The state of Bluetooth LE Audio, four years later.

Bluetooth is 24 years old and it's come a long way since the days of me carrying a phone, PDA, and MP3 player, wearing a mono single-unit earpiece with a boom that sat along my cheek. It's a low-power and low-complexity (this means the algorithms used to encode and decode it aren't going to need a lot of processing power) codec that aims to provide high-quality audio even at low data rates. You could listen to that big screen at the airport or take a phone call and still hear the person sitting next to you or a car horn or anything else that's happening without feeling isolated.
