Wireless earbuds are very small headphones that insert partially into your ear canal and do not need to be physically connected with wires to your smartphone, computer, or stereo system in order to work.
Bluetooth earbuds function by receiving wireless audio signals from the connected device and converting them into sound waves. They incorporate built-in Bluetooth chips and rechargeable batteries, enabling seamless connectivity and extended usage.
Once the DSP process is complete, the earbuds can then send the decoded audio signal to the drivers, which convert the digital signal back into an analog signal that we can hear. In summary, earbuds convert digital signals into sound through the process of analog-to-digital conversion, digital signal processing, and decoding.
