Sony's new around-the-neck style wireless headphone, the WI-1000X, costs a whopping $300 (£300, AU$449). Why so much? Well, it's one of the few in-ear wireless headphones with active noise cancelling and also packs in several other features, including Atmospheric Pressure Optimizing that's supposed to help optimize noise-cancelling performance on planes.
The pricey around-the-neck WI-1000X wireless noise-cancelling headphone is set to take on Bose's QuietComfort 30.
