Optimistic outlook without reasonable skepticism is probably at least something you should not strive to achieve.

HN discussion did not particlarly have "reasonable skepticism".

This is probably because people (i) were not aware that there had been many other hypes about RTSC before but less publicly visible all proved to be false, (ii) not being able to accurately judge the technical quality of the initial evidence, (iii) uncritically believing that the data in the initial preprints was proof for superconductivity because their authors said so.

Wikipedia seems to be a good first stop here, https://en.wikipedia.org/wiki/Cargo_cult and contains several other useful references for entering the rabbit hole of what these cults are and why they appeared.

The wag who dubbed various false alarms of room temperature superconductivity in the 1990s as USOs (Unidentified Superconducting Objects) got it quite right.

First there is the condensed-matter equivalent of blurry photos of floating saucers (or small disks like here) and lots of excitement, followed by investigations either not seeing anything or identifying the objects as weather ballons. The social media reaction is also similar.

This preprint identifies a weather balloon that was conspicuously close the site of the original photographs.

Also, on the sentences in the manuscripts trying to explain the effect: I think that is wild guess at best. The measurement results done in the manuscripts probably can be taken at at face value (at least until there is a reproduction). Whether they really indicate superconductivity or something else that looks like it in some of the aspects is then a different question.

Get a headset that has Faststream or bidirectional APTX-LL A2DP vendor codec, and use it with BT stack that implements these codecs (e.g. Linux/Pipewire). Such devices are very hard to find, and aptx-ll in most devices is not bidirectional. I know only some headsets by Avantree that have it.

Or, wait for a few years for Bluetooth 5.2 LE Audio be available in consumer devices.

There are vendor A2DP codecs that support duplex audio (faststream; aptx-ll optionally) but very few devices implement them. Software support is also fairly bad, although on Linux Pipewire does support them.

Also iirc CSR has a vendor codec (Auristream) in SCO transport that supposedly provides higher quality. Not sure how much better it is, or what software supports it.

So certainly better duplex quality is achievable. But there may be some licensing, hardware, or software support constraints that have prevented them from becoming more common.
