In fact I'd go as far as say that unlike most mice and in particular all keyboards (which make 0 sense in wireless), wireless headphones are pretty neat. They fix two big issues:

• Getting up in the middle of a call to grab a coffee or so.
• Accidentally yanking wires when swiveling in your chair. You instinctively let go with your hands, so you don't pull the KB or Mouse, but you don't always remember to actively take of the headset before you yanked it again.
