Hey Alex, below is a comment on this from the founder, Alexis Corval. He goes into some more details on the audio design in the breakdown he gave us.
"Yes of course Bluetooth is one of the limiting factor and you cannot control the compression it uses. But saying that Bluetooth is THE limiting factor when it comes to audio quality is simply not correct.
I would invite you to compare Astro while it is connected via Bluetooth and also while it is connected via cable, you will be hard pressed to hear any difference even with the limitation of Bluetooth, and that’s because of the hardware on ASTRO.
If you take a bunch of Bluetooth speakers, you can tell that they all have a different audio quality (just like standard speakers), even though they all use the same Bluetooth compression (note: there are some difference between Bluetooth chips, but the best ones are used a lot by different speakers manufacturers), and that is due to their hardware.
Yes Bluetooth has it limitations compression wise, but we are talking about numbers here and what is important is what the listener is experiencing and if you do it right the listener will not be able to tell the difference."
