The clips that let you fasten it to the collar of your shirt are life changing. Completely elimates the weight of the rest of the cord from your ears and any weirdness when you move your head. I wish more headphones and IEMs came with one in the box.
That's debatable. As far as I'm concerned I prefer being annoyed by my occasional lack of care rather than wondering what software quirk makes my phone call come out of the wrong device.
At least I can identify the cause quickly and make my best to avoid the issue.
I carry my backpack or have a jacket on me at almost all times, and having the headphone cable holes in each has prevented this from happening anywhere as often as it used to. Plus the reliability of wired headphones has reigned supreme that I sold my AirPod Pros a few weeks ago after they sat for about a month or two between use, while my corded headsets are used almost daily.
Even for desk use, wired headphones feel like being leashed to the desk. It's amazing to be in a meeting and then be able to just mute yourself and walk off to have a drink while still listening in.
Somewhere in my audio setup there is a ground loop. I don't know where, and I'm yet to be able to work out what is causing it. But that alone makes wireless appeal at my desk very much.
If you have an IEM with a sturdy cable wrapped around your ear, snagging it on a door handle yanks the connector out of the Lightning to 3.5mm adapter instead.
