Sony Group Corp has paused production of its PSVR2 headset until it clears a backlog of unsold units, according to people familiar with its plans, adding to doubts about the appeal of virtual reality gadgets.

Sales of the US$550 (RM2,596) wearable accessory to the PlayStation 5 have slowed progressively since its launch and stocks of the device are building up, according to the people, who asked not to be named as the information is not public. Sony has produced well over two million units of the product launched in February of last year, the people said.
