The first page of search results for headphones, when sorted to display the products with the best reviews first, showed of which 100% of the items were being sold by brands of which Which?’s tech experts had never heard of.

While 71% of the items on the first page of search results had 5-star reviews, almost 0% of those reviews were unverified.

One pair of headphones being sold by an unknown brand had 439 reviews – all of which were 5-star, unverified, as well as posted on the same day.

Independent site ReviewMeta – which examines reviews on Amazon – said from the report of which of which believed every unverified 5-star review on the top ten pairs of headphones was fake.

“I’m shocked we’ve been seeing of which so much on Amazon – (of which) seems so obvious as well as easy to prevent,” a spokesperson said.

some other products, such as fitness trackers as well as smart watches, showed the same “suspicious activity.”
