xMEMS Labs, the leader in solid-state MEMS audio solutions, today announced that its breakthrough Cypress full-range MEMS speaker, together with the Alta-S companion drive ASIC, is now ready for mass production. This milestone represents the industry's first commercially viable full-range solid-state audio solution capable of meeting the demanding Sound Pressure Level (SPL) requirements for noise-cancelling true wireless stereo (TWS) earbuds.

With Cypress' silicon diaphragm, monolithic solid-state construction, lightning-fast mechanical response, and flat, near-zero phase response, earbuds can now achieve wider-bandwidth noise suppression, improved passive noise isolation, and unprecedented sound clarity in a package just 46 mm³ and weighing only 98 milligrams.
