I failed to notice it 😂
I was in the gym, struggling as always with my ear buds (tiny ears, need really loud music too) when I noticed the girl next to me had traditional style headphones on.
Looking round the gym, headphones outnumbered earbuds by two to one, and it's the same in the street, on the bus etc.
I bought some headphones and they are HEAVENLY. In fact my workout was twenty minutes longer because the tunes kept me going.
I'm behind the curve obviously - when did headphones take over?
