Just days after Apple unveiled a new hearing aid feature for its second-generation AirPods Pro, the U.S. Food and Drug Administration (FDA) has granted approval for the software behind this functionality. In a press release, the FDA referred to Apple’s solution as “the first over-the-counter (OTC) hearing aid software device.”

Apple, in response, stated that it respects its employees’ rights to discuss wages, hours, and working conditions, as reflected in its policies. The company expressed its disagreement with the allegations and intends to present its case during the hearing scheduled for January, if a settlement isn’t reached.

The ability to use AirPods Pro as clinical-grade hearing aids is one of several new features Apple is introducing to the second-generation AirPods Pro this fall, as part of its ongoing commitment to hearing health. The earbuds will also include a Hearing Protection mode that shields ears in noisy environments like concerts. This mode, enabled by default, will maintain “natural and vibrant” sound quality at live performances.

Apart from Gjovik’s case, Apple is also facing other pending NLRB cases, including accusations of wrongful termination at its Cupertino headquarters and interference with a union campaign at an Atlanta retail store. The company denies all allegations.
