May 13 (Reuters) - Apple ( AAPL ) is gearing up to sell

its Vision Pro mixed-reality headset outside the United States,

Bloomberg News reported on Monday, in a bid to invigorate demand

for its most expensive bet in years.

The iPhone-maker has flown hundreds of employees from its

international stores to Cupertino, California and started

training them on how to demonstrate the $3,499 headset to

customers, the report added, citing people with knowledge of the

matter.

Apple ( AAPL ) plans to bring its Vision Pro to international markets

after its Worldwide Developers Conference (WWDC), scheduled to

be held from June 10 to June 14, the report said.

The training of workers, which takes as many as four days,

from Germany, France, Australia, Japan, South Korea, Singapore

and China, suggests these will be some of the first

international markets for the device.

Apple ( AAPL ) did not immediately respond to a Reuters request for

comment.

The Vision Pro headset was unveiled in June last year and

hit the shelves in the U.S. from Feb. 2. The headset's launch in

the international markets could help Apple ( AAPL ) attract customers at

a time when sales of its most popular product iPhone are

slowing.

After initial enthusiasm for the Vision Pro, which has a

hefty price tag, the demand has been slowing, according to

analysts.

In March, Apple ( AAPL ) CEO Tim Cook was quoted in China's state-run

CCTV Finance saying that Apple's ( AAPL ) Vision Pro will hit the

mainland China market this year and that the company will

continue to ramp up research and development investment in

China.
