Well I got the new fairbuds XL and they are just as good as my Sony's, except completely repairable and the battery can be replaced in minutes.
I think there is obviously a much needed shift towards repairable and sustainable tech. Both the EU and New York State are passing bills and have passed bills for more repairable tech, diagnostics info, spare parts and independent repair facilities.
There are obvious benefits for the consumer in that they can repair or upgrade different parts continually.
Plus with dwindling resources repairing and recycling makes sense for manufacturers as well.
(I've been reading a few Ars Technica articles, but need to find out more).
I think PC builders have been ahead of the curve on this for decades, even some laptops can now be repaired and upgraded internally.
Also with forums like Tom's Hardware, information and advice has never been so accessible. That site is a goldmine of information.
