You could be forgiven for thinking these Aircore OWH headphones were designed by Apple. In fact they're by Shenzhen-based audio technology company Movengine. The unusual donut-shaped cans provide, the company claims, a "soundstage"-like effect "as if you were surrounded by HiFi speakers." They also reckon there's a comfort advantage to the pass-through design:"Unlike traditional designs that seal off your ears, AirCore OWH eliminates direct pressure on your ear canals, allowing for longer, more comfortable listening sessions. Enjoy a feather-light fit with zero ear fatigue--just pure, effortless sound." The Aircores weigh 309g (11 oz), which is significantly lighter than Apple's AirPods Max, which weigh in at 384g (13.6 oz). However, Sony's WH-1000XM5 take the lightness crown at just 250g (8.8 oz). Should you want to listen to something bass-heavy, or block out all external sound, included silicone caps can be used to plug the holes. One thing the open-ear design precludes is, of course, noise-canceling. That aside, the Aircores have been successfully Kickstarted, with 42 days left to pledge at press time. Buy-in starts at $149, and they'll ship in June.
