I understand that both devices are equipped with Bluetooth modules, but how the sound is able to play instantaneously baffles me.
In: Technology
Fundamentally it is just a radio transmission of data from your phone to the earphones, but there is a reason it took years to go from radio sets to Bluetooth headphones. Those chips are doing a lot and the process is very layered. How do you account for all the other signals bouncing off walls etc? How do you encode the sound as data efficiently? What do you do if you lose a packet of data? How do you minimise the power usage so an earbud works for a whole day? And a bunch of other issues that all got solved and standardised one by one to produce what essentially seems like magic. But yeah, radio waves.
