This is a neat device and it worked great as long as it was not plugged into power, but had horrible background noise if plugged in to either usb or an outlet.

If device is plugged in, the audio has a strong background noise that makes it almost impossible to use while the device is charging.

Still not quite as loud as plugging earphones in directly to the same jack as I used for the TaoTronics, but the TaoTronics will be quite usable for the uses for which I bought it.

No l was not satisfied with this unit that’s why I returned it
