What you said is super misleading. No, it's not the same as a STANDARD 2.4GHz radio signal. By standard I meant in the sense of wireless microphones. But I can understand the confusion.
Yes, Bluetooth uses the same ISM radio band of 2.4GHz. But so do microwave ovens, garagedoor openers, RC planes, WiFi routers, car alarms, some radar, and any number of different devices and technologies.
Bluetooth doesn't use the 2.4GHz band the same way that wireless microphones do. They are completely different technologies built upon the same basic technology. Bluetooth does not directly encode a 'raw' audio electric signal. There isn't a designated transmitter and a designated reciever. Bluetooth sends encoded digital data packets back and forth, in two directions. There's constant communicaiton between the two, and there's a lot of little bits of system data going back and forth. There simply isn't enough bandwidth left over to deliver even close to the same level of audio quality without first compressing the signal. Which is exactly what most Bluetooth audio implementions do. Until recently, with the sparsely-supported aptX codec, the idea of lossless audio over Bluetooth was laughable. And despite how well that niche aptX codec that requires specific hardware works, it's only giving you a close aproximation of 16bits at 44.1kHz. Why settle for just that?
Trust me: Never use any kind of Airpod as your primary microphone. You're recording heavily compressed audio that isn't suitable for post production. If the audio clips, you won't be able to recover any of the lost signal information. But if you don't trust me, trust the manufacturer.
From Apple's own website:
"AirPods, AirPods Pro, AirPods Max, AirPods (3rd generation), and Beats wireless headphones use Apple’s AAC Bluetooth Codec to ensure excellent audio quality. Bluetooth connections don’t support lossless audio."
