But I guarantee you that, come 2020, you will be hard pushed to find a set of wired headphones that resemble those we wear today.
Yup, commenting just in case I really want to see if this prediction pans out in
only three years: wired earbuds will no longer be sold. Oh! You said, "found". Oh, OK, "found"
I'm biased. When I want to put on earphones, I want to hear, not be heard. That's the primary function. Not to be some bizarre com. THESE Airbuds are totally useless to me, even if I have a device that supports them. Can I take them running, or cycling? That's a good majority of my "not sleeping, not working" time. I don't need another attempt at augmented reality, I need to remember I used to go to places to talk to people, not manipulate a screen, or talk to a computer assistant.
I remember when Bluetooth headsets came out. They were decidedly not cool. Like, "look at the crazy person talking to themself while walking" not cool.
(†Not currently all that much, but hey.)
It's more than me. I'm taking the bet.
