You are so right! Why are all the audio manufacturers making wireless headphones and earphones, because we are a dying breed. Most of what we buy will be vintage in no time.
From the other end, wireless tech is improving fast. Music streaming is mainstream and gaining in popularity. A bit more improvement in LDAC, AptX and we (audio enthusiasts) are relics of the past.
Tell a "layman" you are an audio enthusiast and the first thing they ask is a recommendation for a good set of headphones or earphones with ANC! You say, you are into wired sets and you get a weird look.
The huge companies are moving fast, with huge budgets churning out good imitations of audiophile gear. Above all it does not make financial sense to focus on audio enthusiasts, when there is a huge "lay" consumer market waiting for good quality sound.....why would Apple, Sony, Samsung bother to invest so much money in audio otherwise? They, ("lay" consumers) enjoy music just as much as we do, they can tell good sound......sorry, but not long to go before we become dinosaurs.
