The version numbers of the standards updated by Bluetooth, Wi-Fi, HDMI and other leading industry groups are basically the latest and most advanced. [image] Bluetooth logo, but "Bluetooth audio" is its special existence. It complies with the Bluetooth 3.x standard (Classic Bluetooth), and both Bluetooth 4 and 5 will continue to use the same "A2DP" as 3.x (one of the configuration files for Hi-fi audio that shows the communication method and connection process). LE Audio is the Hi-fi audio standard that uses the Bluetoot LE connection path in Bluetooth version 5.2 or later. Is not compatible with Bluetooth 3.x Bluetooth Audio (hereinafter referred to as Classic Audio) and is not committed to supporting Classic Audio because it supports LE Audio Depending on the manufacturer's design, you can make playback devices (such as smartphones or other transmission devices), such as headphones, that can use both LE audio and Classic audio. At present, there is almost no circulation of the corresponding products of LE Audio, but the environment is improving. First, the existence of the corresponding chip (SoC). For example, Qualcomm has released QCC305x as a Bluetooth SoC that supports LE Audio, and Bluetooth headsets equipped with this chip may support LE Audio. SoC "Snapdragon8Gen1" for smartphones can also support LE Audio, so if it is a smartphone equipped with this kind of SoC, it may be able to play in LE Audio. In addition to Qualcomm, chip suppliers have also released LE Audio-compatible SoC. What is inarticulate about "maybe" or "maybe" is that it is actually headphone makers and smartphone makers that determine the support of LE Audio. Even if SoC itself has the potential to support, it is not necessary to install a chip that enables LE audio in the product. In addition, you need support for smartphone operating systems (Android operating system and iOS). In other words, in order for end users to enjoy audio playback in LE Audio, "headphones, smartphones, smartphone operating systems and other system software" must be complete. LE Audio-compatible SoC will be released by 2021, so it is expected to launch products with LE Audio this year.

Tolerance at sea; tolerance at sea.
