What is A2DP Bluetooth technology?

Bluetooth A2DP (Advanced Audio Distribution) technology is one of the Bluetooth modes that helps the phone to output stereo sound with the same quality as when listening to music on conventional wired headphones. Users simply turn on the Bluetooth mode on their A2DP-enabled phone and connect to a wireless headset (which also supports A2DP technology), then choose a favorite song and enjoy them.

What is stereo sound?

Stereo sound is the type of sound that comes from many channels, many sources from the left earphone to the right. That is, there will be audio parts played on the left earphone, there will be audio parts played on the right earphone. And this sound synthesis, will give you a more real feeling, “better”. Stereo is different from Mono sound, which is a type of sound that has only one direction, a single source, and it sounds the same no matter what.

Previously, Bluetooth headsets only had the function of listening and receiving calls from the phone. The birth of Bluetooth A2DP technology is considered a commendable improvement in supporting users to experience listening to music on their phones without cumbersome wiring.

However, the sound quality when listening to music with wireless headphones is often not as good as wired headphones when they are too far away from the phone or when encountering obstacles. But if at a close distance and without obstructions, the sound output will be very good.

However, to make sure that both devices can be compatible with each other, try connecting the headset to the phone first before deciding to buy.
