes it with 62-dB (typical) signal-to-noise ratio (SNR), 20-kg and 160-dB mechanical and sound-pressure shocks, respectively, and power supply rejection ratios (PSRRs) of 80 dB (digital version) and 50 dB (analog version).
I'm looking forward to improved feedback systems in noise cancelling headphones. Who knows, maybe they will be able to design a product that cancels noise over the full frequency range, not just "airplane noise".
I agree. I got the chance to test some MEMS microphones from Wolfston last year. I compared them to the standard Electret microphones and there was no comparison. The MEMS are far superior, lighter and more sensitive.
There is no doubt in my mind that Electrets are dead. If your product isn't using MEMS, then your customers will want better.
Just my opinion.
