BTR11

BTR11 has a built-in independent headphone power amplifier chip with ultra-low internal resistance and an output power of up to 45mW (162), which is enough for the earplugs to perform excellently. Through Bluetooth wireless, you can also enjoy high-quality music comparable to wired connections.

BTR11 has a built-in rechargeable battery, which can work for 15 hours when listening to music continuously. When the battery is low, it only takes 1 hour to charge to 90%, which is close to full power. It is also compatible with mobile phone data cable charging using Type-C interface, and supports positive and reverse plugging.

It has a built-in high-sensitivity omnidirectional microphone and supports call noise reduction, providing a clear call experience.

The body is equipped with a red and blue dual-color indicator light, and the clever display combination can intuitively indicate power on and off, pairing, charging, low power and 3 Bluetooth formats.
