 This is a Bloomberg Money Minute. Apple's Vision Pro mixed reality headset seems to be struggling to find takers. The $3,500 device has yet to sell 100,000 units in each quarter since its U.S. launch in February. And according to market tracker IDC, it faces a 75% drop in domestic sales July through September. The researchers say while June's international launch will offset weaknesses in the U.S., total sales are unlikely to top 500,000 units this year.
