I generally agree but:

1) Your headphones have good codecs, but they are only used if they match an iPhone supported BT codec. For example AptX will not work with iPhone.

2). Yes double compressing .mp3s is not as bad as it sounds, but double compression can be worse with two different codecs. For example I believe iPhone uses SBC codec for Bluetooth, which is pretty different from .mp3/.aac.

I would be interested in knowing if AirPods solve this by doing .mp3 or .aac pass through.

The headphones do support AAC BT streaming though, which IIRC is Apple's slant on AptX.
