The company sent an email asking customers to check their earphone software has been updated.
Amazon has warned its wireless earphones may be at risk of overheating and is urging customers to update their software, to make them safe.
Customers were sent an email on Wednesday, saying in “very rare cases” Echo Buds could overheat in their charging case.
Amazon said it had released a software update to fix the issue “out of an abundance of caution”.
“The safety of our customers is our top priority,” it said.
It is not clear if Amazon engineers discovered the issue themselves or if a real-world incident sparked the advisory.
