MoonDrop Little White Bluetooth 5.2 Neckband Adapter
Bluetooth Neckband with HiFi Performance
The products, by replacing the wireless Bluetooth module (Bluetooth Neckband, TWS ear-hook), have always been shown up in recent years, but it bring the degradation of sound quality, which seems to be a fact.
But, here comes a change.
Bluetooth loss can be reduced by high bit rate transmission protocol, and output performance will be improved by adopting high performance DAC chip, thus the increased power consumption can be solved by larger battery.
Littewhite, a Bluetooth Neckband with HiFi audio output performance.
Adopting Qualcomm flagship Bluetooth master control chip QCC5144, which has a built-in 80MHz CPU core and two 120MHz DSP with ample processing power and is compatible with a variety of Bluetooth audio protocols, providing a hardware platform for DSP sound quality optimization and lossless transmission.
In order to obtain the best possible HiFi sound quality, the QCC5144’s built-in decoder has been by-passed and the digital signal is transmitted through I2S to a high-performance professional audio decoding chip for digital-to-analog conversion and analog signal amplification.
The CS43131 is used as the audio decoding chip, thus bring better performance on portable devices and ensuring that Littlewhite maintains a dynamic range of more than 120dB even under wireless Bluetooth.
