One of the biggest problems with Bluetooth for me is the lack of standardization in codecs. Top of the line using codecs that come from very really generation of Bluetooth audio transmission with horrendous latency. There isn't even a cross operating system compatible basic codec that will guarantee audio and video sync within ~50ms round-trip. There's AAC which is Apple preferred but not every android or Windows 10 support. Fallback to SBC. There's Aptx, Aptx hd, aptx ll, Aptx adaptive which has genuinely come far over iterations but no ios support and windows only supports Aptx. 500$ headphones and the best codec is AAC or SBC shouldn't be acceptable to anyone. It's not about being an audiophile. The nicest DAC in the world can't recover data lost from lossy compression. LDAC is Sony's answer but that's a android supported codec and nothing else and the nicest xm4 don't support Aptx.

The interesting thing is that Chinese companies and fiio are releasing cables and products to turn wired headphones wireless. Kz Az 09 is with looking into. I just ordered a Bluetooth cable that comes with the qcc5141 chip for 40$ and decent iems around 80$ and it will sound better than the best Apple or Sony offerings. Bluetooth 5.2 and newest Aptx adaptive and tws and voice, aac, and ldac just from a cable and can be adapted to whatever iem I want.

Fiio just released the UTWS5 for adapting iems and they have the BTR5 you can plug any headset into and those even support high impedance headphones and can be used as a USB dac.

Bluetooth 5.2 also has a new audio codec LC3. [https://en.m.wikipedia.org/wiki/LC3_(codec)]

All that just to be able to do what regular headphone cables do. There's nothing unexpected about people hanging onto cables. They haven't really been gone, it's weird how a headphone jack is considered a budget feature for phones when cables are the best way to transmit lossless anything.

Cables never left. But the day multiple people can connect to a single Bluetooth source to watch something at the same time, that's when people will care about bluetooth.

In a different world, where hd audio wasn't stuck behind a proprietary codec in the US. There was room fm radio to take the place bluetooth audio has been forced to take.

I personally use an an app to make my headphones wifi capable. Soundwire server listens transmits audio to my android phone 40-50ms latency. I keep wired headphones plugged in at all times. I get the range of wifi. Lossless audio transmission bandwidth is so tiny in the world of wifi, it's a rock solid connection 5 to 6 times further than Bluetooth in residential locations. I once tried it at my university and could leave my laptop at one end of the building and heard it playing in the connected building due to how they set up the network. 802.1x authentication. 400ft away minimum.

I also use viper4android for on device audio equalization on android. PeaceAPO for windows 10.
