The sound is absolutely for a speaker of this size in order, like a good portable radio of the 60s / 70s. Pairing with trying out various Apple devices always work right away. The built-in battery lasts for hours. The build quality I would let go by. The 'line in' is implemented with the charger cable and proves to be useful when the feeding device is not Bluetooth is possible. The volume control is for both types of coupling with the feeding device. The speaker, in my opinion insufficiently protected with the plastic strap. The diaphragm is open and accessible, and it's just a matter of time before it is damaged. This could have been done better by a diaphragm. Otherwise, I am satisfied with the device.
