Wear detection pauses audio content when the headphones detect that you've removed them from your head, and resumes content when you put them back on. Apple's AirPods Max and Bose's QC Ultra 2 perform this feature best by pausing content when you remove the headphones and disconnecting them from your phone's Bluetooth. This allows you to switch audio from the headphones to your phone without pressing a button.
Maybe it's because I personally shelled out $350 for a pair myself, but as a tech expert who's been testing gadgets for a decade, this is hands down one of the best Prime Day deals I've seen so far. The Sony WH-1000XM4 headphonesalso known by the much more readable name "Sony XM4"just plummeted to the lowest price I've ever seen. They're now just $188 at 46 percent off their original price on Amazon. Am I bitter that I paid full price? No ... definitely not.
