دليل مستخدم سماعات بلوتوث Avantree AS50

مقدمة

The Avantree AS50 is a versatile pair of Bluetooth 5.0 over-ear headphones. While primarily designed for seamless integration with the Avantree Ensemble wireless TV set, it functions independently as a comfortable and lightweight Bluetooth headphone for use with mobile devices, PCs, and other Bluetooth-enabled audio sources. Key features include an extended battery life of up to 35 hours and FastStream Bluetooth technology for a virtually unnoticeable lip-sync delay when paired with compatible devices.
