How does one find out what chips are in what USB sticks? Manufacturers don’t make this information available. At best you just find read and write speeds, usually just the max possible read speed and nothing else.

Third party apps: “OK. We’ll show ads. Muted. Behind a black overlay. If we really can’t find a workaround.”

Saying that AptX is lossless since 2016 is blatantly false. And yes, just like with HDMI and USB, AptX standard naming and Qualcomm feature naming schemes are a misleading mess.

There are 4 flavours of AptX (linked article states this as well), and only the latest supports lossless, but is available only on very few chipsets and devices so I even forget that it exists, because for all practical purposes it doesn’t.

Denon Perl Pro, Bose earbuds and Cambridge Audio M100 are the only non-chinese earphones that I know of that support AptX lossless and the latter are not even listed by my local importer. Plus, you need a very specific (expensive) phone to use them because AptX Lossless is not available for all chipsets. Basically, Asus ROG 8 or Xiaomi Redmi K70 Pro for ones available to buy for me, and then it’s not available at every retailer, either, and the b2b wholesalers I have access to through work only list ROG Phone 8 (~1200€ retail).

In conclusion, to make use of lossless AptX you have to jump through many hoops and spend a lot of money—700+€ phone and the 200+€ earphones. The standard is far from being, well, a standard; common and widespread. 99,9% of devices on sale and in use by people only support older AptX standards, mostly AptX HD (which is not lossless!).

No, it isn’t. It just has higher bitrates, but still not enough for lossless.

Counterpoints:

1. Good IEM-s don’t really need ANC. If the silicone tip doesn’t isolate enough you can use foam tips that basically function like hearing protection earplugs.
2. No battery is even better than replaceable battery.
3. Wired IEM-s never get obsolete. At worst you’ll need to replace the silicone tips from time to time, or the cable and today even 20€ Chinese IEM-s have replaceable cables. With good care wired IEM-s can last decades.

Nothing to do with ADA conversions (and digital-to-digital, eg SRC or bitdepth conversion, is completely transparent if done even remotely adequately). Small drivers close to eardrum with good seal just seem to be easier to manage when it comes to frequency response and distortion. Most open circumaural headphones, for example, seem to have deficiencies in lower end no matter the price.

In-ear phones have the potential of having the highest fidelity of all headphone types. So, no, being a “codec snob” is completely justified. Though I personally won’t be using BT phones before we get lossless connection as a standard. Wired are cheaper, last longer and have less environmental impact during production and after EOL.
