It's very dependent on the devices, ear buds given their size will be
particularly low power. Larger devices such as keyboards can exceed
Bluetooth's stated 10m range by a considerable margin.

That would be massive overkill for most of the things Bluetooth is used
for, and lead to reception problems as far more devices would interfere
with each other. Plus your ear buds would look more like a set of over
ear cans.
