Well it's always nice to have options. But most likely will never happen because I think Sony asks for a licencing and companies to pay to use it.
Aptx-HD would make more sense actually.
Also, most LDAC compatible devices cast their LDAC in 330kbps which actually gives a worse sound than SBC and...
I asked chat gpt for a codecs summary:
Bluetooth audio codecs play a critical role in determining the quality of wireless audio transmission. Several Bluetooth codecs are available, each with its own strengths and weaknesses. Below is an in-depth comparison of the most common Bluetooth codecs...

That's unfortunate, especially considering it's supposed to have ESD and DC protection as stated here:

I hope your headphones aren't damaged.
For information the SMSL SU9-Pro output impedance is 100Ω (100 ohms) for Single Ended.
SMSL just sent me the information. Trying to get the info for balanced output.
AAC vs LDAC it's totally normal since AAC compression gives you more or les a crappy mp3.
Sony ANC doesn't give me the underwater effect. Bose does.
And regarding the Bathys, are you in 1.54? What settings do you use in the focal app? What is your bluetooth phone?
I don't really agree. First I'm not sure you'd be able to hear any difference between LDAC and Aptx.
I personaly don't hear a difference between DAC usb lossless mode and aptx. So I don't think it would make that much of a difference. Even with the Stealth and my SOTA stack the sound is super...
