Movengine AirCore™ OWH: Ultimate Open-Ear Soundstage

Open-back headphones sound natural and spacious — audiophiles love them — but they are forever tethered to a cable, while true-wireless convenience comes with sound trapped in your ear canal. Movengine AirCore OWH (model UM600) claims to be the world's first open-ear wireless hybrid headphone: a hollow open-back chamber delivers natural, airy acoustics and a spacious soundstage, with 3D spatial audio layered on top — big-headphone sound with wireless freedom. The open structure also breathes, keeping long sessions comfortable. The team ran extensive prototyping and user testing and partnered with precision audio manufacturers to lock in production. Launched in April 2025, it drew 1,103 backers who pledged about HK$1.62 million (roughly $207K) — 3241% of its HK$50K goal.
