Customers say
Customers give positive feedback about the translation earbuds’ quality and communication ability, with one customer noting how it helps communicate with locals with confidence. However, the translation performance receives mixed reviews, with some finding it accurate while others report slow Thai to English translation. Moreover, the functionality, ease of use, and value for money are also mixed aspects, with some finding it worth the price while others consider it a waste of money. Additionally, customers report a delay of 2 to 5 seconds during translation.
