I say this as someone who just bought 4 pairs of headphones today.
I think the main benefit of going wireless in the first place is so that the cord can't break. I've lost several electronics to broken cords that short over the years, including headphones. A strap is functionally different than a cord with a wire carrying current through it for the purpose of audio or power transmission, and will not break nearly as easily. Another obvious benefit is that wired headphone cords get tangled on things. I think a small strap is not going to get tangled nearly as easily as a 5-10ft cord going to another device.
I suppose that some people prefer the style of not having a cord. But then that just means that the strap is not for you.
For what it's worth, I can certainly appreciate the sentiment of channeling Filthy Frank to roast anything AirPods related. I feel like 2/3rds of the people who wear Airpods are doing it for the Apple brand name, especially the ones who go out of their way to insist they're not, and then spit off a whole bunch of great things about them that can be easily said about many of their competitors for half the price.
Unless something has changed in the last few years, earbuds always have lower sound quality when you pay the same amount of money as a comparable brand's headphones. Take everything I'm about to say with a grain of salt, but I think the only good reasons to wear in-ear earbuds anyway is if you need the comfort of being able to lie on your side with them, need something ultra-light and ultra-portable, or you're athletic and want something that doesn't bounce around on your head while running etc. To me, earbuds, unless used for the purposes above, represent vanity, trendiness, and servitude to the cold roboticism of the social hierarchy. Headphones represent love for the music, respect for the individual, and a message: people that don't respect that can go fuck themselves.
I'm speaking in broad generalities about my interpretations here. Not everyone who wears earbuds is a tool of the societal ladder, and not everyone who wears headphones is a music-loving DJ, a working-class hero, or a proletariat punk.
