STORY: Apple is getting ready to launch its Vision Pro mixed-reality headset in markets outside the U.S.

That's according to a report by Bloomberg on Monday.

It says the tech giant has flown hundreds of staff from its overseas stores to California for training.

The workers involved come from Germany, France, Australia, Japan, South Korea, Singapore and China - hinting that these may be the first international markets for the device.

Bloomberg says the overseas launch could come after the firm's Worldwide Developers Conference in June.

That could be timely for Apple, which is looking for a sales boost amid waning demand for its iPhones.

But, at $3,499, many question whether the Vision Pro can ever be a mass-market device.

It was unveiled in June last year, and hit U.S. store shelves in February.

The headset allows users to blend reality with immersive video.

After an initial surge of sales, analysts say demand for the gadget has since tapered off.

There was no comment on the latest reports from Apple.

Back in March, Chinese media quoted Chief Executive Tim Cook as saying the Vision Pro could go on sale there this year.
