I know that the current trend is all about smart speakers, but since we have discussed that topic extensively in recent editorials, I thought the time was ripe to discuss what is happening with headphones, a still-growing market segment showing some signs that deserve attention. In this article I wrote for The Audio Voice newsletter, I address ongoing trends in design choices, user preferences, frequency response curves, and personalization.

Even is reinventing personal audio with technology that tunes sound to each listener’s unique hearing with its patent-pending Even EarPrint process. A veteran group of sound designers, acoustic engineers, mastering technicians, and audiologists have perfected a personalization process for headphones and earphones that measures the user’s reactions to a series of eight different frequencies in each ear in only 90 seconds.

Since 2009, Vesper has built a broad and deep patent portfolio around its proprietary MEMS piezoelectric technology, which works quite differently from conventional capacitive MEMS microphones. As Matt Crowley, CEO of Vesper, says during an interview with Voice Coil, “We are just beginning to realize the potential of piezoelectric MEMS microphones.” This article was originally published in Voice Coil, December 2016.

Today, most audio products, from Bluetooth speakers to appliances with voice command, now contain at least one microphone. If the product was designed a couple of years ago, it had an electret condenser microphone (ECM), but today it will most likely use a MicroElectrical-Mechanical System (MEMS) microphone. Spec’ing MEMS microphones has some differences and this article touches upon these points.
