The range of a Bluetooth speaker's Bluetooth connection depends on the specific device, as well as the environment in which it is used. In general, most Bluetooth speakers have a range of about 30 feet (9 meters) when there are no obstacles between the speaker and the device it is connected to. However, the range can be affected by factors such as walls, other electronic devices, and interference from other wireless signals. Some high-end Bluetooth speakers may have a longer range, while others may have a shorter range. It's always a good idea to check the manufacturer's specifications for the specific range of the device you are using.
