That's kind of OK if you're connecting to a mobile device in your pocket, but there are lots of things I use headphones with. I might be connected to my phone, I might be connected to my laptop, I might be connected to my desktop. Maybe my phone is in my pocket, maybe its on the desk, maybe its on my coffee table across the room.
My wireless headphones work all throughout the house without having to have a device physically on me. I can be listening to a call on my computer, get up and walk to the kitchen, make a snack, and walk back to my office and never miss a beat.
When I am on a videocall with my coworkers and want to fill my glass with water, I like being able to go to the kitchen without having to undock and drag my laptop all over the house.
Same if I need to find something in a shelf.
That is pretty much the only reason I use bt headset.
I'm surprised your bluetooth headphones don't just cut out when you do that. My experience is blutooth has a range of like 30 feet and that quickly diminishes when you introduce walls into the equation.
It really varies based on the equipment in question and the environment they exist in. At home, my headphones paired to my laptop will give me range almost all around the house. Paired to my desktop in the same room, it starts dropping just outside my office. Paired with my phone, I get somewhere in between. With my laptop and phone in an RF-noisy environment, it might only go 20 or 30 feet. With my motorcycle helmet to my phone, it won't even make it if my phone is on a case on the opposite side of the bike, but I think that's mostly because there's almost no chance of direct line of sight without my body and motorcycle in the way and there's no good reflections when out on the open road.
I had to convert that, and I'm shocked. One of your devices is surely faulty. My Airpods Pro with pretty much any device I connect them to, I can easily get 150m (500ft) LoS, and easily 50-100m (150-300ft) with walls in a normal building, with no quality loss at all.
My bluetooth are ok until I reach the kitchen table and fridge because they are close to the door. It starts doing robot voices and cutting out a few step further.
