This headphone amp is in very good condition with little to no wear. It has been tested and is 100% working properly. These headphone amps seem to have a slight high pitch whine on certain presets, this can be managed with the noise gate in the app and seems to be a know thing with these units. The original packaging and USB charging cable are included.
