Bluetooth headphones have become extremely popular due to their convenience and wireless capability. However, many users often experience distorted sound that resembles the audio being underwater. To understand this problem better, it is essential to comprehend the underlying technology of Bluetooth headphones.

Bluetooth headphones rely on radio waves to transmit audio signals wirelessly from the source device to the headphones. They use a short-range wireless communication protocol known as Bluetooth, which operates on the 2.4 GHz frequency band. This communication involves two main components: a transmitter (such as a smartphone) and a receiver (the headphones).

When you play audio on your device, it is converted into a digital signal, which is then sent to the Bluetooth transmitter. The transmitter encodes this digital signal and transmits it to the receiver in the headphones, which decodes the signal back into audio that you can hear.

Understanding this process helps us identify potential issues that can cause distorted sound. By examining the various factors that can affect Bluetooth audio quality, such as interference, audio codec compatibility, and connectivity problems, we can troubleshoot and fix the underwater sounding audio problem.
