Since March 2026, EchoEar-Blue-EN has been changed to ESP-VoCat. The product name and related documents on our official website have now been updated to ESP-VoCat. However, due to existing inventory, the physical packaging of the stock still bears the original name, EchoEar. During this transition period, there may be instances where the name on the sales link does not match the name on the physical packaging. We hereby provide this explanation for your reference. ^^ a 1.85 -inch QSPI circular touch screen, dual microphone array, and supports offline voice wake-up and sound source localization algorithms ^^ suitable for voice interaction products that require large model capabilities, such as toys, smart speakers, and smart central control systems.
