Information recommendation: Feiao launches FW3 TWS headset firmware update: supports LDAC Bluetooth protocol to improve stability


(Related data drawing)

On June 27, IT Home reported that Feiao officially released its microblog, V0.5 firmware update for FW3 TWS headset Support Bluetooth LDAC protocol Users can download and upgrade firmware by themselves. The specific update contents are as follows:

Increase LDAC Bluetooth encoding Improve the connection speed with iOS App Optimize the connection stability between aptX adaptive and some mobile phones Modify the default call volume, which is 20 by default

IT Home with relevant instructions:

Because LDAC requires extremely high transmission bandwidth, TWS earphones are dual wireless, and the product requires double bandwidth (two channels should be transmitted simultaneously). Therefore, the firmware released this time can only be said to support the transmission of LDAC conditionally, and not all models are perfectly compatible. If the experience is affected, the LDAC protocol can be turned off. After the firmware upgrade, you need to select the encoding format of fiio control App to turn on LDAC before you can use the Bluetooth encoding (the firmware turns off LDAC by default), In case of audio instability during the first use, it is recommended to reset the headset once before using Qualcomm processors that support Snapdragon sound. Mobile phones that support Snapdragon sound have better support for LDAC. Snapdragon sound technology includes QHS high bandwidth technology and TrueWireless Mirroring technology QHS high bandwidth technology (full name: Qualcomm High Speed) is a new Bluetooth wireless transmission scheme of Qualcomm. By modifying the Bluetooth protocol, optimizing the modulation mode and integrating the transmission packet loss information, the transmission bandwidth of Bluetooth is extended to 6Mbps at most and the effective bandwidth is extended to 1~1.2Mbps, thus providing more space for audio source transmission. Thus, it can meet the requirements of LDAC 990kbps high bit rate transmission TrueWireless Mirroring technology, and solve the problem that traditional Bluetooth audio transmission technology needs relay forwarding to occupy twice the Bluetooth bandwidth

FAO FW3 real wireless headset AK4332 DAC chip, with high-performance decoding capability and signal to noise ratio up to 106dB The distortion rate is as low as - 96dB, and the dynamic range can reach 102dB.

The Bluetooth chip of the headset is Qualcomm QCC5141 The dual DSP and dual core CPU architecture is adopted to ensure the dual stability of Bluetooth audio and system operation.
