A2DP is a system that specifies how to transfer stereo quality sound from one media source to another device. It is among the Bluetooth standards that different technology companies are under a joint venture. It is often found in mobile devices such as cell phones.
Bluetooth connectivity is one of the rare technological wonders that has survived from the past. Bluetooth headphones, on the other hand, have spent almost a decade as a limited niche with tech geeks. Bluetooth headphones, which have incredible varieties on the shelves of electronic stores, continue to be on the agenda with their different features. You can also purchase Bluetooth headphones from many online retailers. But it should not be forgotten that these headphones, like every electronic device, have a certain lifespan.

In this article, we will examine the title of A2DP (Advanced Audio Distribution Profile) and how it works. We'll also talk about the three Bluetooth technologies and alternative features regarding exactly what the volume level of your Bluetooth headset is and what you're looking for in a new headset.
A2DP is known as the basic Bluetooth stereo streaming protocol. AptX is known as an advanced codec specially designed for Bluetooth. Finally, Apple's W1 chip system, like any Apple electronic device, is unique and only works with Apple hardware.
What is A2DP (Advanced Audio Distribution Profile)?
A2DP is known by its English acronym Advanced Audio Distribution Profile. In Turkish, it means Advanced Audio Distribution Profile. It doesn't mean much in the context of a system with audio streaming, but as one of the earliest parts of the unified Bluetooth specification, A2DP is a profile more or less considered for streaming audio over Bluetooth. It doesn't matter if it will work with aptX, as all Bluetooth-based audio products (headphones, speakers, mobile phones, laptops) you buy will support A2DP.
How A2DP (Advanced Audio Distribution Profile) Works
This advanced audio distribution profile works in stereo and supports most standard audio compression codecs. The recommended subband encoding (SBC) codec supports up to 345 kilobits per second at 48 kilohertz. This corresponds to about one-third of standard CD sound quality. In short, it is equivalent to a high-quality MP3 recording. Due to the high "lossy" compression in the SBC codec, the authenticity of the audio quality lies somewhere in the 256kbit/s range, which is quite low rate.
A2DP also supports methods such as audio encoding and compression, such as MP3, which is one of the popular applications today. If the audio source is already compressed with a format such as MP3, AAC or ATRAC, it does not need re-encoding in SBC to stream from the source device. Thanks to A2DP's maximum audio bandwidth of 728kbit/s, it's possible to at least begin to approach the audio limit of so-called "high quality audio" with only the basic standard.
Unfortunately, very few hardware crafters seem to use this feature. Most A2DP-only devices re-encode audio to SBC and decode with the receiver end. As a result, this situation complicates the whole process and causes a further deterioration in sound quality.
