During Bluetooth audio transmission, the audio quality is depended on audio format supported by device.
Device such as mobile phones, MP3 and tablet will encode live streaming music in real time and transmit it to Bluetooth headset which subsequently will be decoded into PCM format.
During this process, the audio quality will be affected due to data loss.
Previous Bluetooth version has limited transmission speed and bandwidth.
Due to limiting factors such as power consumption and transmit distance,
a live streaming music can only be achieved by using lossy audio compression. Consequently, audio quality is damaged.
Process by bluetooth 4.2
Bluetooth 4.2 embedded inside our product has higher transmission speed and bigger bandwidth.
The improvements able to reduce damage in audio quality for real time music streaming due to capability to preserve audio quality of the original source.
