Man I hope they have a good plan for fixing pairing with all the millions of different devices.
Either that or the whole ordeal will be hilarious to watch.

What's with the downvoting? It's astonishing how bicycle riders seem to think everybody except for them is responsible for their safety. Riding on the sidewalk is outright dangerous, I have seen multiple accidents when: * pedestrians got hurt by bicyclists travelling at high speed riding on the sidewalk * bicyclists go around corners and hit pedestrians * bicyclists get hit by cars who couldn't see them at the inters…
It's worse now that Lime and other bicycle rental startups have littered the sidewalks with bicycles. When I'm not running around a bike left on the sidewalk, I'm getting run over by somebody riding one on the sidewalk.
I'm amazed at how often a bicycle rider on the sidewalk will actually warn me to get out of the way. I haven't knocked anybody off of one yet. It's only a matter of time before somebody bumps into me on one and gets hurt.

The killer application for this technology is a bicycle bell you can use to break the trance of phone-staring pedestrians who are randomly staggering down the pavement.
A bicycle is a road vehicle. You shouldn’t be riding on the sidewalk.
There are valid shared bike/pedestrian spaces, like bike trails. Zoned out pedestrians on phones/headphones are extremely common there.

#64Is LC3 superior to existing codecs like Opus?
Opus is not low complexity
Found this:
LC3 at 32 kbps (LC3 32) provides significantly better audio quality than Opus-CELT at 32 kbps and complexity level 0 (OPUS_v114_c0 and COPUS_v114_c0).

Bluetooth LE is a completely different protocol and fixes the pairing issues.

#66Is LC3 superior to existing codecs like Opus?
I don't get it, if I watch an opus music on YouTube, will my headphone transmute opus into LC3? Why this indirection and overcompression? Latency shouldn't exist at all with opus anyway, YouTube just has to send cached audio to the headphone.
Because that requires a Bluetooth processor that can decode Opus. Also, it's a lot less simple than that. You aren't sending the raw audio file to the Bluetooth chip, you're sending an internal audio stream which is already getting converted anyways.
The path is almost always: input audio stream -> decode into raw PCM/PDM/TDM/whatever -> convert to whatever sample rate you're using internally -> move it to your output via some sort of audio bus -> output converts to whatever format IT needs (for bluetooth, this would be into packets to send over bluetooth... for a speaker driver, this would be into signals that drive an actual speaker)
Even if you could send Opus directly, I guarantee there's a reason that they went through the effort of developing an entirely new codec. If Opus met all their needs right off the shelf, then you bet they would spend the effort to use what already exists.
There probably is some sort of latency compensation that you could perform to alleviate this for video content (e.g., most receivers have a delay option to compensate for TV latency), but this falls apart for any instantaneous audio (e.g. button presses, video games, or other dynamic content). You want everything to run as quickly as possible.

Thank you for sharing the customs of your people and/or jurisdiction.

So you go to a bar, don't talk to people, and listen to a specific game solo. Why not just stay at home? The other examples named above make sense, this one seems like a stretch. The whole purpose of going to the bar is to be around other people, the whole point of watching sports at a bar is to enjoy it together.
You could have a speaker on every table without wiring the place all day.
I suppose, but they'd still need electricity so running PoE is no harder and then you aren't worrying about things like interference.

A2DP standard supports both MP3 or AAC.
Optionally.
Right, which pretty much any modern device and host supports. Any Android phone since 8.0 should have LDAC. Pretty much any headphones you would use with this should also have LDAC or AAC (or both).

I imagine the downvoting is due to your erroneous projection of the customs of your locale to the entire larger world. Even narrowly considered, your links don’t really support your point of view (eg there are numerous shared pedestrian/bicycle paths in California, children are allowed to cycle on sidewalks in California, etc).
