A federal judge has substantially narrowed a class-action lawsuit alleging a condensation defect in Apple's AirPods Max. Brooklyn federal judge Orelia E. Merchant dismissed most claims, particularly those brought under New York law, meaning they cannot be refiled. The original lawsuit, filed by users Arthur Apicella and Dustin Amundson, claimed moisture formation inside the aluminum ear cups caused connectivity, sound quality, and battery issues.

Judge Merchant dismissed all claims filed by Arthur Apicella with prejudice. This includes allegations of breached warranties, concealed defects, and unjust enrichment. However, the lawsuit will continue based on Dustin Amundson's complaint, though his express warranty and unjust enrichment claims were also dismissed.

Amundson can still pursue claims under Washington state law regarding implied warranty of merchantability and the federal Magnuson-Moss Warranty Act. The judge reasoned that New York's implied warranty only requires a minimal level of quality, and the AirPods Max performed their basic function. Amundson has until August 5 to request permission to revive additional claims.
