OK

pu2. It's about 5 to 10 meters, but it's different depending on the device

OK

pu3. Since it is connected through Bluetooth, it matches the Bluetooth connection distance and the Bluetooth connection distance varies a lot from product to product, so it is difficult to say exactly how much it is. The good thing is that it connects a few tens of meters. But the farther you get, the less transmission you get
