With completely wireless earbuds, the rule is: when the battery fails, they have to be disposed of. Not so with the Fairbuds, that allow you to replace batteries in just a few seconds. Combined with a repairable design, the earbuds should therefore have an extremely long lifetime.
No, it isn’t. It just has higher bitrates, but still not enough for lossless.
If that’s true it seems like the name is fooling people

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!).
