Does this finally fix the shitty audio quality when using a wireless headset's microphone?

I believe this has already been fixed by LE audio.

But support (on both ends) is quite rare, experimental, and needs to be explicitly enabled.

It's been difficult for me to find headphones with LE support. And also I've seen some of them announced support, just to remove it later because the firmware was behaving so bad.

Haven't checked in a while, so I don't know if is there something reasonable now that doesn't cost like $500 or so.

Yeah, my experience has been that bunch of features just don't work when LE is used.

E.g. on my WF-1000XM5, I can't use multipoint connection, lose per-headphone/case battery status, Voice Assistant support and some other details.

The WF-1000XM5 beta Bluetooth is pretty good in the latest firmware update. Even though it is listed as beta I use it all the time. And they are pretty decently priced at the moment

Yes, very frustrating... I was on the lookout for new headphones that "just work" and LE Audio / LC3 support was a must for me. One of the more frustrating tech shopping experiences I've had so far.

Landed on the JBL Tour One M3, they sound okay and support LE Audio. They have some interface problems (Auto-Pause and automatic speech detection is way to sensitive for me) but you can tweak it so it does "just work" (mostly).

Classic and LE are completely different protocols, from physical layer and up. It must be that it doesn't make a lot of sense for manufacturers to invest substantial effort in it.

Which makes sense when you know it started life[1] as a separate protocol called Wibree by Nokia, which was specifically designed[2] to be usable by Bluetooth RF gear:

A major tenet of their design was that “it can be deployed with minor effort into devices already having Bluetooth, e.g. cellphones” with the added requirement that a “common RF section with Bluetooth must be possible”.

I recently got the Tour One M2 and was pretty disappointed with the audio quality (both normal bluetooth and LE audio). Noticeably worse than my previous wired headphones, which were also cheaper. The touch controls are also terrible, and I dont like that noise cancelling is on by default with seemingly no way to change the default setting.
