From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

For context, LDAC is one of the few wireless audio codecs stamped Hi-Res by the Japan Audio Society and its encoder is open source since Android 8, so you can see just how long Windows is sleeping on this. I'm excited about the incoming next gen called LC3plus, my next pair is definitely gonna have that.

I definitely love it for the "it just works" (or rather, you have full control to make it work) factor!

I'm not familiar with the latest in BT audio, but isn't the standard still sub-par in that it has very limited overall frequency bandwidth, resulting in deep sacrifices to fidelity?

I recall a detailed analysis of different BT audio codecs a while back, and the spectrum analysis always showed relatively high noise floor and frequency roll-off (hi-cut/low-cut) within the threshold of human hearing (though admittedly close to the limits). Also, I recall (and this could just be the 2016 tech I am familiar with) that overall bandwidth was limited in that if you played something with low frequency tones, the upper frequencies were dropped, or vice versa. I used to confirm this by using a flat EQ setting, then boosting any range, and you could easily detect the loss of frequency response in the adjacent or distant ranges.

Is this a thing of the past now?

I'd love to say the same but on my Lenovo laptop I get frequent disconnects with bluetooth earphones on Linux alone. Apparently it's a firmware problem with the AX200 board, but even after having updated the firmware and following all the online fixes I still have the problem.

My whole use case for my laptop is getting away from my desk when I want to read something and listen to music at the end of the day, but it's annoying to have to reconnect the earphones every 10 or so minutes. Like everything Linux, it's incredible as long as you have supported hardware and you don't bump into some weird edge case.

I've had BT disconnect issues on a 2015 HP EB 840 G2 paired with my ancient Logitech UE speaker. Not sure if it's the implementation of bluez on mxlinux or my actual bt hardware on the laptop. The result for me is similar to yours: laptop is flaky, so my phone remains my playback source of choice.

Not sure if it's possible on your laptop but I upgraded my Wifi/BT with a AX210NGW on my Thinkpad. Works perfectly now.

I'm pretty sure it is, I'll keep that in mind, thanks!
