When running, climbing or just doing chores around the house, wireless headphones really make it easier to not get them yanked out of your head.
If your use cases don't run into any limitations with a 3.5mm cabled headphone then you certainly shouldn't pay the extra money to be able to freely move your head/body around. For me I am very happy to pay for that as it has improved my experience dramatically.
Spoiler alert: It was not fine.
It's a bit like wheels on luggage... you don't think you need them until you have one, then you never want anything else.
Just to be clear though, I actually use my wired headphones way more... but that's because they're very very good and driven by a good dedicated amp.
Portable is a whole different ballgame.
So, 6 of one, half a dozen of another.
I haven't pulled out my wired headphones in a long time, wireless is just so nice.
Just one example, wireless with noise cancelling means I can listen to a podcast while cooking with the exhaust fan on high, while fiddling with my phone to check up on the recipe, without worrying about the cord.
My AirPods are one of the few things that if I were to lose I'd buy again immediately.
I still love wired headphones too, especially because I never have to think about charging. I run the wire under my hoodie so there’s no issues with it snagging.
In arm's reach I have three different headphones: One is wired XLR, two is dual wireless and 3.5mm wired, three is wireless only. They have all been used in the past 24 hours.
Meet your needs however you see fit, and once you're happy, be happy! Others will choose differently. They shouldn't pressure you about it, and I certainly don't intend to either.
