The FiiO BTR7 offers a fully balanced audio architecture, which means that each channel is driven separately.

To ensure that no detail is lost with such Hi-Res formats, you can also connect your smartphone, laptop or any other compatible device to the amplifier via a USB-C or Lightning cable (the FiiO BTR7 is available in two versions) and enjoy music in the highest quality. Sometimes a cable just might be nice after all. One-Click Dongle Mode BTR7 can also be used as a Portable USB DAC/AMP. Users will be able to use it as a USB DAC with a simple one-click dongle mode. The switch is available on the side of the device, Simply press the “CHARGE” button with one click to switch into and out of “dongle” mode.
